Carnatic Music - Audio Engineering Basics

NOTE:  The goal of this post is to give some general pointers to those managing audio in Carnatic music or Bharatanatyam programs and written for a non-mathematical, non-technical person.  All too often, the enjoyment of a program is really affected by audio problems. Hopefully, these comments will be helpful to some.  I have kept things at an elementary level and avoided jargon as much as one can.  I have to be cryptic to save on space.

1. Frequencies are measured in Hertz.  Also kH stands for kilo Hertz or 1000 Hertz, ie one thousand cycles of the signal wave per second.  Sharper, squeaky sounds are in the higher frequency range. Thus, for example, Balamularali Krishna's voice may traverse a frequency range that is lower than the one traversed by Musiri Subramanya Iyer (or a female vocalist like MS).  The Hz level changes continuously as the singer "goes up or down."    Understand the frequency ranges of voice and various Carnatic instruments.  This is important in setting the equalizer. [Male voice: 100Hz - 1800 Hz; Female voice: 150Hz-2500Hz; Violin: 350Hz - 4000 Hz; mrdangam: 100Hz-2000Hz; these are approximate].  Just to understand how these numbers relate to what you hear consider these: if you push up the higher frequencies, a male voice will start sounding like that of a female and a female voice will become very squeaky,  violin will become unbearably high pitched and squeaky, mrdangam right will start sounding metallic.  Push up the lower frequencies and you distort sound again - some examples: voice and mrdangam right (sollu) will become less clear; violin will boom in lower octaves; left side mrdangam will boom drowning most others.  Got it?  This also gives you a hint on what to change if you see these types of problems.  Play around with your home equalizer if you have one and if not with the treble (high frequency) and bass (low frequency) knobs.  Best is to try doing the experiment with only audio portions where only one musician is performing.   [Unfortunately, many systems today like Bose don't let you do anything; trust me, they provide less optimal sound than what someone who knows, even moderately, what to do with manual controls.  It is just like using your camera in Auto versus Manual. Rarely will a professional put the camera in the auto mode unless they know they won't have the time to compose their pictures!].

2. In terms of equalization thus for a male vocalist, I may set the equalizer with the frequency  around 1200 or so high and tapering down to the sides; for a violin may be centered around 2000 Hz; etc.
Make sure successive frequency knobs form a reasonably continuous curve.
Since you are not doing some fancy stuff with a separate equalizer for each instrument or musician, use the main person as your guide for this.  Things may have to be changed later depending on the auditorium, the size of the crowd (that alters sound characteristics ), etc. for which your ears are your best guide.  There is no one single set of numbers that work always.  So, treat these as starting points.
After setting the equalizer thus, adjust individual instruments or channels with the frequency knobs low, mid, high on your console which cover different frequency ranges.

3. Volume and Gain: One big cause of problems is setting the gain high.  Without getting technical, think of gain as the input volume level.  If gain is set high, a small movement towards the mic by the musician can amplify things very much.  Such abrupt moves will make them sound like they are shouting or screaming.  (Hear those awful squeaks in the auditorium? Most of these are due to high gain settings.)  A common mistake I see with most audio people in Indian programs, including so-called professionals, is that they treat the gain control as the main tool for increasing or lowering volume.  That is really asking for trouble.  Golden Rule 1: Try to make do with the minimum possible level of gain to avoid squeaks and overloads of your system.  How do you find it?  Here is a simple trick.  Set the volume control at 0 (i.e., at center), let the person play or sing and increase gain just to the level that is comfortable.  From then on change using only the volume knob!  Volume knob is what controls the output level.  Golden Rule 2: Move the knobs gently and in a continuous motion at a very slow rate; especially so with gain.

4.  If you hear the violin or the left side of the mrdangam booming, reduce the lower frequencies.  Some violinists and vocalists will ask for more "base" without realizing a little bit what it can do to how they sound.  Make them play the lower octaves and use that as a guide.   Pay attention to the right side of the mrdangam; is the sollu clear?  if not ,you don't have enough treble (higher frequencies) for that; does it sound too metallic (then you have too much treble or are using high frequency ranges too much).

