Listening Tests / Re: Personal blind sound quality comparison of xHE-AAC, Ogg Vorbis, and TSAC
Last post by C.R.Helmrich -- In your earlier (09/2020) tests (https://hydrogenaud.io/index.php/topic,119861.0.html), exhale 1.0.6 reached a mean score of "only" 4.47 on the same 15 samples. It's nice to have some evidence now that exhale's higher-rate audio quality improved some more during the last 3-4 years.
- Regarding my score estimator (https://hydrogenaud.io/index.php/topic,118888.msg989150.html#msg989150), your average results from yesterday are now above my estimate, similar to IgorC' 2020 results at 192 kbps. Maybe I can finally update my score estimator at the higher rates
- AFAIR, this is the first blind test in which a machine learned end-to-end codec is compared against high-performance classical audio codecs. This is very valuable information since it puts all these "AI codecs outperform MP3" hyped claims into perspective - machine learned codecs deliver decent audio quality, but they don't scale to transparency... at least not in 2024.
