Hi,
I have task of recording webrtc local stream audio and webrtc remote stream
audio.
I succeeded in recording audio with MediaRecorder (using timeSlice) in which I
get recorder chunk Blob (audio/ogg) for local and remote audio.
Now, before I send this to server I would like to mix recorded local and remote
audio chunks to one chunk using Web Audio API and this is where I have some
problems.
I used this steps:
1. when both local and remote audio blobs are available I'm using
FileReader to get ArrayBuffer for each
2. using AudioContext decodeData to get AudioBuffer (here I get error: The
buffer passed to decodeAudioData contains an unknown content type. and The
buffer passed to decodeAudioData contains invalid content which cannot be
decoded successfully.)
3. then I thought I can use OfflineAudioContext to connect both AudioBuffer
to OfflineAudioContext destination and get AudioBuffer mix. Is this OK?
4. After OfflineAudioContext rendering is done I need to convert
AudioBuffer back to Blob so I can get Data URL using File Reader to sent to
server. How get Blob from AudioBuffer.
Please help,
Thank You