5. Never work without a stage monitor.  Make sure you can increase or decrease the volume on the stage monitor without affecting the way things sound in the hall.  Don't run the stage monitor too high.  Then amplified sound enters the mic, gets amplified again, and this process repeats God knows how many times since things travel at speed of light, overloads your channel, and you get a terrible squeak; in the worst case, it blows your equipment (yes, I have seen that happen too!)

6. Unless you have undergone some serious professional training, stay away from things (especially done manually) like Effects (Reverb) which some musicians will ask for although they have no clue whatsoever what it means or how it affects sound.  [You may be able to get away with the automatic setting of Vocal-SmallHall or Vocal-LargeHall for most Carnatic programs giving good reverb but beware of hall reflection properties of sound.  If it feels like you are hearing multiple versions of the same sound, don't use it!]  Smile, nod your head, do what you have to do.  In my long years, the only musician I consider as knowing anything about sound engineering is Sangeethasagara Balamuralikrishna.  How I wish a day comes when no one is allowed to ascend the stage without some minimum training on using the mic and the essentials of audio!

Also, when it comes to recording, please set the peak level at about -6dB.  One common error I see especially from India is to set it at 0dB resulting in frequency clipping.

Some other golden rules: #3 Go  and listen from various places in the auditorium and readjust. #4 Dont respond to each and everyone who comes to you and asks you to change this or that.  #5 Have some trusted people (like those who you know can make a good judgment about sound quality) who can tell you. #6 Don't set up and walk away for good.  Unexpected exigencies do occur.  #7 Don't get too cocky; there is a heck of a lot to learn, and at any stage, what we know is a very small part of what is out there to learn.

INDIAN HEALTH - PART 3 - DIET


This is a summary of a great book and provided as community service to you. Your feedback is appreciated.  My advice: Buy the book and use it as a constant reference.

Book: The South Asian Health Solution
Author: Ronesh Sinha, MD
ISBN: 978-1-939563-05-7

Note: This summary is to quickly get us moving in the right direction and is not a substitute for reading the book which abounds in case studies and much greater detail than what is presented here.

PROBLEMS OF TYPICAL INDIAN DIET

Excess Carb: The key number is Net Carb defined by
NC = Total Grams of Carb – Total Grams of Fiber
(MyFitnessPal.com provides NC values for most Indian food for free.  Surprise or shock yourself as the case may be by playing around. 1 home made dosa=34g !)

If you meet the metabolic six-pack, limit carbs to 150g/day.  May need to move to 80-100g to burn fat depending on how far you are from the norm.

    For someone meeting the criteria given in Part 2, the recommended NC per day is in the range of 100-150 grams, although the very physically active may tolerate more.  Those who are challenged with respect to obesity measures will have to drop down to 80-100 grams of carb per day to achieve fat burning.  But most Indians routinely consume 300+ grams per day; most don’t even know that.  They chase some other numbers like total calories or total fat etc. incorrectly.  They also harbor many myths and do not understand that certain fats (like coconut oil and ghee), in the absence of excess carb, are not harmful but become fattening with excess carb. Excess carb leads to insulin resistance and unhealthy visceral fat lining internal organs (abdominal fat is a sign of that) that generates inflammatory agents.  The book recommends carb control as the most important step in controlling many of the metrics associated with the metabolic six-pack.  Patients are seen to show significant progress even in 3 months with proper carb control and exercise.

Warnings: (i) You must avoid too much loss of fluids and sodium if you are moving from a high carb to a low carb diet.  Typically, people may need only a cup of broth.  (ii) If you have a health condition like high BP, diabetes, or a heart problem, you must consult your doctor or a trained nutritionist before you make drastic reductions of carb. (iii) Those engaging in over 1 hour of intense exercise or games (not casual strolls) can take an extra dose of carb in the form of a sweet potato or a serving of rice 30 to 60 minutes later to replenish the glucose store in the muscles.      

RECOMMENDATIONS

1.    Flat Breads: Avoid or severely limit high carb foods (Paratha=47g; Naan=35g, chapatti=24g, masala-dosa=30g, 1 bread slice=15g; all numbers approximate and can vary with brand etc.)  Replace with low carb food (Coconut Flour chapatti=3g; almond toast =1 g; almond flour pancake =2g; romaine lettuce=0g).  Try chopped cauliflower for masala in place of potato.  Try adai or pesarettu instead of dosa high in rice content with more lentils.

