javascript - Is it possible to filter the sound from an embedded YouTube? -

is possible somehow intercept audio stream youtube video , filter it? specifically, i'd filter out high , low frequencies , compression make sound megaphone.

you'll need use javascript equalizer library, example: http://www.wavesurfer.fm/example/equalizer/

aside equalizing, you'll need audio. may able utilize service such youtube-mp3 or strip audio videos directly.
