Yep. I started work on it yesterday :)
Check out http://www.cryogen.com/mikecheng
The project is called LAME - standing for LAME Ain't an Mp3 Encoder.
It's not an encoder. It's a patch file for the iso dist 10 distribution.
LAME v1.0 patches the dist10 source to perform like 8hz-v2b-m11.
Yesterday I started work on LAME v2.0 because I read a lot of whining
around the net that the 8hz guys had wrecked the quality by speeding it
up. So I grabbed the dist10 source and patched it with most of the 8hz
and my own modifications. It's about 10% slower than LAMEv2.0, but it
produces the *exact* same output as the unmodified ISO encoder.
So for all those people saying we'd messed with the quality in speeding up
the iso code - you were wrong.
This just goes to show what you can achieve with open source and everyone
developing.
LAMEv20 still needs improving. I'd like to get it to be the same speed as
8hz-2b-m11 but with the identical output to the unmodified ISO source.
The other reason I went back to the ISO sources was that the 8hz guys took
out some of the code for mono-encoding etc.
Other projects
--------------
- parallelizing mp3 encoding. There's a bit on the web page about
parallelizing mp3 encoding, so that if you had more than one processor you
could encode at twice the speed. Read it and see what you think...
- an open source *totally free* audio compression algorithm. Something to
think about. We could just concentrate on 44khz 16bit samples and
encoding at a rate of about 128kbps. This should reduce the complexity of
the task, and produce something that the majority would be interested in.
I mean who really encodes mp3's at 16kbit/s? Or uses 32khz samples??
gotta go. supposed to be working :)
later
