This is such an amazing series! I can't believe this is free. You've put so much effort in explaining complex mathematics using such simple graphics. I know this is a series I'm going to keep coming back to. Fantastic work, Akash!
Thanks for such a detailed and beautifully animated series of videos! One possible correction on this one: At 0:29, are the units for sound pressure and sound power reversed?
Please make a tutorial video on how you make your videos, how you edit them, how you created that animation intro video with sound, how you create animated tutorials like these, etc.
I think I'll be sticking to making just videos on audio technology. There are plenty of videos on RUclips regarding this kind of animation. Keywords: Adobe After Effects, Motion graphics.
Nice course mate. But when will you upload stuff about analog and digital domain? When recording, when the level meter shows -1db what does that mean? Or when there's no input or we have absolute silence, meter shows "infinity" which in our course we understood that it should show "0 db" or some negative decibel value. What's the matter with that?
Hey man.. I'm planning to cover dBFS at some point of time. Quick answer to your question: dBFS is purely a reading of digital audio. Not analog. In digital audio, you have fixed number of states. 16bit audio let's say can store -32768 to +32767 distinct values. Since in digital audio (fixed point), no values can be stored above this, this is kept as the base line standard. So the formula for dBFS for 16bit audio is 20log(value/32768) If the value is the highest representable value (full amplitude), then 20log(1) = 0 dBFS is the theoretical maximum. Any value below that will have a negative dBFS value. And in the case of pure silence, value will be 0. In this case, 20log(0) is undefined, or if you want to represent it, tends towards negative infinity.
@@mohsens22 in the analog domain, when you are talk about level, you are talking about the voltage of the electrical signal. You can measure and compare voltage of signals using a volt meter.
Can you also do videos of the resultant(equivalent) acoustic pressure of sound wave please??...thanks again for the sharing...and the images and animations are Just great!!

Corrections:
0:26 I've interchanged the units for Sound Pressure and Sound Power
Done sir 💞
I never commented on any video on RUclips (may be Once in Million). But I cannot stop myself to comment that is GREAT WORK....
Thanks for taking the time to comment!
Take a bow Akash! This series was amazing for someone who wants to learn concepts of Audio Engineering.
Thank you very much! :) Hopefully I can continue this series soon enough..
This is such an amazing series! I can't believe this is free. You've put so much effort in explaining complex mathematics using such simple graphics. I know this is a series I'm going to keep coming back to.
Fantastic work, Akash!
Glad you enjoyed it! Hope the series treat you well over the years.
Amazing series! You broke down the topic into logical bits and then explained it with exceptional simplicity and absolute clarity. Thank you.
Cheers mate! Glad you enjoyed it..
every video is a true treasure. best regards.
Thanks so much!
great series. thx!
Beautifully illustrated and very well explained. These tutorials are fantastic and I have enjoyed watching them.
Thanks very much mate! :)
such a good series, I'll save it up
These are really good videos to comprehend the acoustic power and intensity concepts. Good visualisation of the concepts.
Thanks mate!
Thanks again for a well done and beautifully illustrated video of an often confusing subject matter.
Thank you again for the support!
Worth wise work. Respected sir
This is great stuff, Akash.
You're very good at explaining.
Thanks very much! :)
Superb series of tutorials Akash. The best I have seen on this subject. Well done and I hope you'll do more!
Thanks mate! I hope to continue this series soon.
I'm stuck on the concept of sound/energy, And it applications. Thxs for this video.
Thanks for such a detailed and beautifully animated series of videos! One possible correction on this one: At 0:29, are the units for sound pressure and sound power reversed?
Oh wow! I hadn't noticed that, you're right! Thanks for pointing that out, and for the lovely feedback!
excellent video thank you. you made things clear not only by mathematic expression, but technically as well as practically.
Cheers! Glad you found it useful!
cant wait for part 6 jajaja, huge thanks
Finally done sir , Thankyou for you efforts
You're welcome! :)

@@akashmurthy Thank you! Excellent response!
But how is this "level" thing is calculated and quantified in the analog domain?

@@akashmurthy Thank you mate!
Great Video mate 👏
Thank you!
great stuff
Best vid on this topic
Thank you!
Can you also do videos of the resultant(equivalent) acoustic pressure of sound wave please??...thanks again for the sharing...and the images and animations are Just great!!
Hey there, thanks for that! There is a video on Sound Pressure on my channel, check it out!
hello sir. Have you done videos on A weighting measurements? I'm working on an arduino project and i can't find much online. thanks for these videos!
You're welcome! I'm planning to cover A, K weighting at some point of time.
Thankyou So much...
Can you do videos on building acoustics please??
That's not my area of expertise, I'm afraid.
Thanks a lot for thé sharing
You are welcome!
Good Job
thanks akash
You're welcome mate
I'm not the legend, You are.