2.    Starchy Vegetables:  Substitute starchy vegetables (aloo sabji=40g/cup; aloo paratha=40g; corn 1 cup=30g; peas 1 cup=20g; pumpkin and squash = 20g/cup) with (cauliflower=2g/cup; crunchy leafy vegetables; sweet potato; finally, spaghetti, zucchini, summer squash=5g/cup)

3.    Rice etc.: Intake in the Chinese population of rice is apparently 600g/day of carb (won’t be surprised if it is so for many in South India).  Substitute high carb items (1 cup white rice=40g; 1 cup basmati=76g; 1 cup spaghetti=40g; 1 cup brown basmati=68g) with  alternatives (cauliflower rice =4g; shredded cabbage=4g; Shirataki rice and noodles = 1g.  Other alternatives are chopped broccoli, carrots).

4.    Lentils etc.: Substitute high carb items (cooked dal=30g/cup; kidney beans=30g; chickpeas=30g) with (rasam 5g+vegetables; add volume with protein foods like paneer and nuts; add richness with toasted almonds topped with extra virgin olive oil, ghee, or coconut oil.)

5.    Sweets: Avoid high fructose corn syrup, liquid sugar like juices and sodas, designer coffee drinks, mango lassi, fruit smoothies.  (1 raw mango=30g; 1 cup pineapple=20g; 1 banana=24g; 1 cup prunes=60g; 3 dates=50g) .  Instead, use berries (1 cup blue berries=15g; raspberries=7g; strawberries=10g).  (There is not even a need to mention Indian sweets which are sugar high.  A strategy adopted in parties successfully by someone I know is to either take the desserts first so as not to overload oneself after the meal, or to consciously make room for some and go easy on the main courses.)

Breakfast: The author recommends having breakfast after an exercise, so that the muscles draw their glucose from the accumulated belly fat.  Those, who can, should consider an omelette, soft-boiled eggs or scrambled eggs for protein.  Avoid cereal from boxes laden with carbs as well as oatmeal-banana.  Instead, he suggests almond meal, almond flour, or coconut flour pancakes, low carb Greek yogurt, berries and nuts.  For him, skipping breakfast altogether is not as sinful as some make it out to be either, and many may find themselves feeling less hungry as they do around ten or eleven after a glucose heavy breakfast.  He also recommends intermittent fasting by those who can do that.

Protein: Lentils are the main source of protein for vegetarians, but unfortunately they come laden with carbs.  A couple of eggs is highly recommended by the author who asserts that will increase your cholesterol less than a bagel or high fiber cereal we normally eat.  Nuts and seeds (almond, macademia, sun flower seed) are good sources of protein, minerals, fiber and healthy fats as are butters made from them.  Quinoa is high in protein, calcium, phosphorous and magnesium but be aware of its NC.  Almond flour or coconut flour breads,  a bowl of lentils with ¾ vegetable content (don’t overcook vegetables) is a good choice.  Protein shakes with regular or coconut milk as base with some added nut butter is a good choice.  Avoid fruits and prefer vegetables for shakes.  Vegetables with high protein content are: asparagus, broccoli, Brussel sprouts, cauliflower (do not overcook!).

Fat: Saturated fats found in dairy (milk, butter) and in coconut (oil, butter, flakes, milk) are good when not consumed with excess carbs. Monounsaturated fats (olive, extra virgn olive oil, avocados, macadamia, almonds) are heathy; don’t heat the oils in this class to high heat.  In the case of Polyunsaturated fats, Omega-3 is good, but avoid Omega-6 (vegetable oils are big offenders) which creates inflammatory effects.  Transfats and partially hydrogenated fats are unsuitable for human consumption.

Additional Remarks: Indians tend to exhibit Vitamin D deficiency.  A daily vitamin supplement is worth considering if the daily diet is not providing enough vitamins and minerals.  Indians according to the author lead a highly oxidized lifestyle, which accounts for high rates of inflammation. (We take early AM, as first thing in the morning 15 minutes before anything else, the anti-oxidant 'nutraMetrix Isotonic OPC-3' on the advice of our own doctor and have found it to be very helpful. A capful is supposed to have anti-oxidants equal to several glasses of red wine.)
Please read the book for more information on food for children, pregnant women, etc. as also for understanding better the rationale.  At its price, the book is a great investment.  Treat this set of blogs only as a quick refresher or summary of the bare minimum facts.

