One line version:
What open source software (WAMI-Recorder)/web browser (via getUserMedia) will give me the best quality audio recordings?
High quality would be defined as (44.1 or 48 sample rate) and 16 bit sample size.
More Information:
So currently my solution is WAMI-Recorder, but I am wondering if the HTML5 specification has matured to a point in browser such that I can record without Flash and get equal or higher quality audio recordings. Currently it looks like WAMI maxes out at 22050.
I do not need cross browser support as this is for internal business use.
A non-Flash solution would also be preferred.
I found something here. hope it will help you to record audio
