OptimFROG is a lossless audio compressor. Here are the improvements of the new version:
- again, another up to 100% faster operation on modern
processors, and up to 270% on older ones, with the same
results
- new buffering scheme for faster disk operation
- Linux version with same functionality and speed as the
Win32 version
- full pipe support under both Win32 and Linux
- added seek support option for compressed files
- Winamp™ input plug-in for real-time decoding
- OptimFROG will now completely replace FROG
- fine-tuned the compression engine
- fixed some slowdown problems in the compression engine
- new "best" mode (4) for benchmarking
- removed stereo mode option, using automatic settings
- graphic percentage display

Did you say faster, with a WinAmp plugin? For me those are the magic words for OptimFrog. Awesome news! I'm working on a drop frontend for Frog right now. Ghido rocks!

I want it at my site. : D

How does this compressor compare to other lossless compressors like Monkey's and LPAC?(Some tests or comparisons) Also, is there an XMMS plugin?

Hmm, I wonder if this can be implemented also for example to MPC..

Highest compression available. Bar none.

Take care, the format is not stable:

"OptimFROG42Win32.ZIP 65196 bytes / CRC32 82E40B11
(take care, the compressed format for 4.2 is incompatible with 4.1)".

See my comparison of lossless encoders: http://home.wanadoo.nl/~w.speek/comparison.htm

About OptimFrog4.2: for better compression (also better than Monkey's extra-high) use no-seek, mode 4 and speedup 2 or 4, example:

optimfrog a input.wav output.ofr 4 2

Layer3Maniac....How bout a frontend for OptimFrog called FROGDrop? It looks like there is only an executable and the format is really nice. What do you think?

I made a frontend for OptimFROG. It's called Kermit.http://home.wanadoo.nl/~w.speek/kermit.htm