INDIAN HEALTH- PART 2 - METRICS & THRESHOLDS

This is a summary of a great book and provided as community service to you. Your feedback is appreciated.  My advice: Buy the book and use it as a constant reference.

Book: The South Asian Health Solution
Author: Ronesh Sinha, MD
ISBN: 978-1-939563-05-7

Note: This summary is to quickly get us moving in the right direction and is not a substitute for reading the book which abounds in case studies and much greater detail than what is presented here.

THE IDEAL NUMBERS FOR ASIAN INDIANS

      We will first recall the target metrics to watch and the thresholds.  Explanations on the significance of these metrics etc. are to be given in a later post with our focus on getting to actionable items first. [These summaries are also for myself so that I don’t have to keep searching through the book repeatedly.]
     The book recommends a set of six goals, which the author calls “metabolic six pack.”   They are both goals to aspire for as well as a check with regard to how healthy one really is.   Abnormalities in them are often indicators of ongoing or soon-to-occur problems.  It is, however, counterproductive to get hung up on the last inch, or the last pound, or whatever measure and stressing out.  However, the closer you move to the ideal, the better off you are.  The key is to start making a constant movement in that direction and maintaining once good levels are reached.

METABOLIC SIX-PACK: (1) If you are a male, bring your waist circumference to 35 inches, and if you are a female to 31 inches; (2) Get to a triglyceride level below 100 mg/dL (1.13 mmol/L);  (3) Get to HDL cholesterol to a level greater than 40 mg/dL (1.03 mmol/L) if you are a male, and above 50 mg/dL (1.29 mmol/L) if you are a female; (4) Reduce your systolic BP to 120 or under and diastolic BP to 80 or under; (5) Bring fasting glucose level to below 100 mg/dL (5.6 mmol/L) and A1C to below 5.7; (6) Get hs-CRP level (inflammation marker) below 1.0mg/dL.

Two ratios:  Two ratios strongly recommended for South Asians and associated targets are: (i) Triglycerides/HDL < 3.0; (ii) Waist/Hip < 0.9 for males, and < 0.85 for females.  [Measure waist (tummy) at the level of the navel without tucking in, and hip at the widest point keeping a tape measure as parallel to the ground as possible.]





A crude measure of fitness is BMI (the Body Mass Index).  It is defined as:
           BMI = (703 x Weight in Pounds) / (height in inches x height in inches)
                    = (Weight in kg)/(height in meters x height in meters)
Note: 100 centimeters make a meter.
Some rules of thumb accompanying this measure for South Asians are:
        Underweight if BMI < 18.5; Healthy if BMI is between 18.5 and 23;
  Overweight if BMI is between 23 .1 and 25; Obese if BMI is greater than 25

WARNING: Though easy to measure, the BMI is not adequate as a measure because, among other things, it does not differentiate fat and muscle.  Abdominal obesity is a better indicator.  Stay with the metabolic six-pack measurements.

    The book  (Appendix B, pages 358-360) provides a detailed set of WHO recommended parameters for an even larger variety of metrics.  The typical health challenged Asian Indian, however, will do well to concentrate on the above and to work on improving them unless there are specific reasons identified by a physician.

ADDITIONAL COMMENTS
1.     There are many other metrics and associated thresholds given by WHO.  One of these is Total Cholesterol/HDL < 3.5.   An advanced lipid profile may be needed if you are violating this or other cholesterol based requirements in the metabloc six-pack.

2.     Blood pressure: You are pre-hypertensive if your systolic is between 120 and 139 or diastolic between 80 & 89; Stage 1 High if systolic is between 140 & 159 or diastolic is between 90 and 99; Stage 2 High if systolic is > 160 or diastolic >99.  If not normal, it is recommended that you monitor your pressure at different times of the day daily at least for two weeks, make a chart, and share it with your physician.

