Some things are still not clear to me regarding SPDIF.
AFAIK SPDIF allows
1) 2 Channel Stereo PCM
2) Frequencies of 32kHz, 44.1kHz and 48kHz.
3) Any compressed multichannel audio format equaling the bitrate of uncompressed stereo 16-bit PCM bitrate, which taking into account statement #2 gives 1024kbps, 1411.2kbps and 1536kbps.
Questions
1) Are there any constraints on bit depth of Stereo PCM?
2) Its impossible to send audio signals higher in bitrate than Stereo PCM, but what about lower bitrates? Is that impossible too? Or does it have to be exactly equal to 16 bit Stereo PCM?
