I found that in my (high quality) studio monitors, the audio sounded fine and hard to distinguish from 24kHz wav. But in headphones, the artifacts were pretty obvious. So probably some reverberation will do a lot to cover up artifacts. In the paper, they only do a subjective comparison between the generated audio and the soundstream-encoded original audio, which seems a bit disingenuous. Listening to soundstream audio in headphones, I can hear those same artifacts.
