Thanks wbartels for Your reply.
I think I have enough bandwidth because I streams files locally.
I have web server on Windows XP SP3.
Apache/2.2.11 (Win32)
PHP/5.2.8
MySQL: 5.0.51a
PHP memory_limit = 500M
I have latest winamp version 5.572 and in_wv.dll version 2.8a but winamp do not streaming wavpack files. I don't know if it is problem with my winamp or simply it can't stream wavpacks. Are you able to check if Your winamp can stream these files?
I have also foobar 1.0 installed. It streams wavpacks

but I noticed that it streams wavpacks correctly in lossless mode only. When I streaming wavpacks in hybrid lossy mode, foobar shows the bitrate of the file incorrectly (more than it really has [i think bitrate x2], for example: my file has 320 kbps and foobar, when I streaming it, shows 640 kbps), and plays it with hangs up (sound stops for half second, CPU usage increase for APACHE process [probably buffering] and then plays it further). Check waveform below to see what I mean:

I hope this problem will be solved in the future releases of foobar and winamp.
Thanks.
