Hello!
The problem is that i`ve tried to encode a wav file with sampling rate of 48kHz. The result was in 41.1 and the plaing speed was slow. Is the a way to encode such files without previous resampling? Thank you.

from what i know, when you rip a CD to wav your just copying the CD audio file into a .wav container on your hard disk. You computer does nothing but read and write bit for bit, no encoding happens when you rip to wav. What you might want to try is encode to FLAC at 48khz then back to wav? I dont know if that would work though.

That is strange... I just encoded a 48 KHz PCM Wave file with the MusePack 1.14 encoder and everything worked fine.

Yes, that`s strange... With Lame and Ogg everything goes OK. But with Musepack 1.14 it doesn`t work... I don`t grab CDs, I just make records myself and don`t want to resample them...

I found out, that the problem is in WinAmp5&2. Windows Media Player plays encoded 48 kHz MPC file just fine. Don`t know what to think...

Are you using version 0.99d of the WinAmp MPC input plugin?
I had no problems encoding a 48KHz WAV and playing back the resulting 48KHz MPC in WinAmp.

I found another decoder was installed in WinAmp(in mpp.dll). I removed it and everithing is fine now. Thanks everyone for the answers.

no problems with foobar2000 v0.8 and 24 bit / 48 kHz waves to flac and later those flac to 24/48 MPC 1.14.

I have recorded a nice Jazz-Big-Band Vinyl of mine via terratec ewx 2496 to my pc some time ago.
Just for curiousness I played around with 96 kHz, and saw, that foobar/flac compresses 24/96 waves, no problems, but MPC 1.14 could not compress 24/96.

From what I can see in source, MPC SV7.1 supports only 44100Hz, 48000Hz, 37800Hz and 32000Hz.
