Hello I tried to change sample rate and number of channels from audio session by using setPreferredSampleRate and setPreferredInputNumberOfChannels. Does the sample rate at 44,1 kHz really matter or 48 kHz may be supported for spatial recording? Should I use other API since it still fail to have MXSessionMode = SpatialRecording ? Best regards

Need to use appropriate timescale for timecode sample buffer duration and patch timecode sample buffer presentation timestamp with first presentation timestamp of video track.
