Frank Klemm put up a new version 0.90i of his custom MPC encoder. No word on the changes over 0.90f, but it's a little faster for me.

This encoder is still in early development stages... use it with care and please report any bugs to [email=pfk@uni-jena.de] (use a real name and a valid e-mail address).

The two versions apparently have different speed optimizations for AMD or Pentium class processors. I'm using a PIII 850 MHz and V2 is faster for me... On first tests, i get 5.8x with V1 and 6.0x with V2.

Here's a quote from Frank Klemm off the board at http://www.chaostar.org/phorum:

QUOTE
On some machines V1 is faster (Athlon?), on other V2 (P2, P3?). 
There's currently no 3DNow! or SSE code in it, but the Athlon 
dislikes unordered memory accesses, the P3 math operations.


Although a bit OT, the good news is that if there is no 3DNow! or SSE in it, then it's likely that another fairly decent jump in speed is possible when this gets added in biggrin.gif

Silly question: What's the advantage of Fran Klemm's encoder over Buschel's mppenc?

Advantages of this Encoder:

ca. 35% faster 
support of 8 . . . 32 bit linear PCM 
can encode also encode 1 channel files and multi channel files (only first two channels are encoded) 
support of directly reading LPAC lossless compressed PCM files 
support of directly reading FLAC lossless compressed PCM files 
Can directly read from a pipe (max. 27 hours of audio possible) 
Support of WAVE files with 2...4 GByte (if file system supports this) 
some minor bug fixes (which do NOT affect audio quality) 
smoother fade in and out 
support of very verbose  -v -v
