I note that a certain pet bird has the signature line
QUOTE
WavPack (352/448 kbps) lossy for HQ lossy encodings and transcoding
LAME 3.90.2 (by Dibrom) --alt-preset extreme -Z --lowpass 21 or --alt-preset insane --lowpass 21 for my mp3s
MP2 384 kbps stereo for the classical music on my portable
MusePack 1.15r --insane --xlevel for archiving on CDs


Is he right in using WavPack, as opposed to MPC?

Something tells me the higher the bitrate, the more he likes it - There isn't an MP2 encoder as well tuned as Lame, and cranking the bitrate up to 384 isnt going to make the encoder more 'tuned'. And MPC insane / MP3 APX are virtually unnecessary overkills too; YMMV.

2. I followed your previous comment and revised my signature.  B)

Great. smile.gif

Have completed some other follow up tests with a wide range of ambient and punchy pop/rock, focusing only on mpc beyond braindead, LAME insane and Ogg Vorbis q10. Found artifacts in all cases to varying degrees if I listen hard enough when they are transcoded into ATRAC3 (Minidisc). LAME and Ogg Vorbis were considerable worse than MPC in terms of introduced artifacts with transcoding, but all three were not too bad.


Excellent. That's a proof of the theory that subband codecs (MPC, MP2) behave better than transform codecs (MP3, AAC, Vorbis) when being transcoded.

Dunno about others' opinions, but I find these findings extremely significative. Before, people only said "theoretically, transform is worse than subband for transcoding". Now, we can be almost completely sure that theory applies to practice. smile.gif

has anyone ever compiled a Linux version from your source code? I'm currently considering setting up a Linux box for audio encoding, storage and serving purposes.


Actually, would you know anything about C programming, by any chance?

David is looking for someone to port WavPack to Linux. Should be really easy, because the code is 100% ANSI C. Still, some coding will be needed.

Hopefully, some linux code will be available soon.

Regards;

Roberto.
