Optimfrog Update

From the OptimFrog website:

19 Oct 2002
After a long period of absence, being very busy with faculty, job and health problems, a new alpha version of OptimFROG is almost ready. It has significant compression enhancements, support for all integer PCM WAVE formats up to 32 bits, multichannel audio, RAW data, ID3v1 and ID3v2 tagging, CRC32 error checking, error correction, and large (64 bits) file support. All these are based on a new extensible compressed format, making very easy to incorporate additional file formats, algorithm improvements, and additional data without breaking backwards compatibility. I intend to add an asymmetrical OptimFROG algorithm variant, where decoding (playback) will be much faster than encoding, at only a slight degradation in compression performance, and (!) support for Cool Edit/IEEE float (32 bits) format. There will be also bugfix releases for the current 4.21 series.

Maybe he changed it because it's alpha.
It's probably not very recommended to use this version, it's still just *alpha*, so you better keep your front end as it is

It doesnt really matter.  The amount of bugs in my front end program are unimaginable.

The 4.50alpha files don't play in winamp here ("not a valid optimFROG file") so I suppose an updated plugin will come soon. Optimfrog website is down now.

Meanwhile I updated the graphs here already, but not yet the ones in the LA 0.3 thread (for comparison).

You needn't worry about updating the graph with the new 0.3x versions - the compression hasn't changed at all (except a bug fix which shouldn't make a difference), and i haven't made any speed improvements either. if i make any changes to the compression then i'll bump it up to 0.4. however i want to get it nice and stable, sorting out any remaining issues with the linux version etc first.

Yes Michael, I noticed compression or speed didn't change with 0.3c.
I just made the graph's legend up to date with this preferred version, while changing it anyway.
