Seems on C3 is possible, but wonder if there is anyway via plugin to do the same in C2.
So you can record and save the sound in various formats with X bitrate,etc...
"ffmpeg webassembly" comes already in construct3.
they're using ffmpeg via webworker to do what you want. convert to mp3,option bitrate etc...
but since construct2 does not have "webworker" support...
