you can use AmAudioQueue (AmAdvancedAudio.h) to write audio to two
AmAudio devices.
put both the audio_connector and the AmAudioFile in the write queue,
and it will write to both. You don't even have to modify the
AmAudioConnector, you just catch the b2abconnectaudio event, and after
it is connected, you get the output with getOutput() and put it in the
queue, like
MySession::onB2ABEvent(ev) {
AmB2ABCallerSession::onB2ABEvent(ev);
if (ev-event-id==B2ABConnectAudio) {
lockAudio();
audio_queue.pushAudio(getOutput(), AmAudioQueue::OutputQueue,
AmAudioQueue::Back, true, false);
audio_queue.pushAudio(my_audio_file, AmAudioQueue::OutputQueue,
AmAudioQueue::Back, true, false);
setOutput(audio_queue);
unlockAudio();
}
i've done some testing with the AmAudioQueue alone...
So, when i use it to write to the connector and a file (each leg to
diffrent file) everything works fine - but unfortunately i have two not
mixed files :P
I've even tried to push the same AmAudioFile object, to both queues to
get both streams in one file, but that was obviusly stupid - a lot of
sync problems, and the output audio file was full of strange noise. I
assume that we have to use some "syncing device" like an
AmMultiPartyMixer used in AmConferenceChannel - but then we're getting
AmAudio object with mixed stream - it is easy to use it to feed another
(third) session, but how to use it to write the mixed stream ?
