Lame 3.93 released

[bond]

Known bugs:
- the fast presets can produce mp3s with a higher bitrate than the non fast presets (will be fixed in the next release)
- history.html lists "3.93alpha" instead of "3.93"

We will release a new beta version soon, it will contain a high amount of code changes. If you just want to have good MP3s, you should stay with this release for a while, the upcoming beta version if for testers only.

In the name of the LAME development team I wish you much fun with this release.

Greetings,
Alexander Leidinger.

btw it is not recommended to use 3.93 with --alt-presets!
The sound quality isnt tested very much until now

if anyone still feel like experimenting, you should know that latest beta of BeSweet had been tested succesfuly with 3.93.

edit :
i'm naturally talking about the uncommon switches that needed a special dll build for BeSweet and now working with the official build :
-x --scale --noath --athlower --noshort --lowpass --athshort --athtype -Y --nspsytune --nssafejoint --ns-bass --ns-alto --ns-treble


and more...

for sure :D

we have a new preset (not created by Dibrom, but based on APS):
--preset medium

I believe the status of the --preset (formerly --alt-preset)s is that there isn't much change in 3.93, but it is not yet thoroughly tested. Last I read, the "fast" versions of the presets were having some troubles, but perhaps these have been fixed in 3.93...testing and time will tell....i'm very looking forward to 3.94 and --nspsytune2

The problem with "fast standard" is related to bitrate only: The bitrate can be too high.

Where is ACM version of LAME codec 3.93???
I want use this in vdub.
