Multichannel Audio Recording
Posted: Mon Dec 21, 2020 10:55 am
At the moment SDR Console can "Record Active Receiver" to a standard WAV, WMA or MP3.
I would be very interested in a feature allowing me to make a synchronised recording of two RX simultaneously (say one RX to Left, the other to Right). This would be used for monitoring broadcast stations on parallel channels, and have the double benefit of reviewing a session for periods of clear overlapping reception plus submitting clips in a single file as evidence.
Why stop at two? In principle, a monitoring session could be expanded to a large number of audio streams and not limited to just parallel broadcast channels. The WAV format can theoretically handle up to 64K channels, and there is player/editor software available to review and edit individual channels or combinations. (I realise the monitored channels would need to be within the same sampled bandwidth.)
The only downside is that MP3 compression is not available for more than 2 channels. WMA has the same limitation, although WMA Pro can handle 8 channels. That would not be a problem for me.
Would it be possible to include periodic timestamp metadata, rather than rely on file title? I've not looked at this for several years and cannot remember how you managed it for I-Q recordings.