3.     Blood Glucose: Normal if fasting glucose < 100 mg/dL, A1C< 5.7, and OGTT  < 140.  OGTT refers to Oral Glucose Tolerance Test, which is not administered unless there is a need.  Pre-diabetic if fasting glucose is in the range 100 to 125, or if A1C in range 5.7 to 6.4, or if OGTT between 140 and 199; Diabetic if fasting glucose > 126 or A1C > 6.4 or OGTT > 200.

4.     Specific requirements on LDL cholesterol is not specified by the book due to the reason that LDL itself decomposes into smaller and larger particles, and smaller ones cause problems.  Thus one can have a “normal” LDL level although could be quite unhealthy since a large portion of the LDL is made up of smaller particles.  The metabolic six-pack has measures that can be good markers of cholesterol disorders and if they are violated, your doctor should obtain a detailed cholesterol profile for you.

5.     There are many myths with regard to diet, exercise, fat, and cholesterol prevalent among all and particularly among Indians.  Examples of these are: (i) ghee and coconut oil are bad; (ii) lentil rich food is necessarily healthy; (iii) walking alone is sufficient as exercise.  We will examine these in later sections.

On my book, "Innovation by India for India, The Need and the Challenge"

  


Innovation by India for India, the Need and the Challenge
Author: Vaidyanathan Ramaswami

Inspired by & Dedicated to: Dr. Abdul Kalam
Recommended by: Dr. Anurag Kumar, Director, IISc., and  
  Padmabhushan Dr. V. Rajaraman, Supercomputer Research Center, IISc.
Publisher: Siksha Publications, USA
                                            ISBN: 978-0-997577-0-9

Indian edition (soft bound) available in India through amazon and flipkart



   

     Unlike many books that view India purely as a lucrative market or as a cheap R&D or manufacturing hub for foreign multinationals, this book espouses an entirely different point of view.  Its main theme is that India’s only chance of becoming developed is through innovations by Indians in India with ownership retained by them to result in businesses with novel products and services that India can use to meet its own needs and can market globally.  It proposes many specific steps towards that lofty goal.

    Books on India’s development are typically written by economists, social scientists, and management professionals.   The books written specifically on innovation deal with historical successes at the individual case level and do not cover the macro issues related to an ecology of innovation adequately based on best practices around the world.   The specific merits of this book lie in the fact that it is written by an innovator and research scientist who has had extensive international experience as faculty, industry researcher, innovator, start up manager, and strategist.  His background in statistics and macro-economics also have benefited the book as evidenced by a carefully crafted analysis of India’s foreign debt.  That analysis shows how the apparent growth of India, due primarily to its IT industry, is misleading and may indeed be one that has made the nation only “income statement rich” while becoming “balance sheet poor.” 
    
     The merits of the book have been noticed by leading scientists who have endorsed it heartily.  Among them are the Director of the venerable Indian Institute of Science and also a pioneer in computing sciences in India. 

    Above all, being written by an Indian citizen who in his own words is one “with a deep connection to India and some great debts to repay,” the book offers an optic from the standpoint of an India aspiring to join the league of developed nations.  It is in this regard that the book’s value extends beyond India to many other nations.

     The importance of India’s development is not just in the Indian interest.  As the world’s largest democracy, India’s success will have great import to the entire world as an assertion of the power of democracy as an agent of progress.  Furthermore, India’s development will increase international trade, significantly uplifting many other boats simultaneously.  Based on these facts and the significant resources for ‘making in India’ and for start-ups that India is currently allocating, the book is quite timely.

    The book is written for the non-specialist and contains much valuable data and references.

“While India has made tremendous strides economically over the last couple of decades much remains to be done. Innovation is the key, and this wise book gives us the road map. Strongly recommended.” – A reader at amazon.com

INDIAN HEALTH - PART 1 - The Indian Health Problem

This is a summary of a great book and provided as community service to you. Your feedback is appreciated.  My advice: Buy the book and use it as a constant reference.

Book: The South Asian Health Solution, 376 pages
Author: Ronesh Sinha, MD
ISBN: 978-1-939563-05-7
A video by the author Dr. Sinha: https://www.youtube.com/watch?v=3mdTTB6v94Y

Note: This summary, in my own words, is to quickly get us moving in the right direction and is not a substitute for reading the book which abounds in case studies and much greater detail than what is presented here.

