lol 5.1 channels at 128 kbps. Good thing I never listen to english tracks and have a script that automatically muxes em out after the download finishes.
256 is minimum for transparency to source on 5.1 audio, and 128 for stereo - as concluded by tests conducted by the Audio Engineering Society. You can go lower if your source is trash and you wouldn't notice additional issues anyway - but again that's only if the source is trash.
96 kbps for stereo isn't a major sin for TV anime but it's still below minimum recs for a source that contains mastered audio and/or musical tracks.
I get this is from early 2024 but I hope you've learned something about codecs since then.
