MP3 - Tech / Re: Current status of MP3 encoders
Last post by darkalex -Pardon, but aren't these those killer, hard-to-encode samples, and not real life music?These were indeed hard-to-encode samples and at the same time they are real life music. Nos synthetic frequency sweeps. Still, these were killer samples for MP3 (at least for V2) but not so for AAC.
Still I agree with you that "aac easily beats mp3" at 256 kbps is exageration. It's well accepted here that LAME V2 (192 kbps) produces transparent results for wide public. So it's ok if some well trained listeners like Kamedo2, IgorC, Guruboolez can perform blind tests at higher bitrates.
Yet there is strong evidence that AAC 96 kbps outperforms MP3 128 kbps https://listening-test.coresv.net/results.htm
Kamedo2 tests also confirm that AAC 192 is better than LAME MP3 192 kbps, but again he is extremely trained listener.
https://kamedo2.hatenablog.jp/entry/20111029/1319840519It might be time for organizing public ABX testing, we do have some new codecs.Where?
I can see only two xHE-AAC encoders (exhale and Poikosoft/FhG) and their popularity is still low.
- MP3 - Lame/Helix. No quality changes since last public tests
- AAC - Apple is still the best AAC encoder already for 20 years
- Aotuv Vorbis, Musepack - no change
- Opus - no change, except speech quality at very low bitrate, I don't think here folks will be too excited to test it at that low bitrate.
I'm not the kind to pick up my daw and start ABX'ing rn because I'm a bit too occupied to do that all for proving my point, but I can assure you, that a few years ago when I had not much idea about AAC/MP3 encoding or what I preferred (back then it was all about compatiblity and not necessarily "choice")
I always went with AAC except in situations where AAC won't run on the device... in my hifi system as well, my chain is transparent class AB, feeding from my foobar straight to the DAC exclusively, AAC always sounds better... just like the public tests confirm...
Apple AAC - the best
The point being, it's been 20 years since that encoder came, and more like 15 years since it has had no updates... and I find it very hard to believe that it can't be improved further with the tech we have today... it's just not reasonable yk?
PCM is decades old yes I know, but it's not a model, it's uncompressed... this is compression and psychoacoustic modelling... and it's kinda hard to believe that AAC or MP3 can't be improved further...
We may be 98% there, but there's still a 2% chance I believe in, especially for MP3... don't quote me on the 2% etc numbers, they're pulled out of air just to express my point, but ykwim..
We have AoTuV for Ogg... maybe something like this for LAME?
