I think you NEED to read a book on the BASICS OF ACOUSTICS (for audio). You should take a moment to actually listen to this video to try to make yourself aware of how much room echo is present at your piece-of-shit microphone. This presentation SUCKS !
Thanks for the Knowledge. While explaining on how to take the values for various modulating conditions, it would have been better if you explained it (on how to take the Max and Min Values) by a simple drawing on paper. As in the video the waveform is not stable and also not so clear. Please consider this for future videos. Once again, Thanks so much Sir.
