For what application do you need 96kHz or 192kHz of bandwidth?

Good old FM radio (in stereo) is a 192kHz mux, annoyingly.

How so?

Stereo pair, pilot, RDS (the scrolling artist/song text), and the 67 kHz SCA. It's not quite 192kHz as I recall, but that's nearest fit really. AES192/192kHz MPX composite on the back end of every exciter/transmitter when I was last near them.

That's for the FM baseband signal, not the audio. Among other things you're doing here, you're basically treating a stereo signal (plus a pilot that effectively contains no information, plus an extremely low bitrate RDS stream in an extremely inefficient way) as one monaural signal.

But maybe there's a use case for replacing an AES192 signal carrying the full FM baseband signal over ETH-67? I'm not sure it's the correct fit, though.

		That's how radio works now, it's owned by like 3 companies. Automation/playout for large groups of stations is all centralized, and they carry the baseband over IP to transmitter. Radio solved it awhile ago. https://www.telosalliance.com/radio-processing/audio-interfa... etc.

Tuning into time radio signals like DCF77?

Distributing music != recording music != processing music.

There ARE good reasons for recording and processing music at higher bitrates and sample sizes. Effects, especially those with positive feedback loops, can go more unstable and clip and lose information with fewer bits and samples.

There's just no good reason to DISTRIBUTE music at the higher rates.

		Don't such effects already upsample and downsample as needed internally ? You don't need to waste cpu on the effects that don't need higher sampling rate, right ?
