is there a way to record audio in mp4 using ruby on rails / web / html5 -


i find way record audio (not video) in mp4 format on web.

reason ios/android both generating in format, , want able consistent audio format. (android mediarecorder example not mp3, thats reason why preferred format)

is there recorder records mp4 audio web/html5/rails?

update:

i found out recorderjs https://github.com/mattdiamond/recorderjs

im guessing if change encodewav encodempeg4 in here: https://webaudiodemos.appspot.com/audiorecorder/js/recorderjs/recorderworker.js

this target audio outcome im trying achieve:

type: audio

codec: mpeg aac audio (mp4a)

there example uses web audio api. think front-end(html , javascript) should handle audio recording generate mp4 file can save in rails app via carrierwave or else.
