A "beta" is the new recommended version? How will you tell in future anyone not to use beta versions until they are final?
3.90 alpha was originally recommended, and nobody complained about it. The DON'T USE ALPHA/BETA attitude is very specific in recommendations (it didn't apply to 3.90, it still doesn't apply to mppenc, and nobody is worrying about using EAC which is/was/will be in alpha, pre-beta, sub-alpha or beta stage ;) )
Though I greatly appreciate the advantages of 3.97beta I feel quite uncomfortable that 3.90.3 is running out of focus. 3.90.3 has some merits on its own especially regarding archiving quality. Personally I do not care about encoding differences which are very subtle at least to my ears, but what I really care about is about horror encodings even if they come up in rare situations. I found the worst example I ever heard in one of tha HA threads (a trumpet sample, from Don Ellis "Just One Of Those Things" as the FLAC comment says). This sample is very badly encoded with 3.96.1 and 3.97beta at aps, and is not even transparent at --preset insane).
3.90.3 behaves better at aps, and --alt-preset insane is transparent to my ears.
Using mp3 focussing on horror samples is a major issue IMO because mp3 has the great advantage compared to other formats that you can build up a hiqh quality archive which is usable without any transcoding on nearly any hardware player. But doing so having a very high degree of security a priori concerning quality is vital. (This is in its own right an important argument for using a well-established encoder version.)
While considering the beforementioned sample and how to prevent such horrible results I ran upon the --athonly option as it entirely removes the problem of artifacts created by the psy model. This surely requires using very high bitrates, but for the purpose of a universally usable high quality archive this isn't a restriction, and mobile HD players usally process mp3 files very efficiently even with high bitrates, so power drain is not too much of a problem either.
I did some abx testing with
Lame3.90.3 --alt-preset insane --athonly, and to my ears and for my samples they were transparent. Even
Lame3.90.3 -b224 --athonly results were very close to that.
Using --athonly is kind of way wavPack is going but on a widespread format basis.
As you sure have much better hearing than I have just in case you're interested: could you give --athonly a chance and figure out its merits and problems on some of your test samples? Highly appreciated are differences against
Lame3.90.3 --alt-preset insane.
