FLAC 1.3.4 - Hackdot

Re:FLAC 1.3.4 by namibj on Wednesday February 23, 2022 @04:18AM (#30439250)

Both FLAC and Opus[0][1] have a dial to trade efficiency against CPU time. Have you even tried? I doubt FLAC remains a superior choice at low-complexity Opus settings. The library also has a complexity setting for the encoder.

[0] https://opus-codec.org/docs/opus-tools/opusenc.html [1] > Set encoding computational complexity (0–10, default: 10). Zero gives the fastest encodes but lower quality, while 10 gives the highest quality but slower encoding.

I have tried it. It works, but the difference in my experience isn't a huge one.

Complexity 0 is about twice as fast as 10. Which isn't bad, but if you want to go really fast it still leaves something to be desired.

I hope this has been measured with the binary optimized for the CPU architecture in question, in oder to sqeeze out reasonable gains from likely more portability-focused opus code, particularly regarding vectorization opportunities.
