Comment on TSAC: Low Bitrate Audio Compressionparent

Comments

I think the big use case is satellite telephony and satellite radio/audio/podcast play. You could do all audio applications off a 3KBit/s connection - that’s completely insane.

It would probably have to be optimized a bit further though, both in terms of computing as well as size. Goal would probably be real time encoding on an iPhone SE without breaking too much of a sweat, and a encoder/decoder perhaps less than 200MB?

I am curious how well this does work with a full orchestra music — that’s where encoders usually croak. Give me a sample of the Star Wars theme.

How does satellite telephony work? Alice calls Bob over satellite. Alice's telephone is on AC power, and contains a GPU cluster, and Bob's is the same?

Today's GPU clusters is tomorrow's cell phone. But this codec doesn't require that much power anyway. I didn't try it but on some forum somebody claimed 0.5x speed on a Core(TM) i3-7100U CPU @ 2.40GHz [1]. It sounds plausible that with some more optimization and a bit better hardware, that's a bit more specialized for AI, it could do real time encoding and decoding on cell phones.

I remember playing OPUS files at 16 KBPS over a... 2G? connection with mplayer's caching options. The audio sounded a bit better than MP3@32 or Real Audio back in the day.

As the music was "avant gardé", it almost fitted the genre.
