Mobile Media Capture - Audio Option

Hello there,

I am using phones for data collection and would love to use mobile media capture - but instead of video or photo, I would like to use the audio option. Something like this:
id="capture"
accept="audio/*"
capture />

Is there anyway to add the audio option and remove the photo/video?
I have tried using PIPE, but it doesn't work with mobiles this way either. Only on computers.

Thank you!
