|Convert MPC to MP3 and other music format in one click!
The beauty of using 4Musics MPC to MP3 Converter is that
it works from the right click menu on a file. You do not have to
invoke a whole other program to to convert MPC to MP3, WMA, OGG, WAV, M4A,
AAC, Flac, AMR_WB,
MP2, AC3, AIFF MMF.
Simply right click on the MPC, select "Convert to MP3"!
As easy as 1, 2, 3!
What is a MPC (Musepack)? The psychoacoustic
model of MPC is based on MPEG ISO model 2, but is extended by CVD
(clear voice detection). The quantization algorithm of the MPC
encoder performs spectral shaping of the noise, called adaptive
noise shaping (ANS), in order to overcome the low frequency
resolution of the
polyphase quadrature filter bands.
In the past, MPC has been under suspicion of violating multiple
patents (MP2, PNS, subband) . According to the developers of MPC,
all patented code has been removed and it is now believed to be free
of patent encumbrance. However, one PNS patent application is still
active, and it is not trivial to know if MPC's own "noise
substitution techniques" avoid its scope or not. Only a careful
examination by a patent lawyer would say whether Musepack is truly
patentless or not.
MPC uses the APEv2 tag metadata container.
Musepack is mainly optimized for transparent encoding at the
"--standard" preset (175-185 kbit/s). Very few optimisations have
been made at lower bitrates (like 128 kbit/s). Nevertheless, various
listening tests have been conducted in which Musepack has performed
well at both lower and higher bitrates.