The Indian Health Problem


1.     Issue: Indians, including those in the West, exhibit a higher incidence than most other groups of chronic diseases like insulin resistance, diabetes, hypertension, inflammatory diseases, arthritis, and cardio and cardio-vascular problems.  A notable number, including some who appear to be otherwise ‘normal and healthy,’ suffer catastrophes like heart attacks and strokes at ages when these are not expected.  Some even die young and suddenly due entirely to preventable causes.  As a group, Indians are seen to contract various diseases about ten years before other categories of people like Caucasians.  South Asian women have greater difficulty than men in managing their health and in combating some underlying causes like obesity. Indian children run even a higher risk than other children as they will grow into adulthood, and that alone should motivate the adults of this community to learn more about health issues, to become good role models, and to rear children with good practices with regard to issues of health.
2.     Bodily Manifestations: Indians meeting healthy norms for body measurements and lab results form a very small minority.  Most Indians are fat or obese.   The typical Indian physique is ‘non-muscular’ and ‘with chicken legs and a large belly.’   Those who don’t appear to be so are not healthy either, but are ‘skinny fat’ (exhibiting what the medical profession calls sarcopenic obesity.) Their fat is visceral, hidden inside, and attacking key parts like the liver.  The excess fat they carry and their bad fat-to-muscle and waist-to-hip ratios make Indians highly susceptible to the risks of insulin resistance, inflammation, and coagulation, which have drastic health consequences in the form of chronic diseases and even early mortality.  Indian women have a much higher incidence of PCOS (polycystic ovarian syndrome), that the author calls 'The PCOS Epidemic,' which is attributable to extra fat tissue that causes hormone imbalance.
3.    Clinical Manifestations: The following are commonly seen clinical manifestations of underlying problems: high blood pressure; high cholesterol with improper LDL to HDL cholesterol ratios; high triglyceride levels, high blood glucose levels and/or elevated A1C levels.  In more extreme cases, one also sees: thyroid deficiency; Vitamin D deficiency, and poor bone density.
4.     Causes: While inherited genetic traits and family history are important, in a vast majority of the cases, the problems are attributable directly to an unhealthy life style marked by poor/unhealthy diet, lack of exercise (and  the right type of it by those who do exercise), a sedentary lifestyle, inadequate outdoor activities, high stress, digital/blue-light overload, and lack of adequate sleep.  With respect to diet, Indians, despite their sedentary life, have continued to ingest a diet of high carbs that is suitable for the "rickshaw puller' who exerts himself much physically.  Most worsen the situation with junk and fatty and highly processed foods and snacks.  Their parties and mode of hosting do not help.  The new age Indian worker has all these exacerbated even more by junk food freely available at the work place. 
5.    Myths: The above causes are exacerbated by various myths concerning various types of foods, exercise, and dieting.  Medical science has also erred by not paying adequate attention to key measures like triglyceride levels (especially triglyceride to HDL ratio) and does not obtain detailed lipid profiles  for higher levels of type B LDL and Ox-LDL which can cause much harm .  They have focused on the simpler and non-conclusive ratio of LDL to HDL only, and brushed aside certain other anomalies as normal for Indians and not be bothered about.
6.    Good News: Much new research and clinical data shedding new light are now available that show that: (a) By adopting the right food and exercise habits and with what one would call life style changes, the younger members who do not exhibit the symptoms can prevent them altogether.  (b) A majority of those already exhibiting the cited symptoms show considerable improvement even within six months of adopting certain recommended life style changes. (c) The changes needed are not too onerous and have been developed with the clear understanding that one reason people fail to adopt change or give up too soon is due to the onerous nature of some past approaches.

GOING FORWARD: Since our goal is to move at a fast pace in the right direction, we will in the next part describe the recommended body measurements and laboratory limits specific to South Asians, and then immediately get to the recommended diet, exercise and other life style changes.  The book explains the physiology and chemistry associated with these in substantial technical detail in an accessible manner.  I believe it is important to understand those to keep our motivation high.  I will cover them in a much later part, albeit only very briefly.  Again, you must consider getting the book and studying it if not now, but at least at a later time.
