Seems to me you can implement option 1 using Web Audio: create two MediaStreamAudioSourceNodes, one for the local and one for the remote audio MediaStreams, mix them together as the input to a MediaStreamAudioDestinationNode, feed that node's MediaStream into a MediaRecorder using the timeSlice option, and send the resulting Blobs of compressed audio to the server. The server can then concatenate the Blobs to get a complete resource that can be decompressed later.
