iOS Custom Audio(Data) Source

[Orgest Blakçori]

Hi,

In our iOS app, we have integrated a stethoscope iot device, that returns continuous audio data. I'm trying to get add those data on audio track of webrtc instead of my mic.

I do not see any documentation related to that. I am aware that i have to modify native code but some starting point would be really helpful.

Hi,

As an option, you could implement custom audio device (RTCAudioDevice) and override default one over RTCPeerConnectionFactory

RTCPeerConnectionFactory 

/* Initialize object with injectable video encoder/decoder factories and injectable ADM */

- (instancetype)

    initWithEncoderFactory:(nullable id<RTC_OBJC_TYPE(RTCVideoEncoderFactory)>)encoderFactory

            decoderFactory:(nullable id<RTC_OBJC_TYPE(RTCVideoDecoderFactory)>)decoderFactory

               audioDevice:(nullable id<RTC_OBJC_TYPE(RTCAudioDevice)>)audioDevice; 

And use deliverRecordedData to feed outgoing audio track with your data.

Also be sure you have set "send" audio over SDP offer with corresponding audio options.

Best Regards, Maxim.
