Musepack SV8 has been finalized and the first stable release is out. The new stream version offers many improvements over SV7, to users and application developers alike.
Changes: - Container-independent format. An SV8 MPC is a container file for a Musepack stream. Raw stream encoding is possible. - Packetized stream allows muxing into audio and video containers (e.g. MKA, MKV, NUT) - Sample-accurate, fast seeking independent of file length - Sample-accurate cutting - Chapters - No internal clipping. --noxlevel flag removed, not needed anymore - Bitstream compressed by highly optimized canonical huffman tables - 2% smaller files and faster decoding - Streamable - Cleaned up and rearranged code - libmpcdec, libmpcenc, libmpcpsy Package contents: mpcenc - Musepack SV8 encoder. Accepts WAV and lossless source files. mpcdec - Musepack SV8 decoder. Decodes MPC to WAV or checks for stream errors. mpcgain - ReplayGain calculator using our new ReplayGain library. mpcchap - SV8 chapter editor, for embedding chapters into MPC files using info in chapterfile.ini or cue files. mpccut - SV8 stream cutter, for losslessly cutting stream segments based on selected start/end samples. mpc2sv8 - Musepack SV7 to SV8 converter. Losslessly converts MPC files encoded by an SV7 encoder. SV8 specification Special thanks to: Nicolas Botti, the main person behind SV8 development, for a massive amount of work during a period of several years. Peter Pawlowski, for important performance and stability related contributions. grimmel, for SVN and Trac maintenance and hosting. Genju, for non-stop binary compilations, testing and support. Igor Janos / MONOGRAM, for SV8 DirectShow decoder and splitter development, and support. Andree Buschmann, for code optimizations through his Rockbox efforts, and everyone who contributed patches, offered advice and helped make the format stable and robust. Download: Windows package Linux package Source code Windows users can use the latest foobar2000 which already fully supports SV8's features. While SV8 outperforms SV7, it's not yet as widely supported, as it is newly released. If you have SV7 files, make sure your application/s supports the new version before converting to SV8 and deleting SV7 files. |

Cool news indeed ! Many thanks to the musepack devs !
Since Nullsoft's Winamp plugin will be updated by them in eons, and I'm not a developer, I'm asking if someone here intends to make one. |

Fixes to reported bugs are in the latest SVN build
mpccut will work even on broken files. mpcgain and mpc2sv8 will too. Pay attention to ANY "An error occured while decoding, this file may be corrupted" message from mpc2sv8. It means the converted file was partially broken |

I thought I'd put a sign of life out there. Here are Windows binaries of the latest SVN revision (477) in 32 and 64 bit flavors:
http://negju.musepack.net/sv8_r477_gcc_x86.7z (32 bit) http://negju.musepack.net/sv8_r477_gcc_x86-64.7z (64 bit) |

Thank you very much!
May I ask you about both libraries in the pack, libcuefile.dll and libreplaygain.dll. Should I place in the system32 directory or in the program directory? And, what does wavcmp do? |

Firstly, you're welcome! Secondly, put those two DLLs either in the same folder as the executable files or somewhere else in your system's %PATH%.
Wavcmp does pretty much what its name says, it compares two .wav files and prints out the differences if there are any. ![]() Edit: If you want to run both 32 and 64 bit versions side by side, it's probably a good idea to keep the DLLs right with the EXEs. Note that this isn't recommended, just pick the one that's best suited for your operating system. |

Thank you for your reply.
It seems that mpc2sv8 don't work for me. Is it possible that this is a compile only for AMD? I'm sorry I cannot copy the whole dump that windows raised, this is just the beginning... http://ant0nski.hit.bg/temp/mpc2sv8_er.jpg The original version from 2009-02-24 is working fine. |

Please note that these recent SVN mpcenc builds shouldn't be used for encoding since at the moment it seems some files may have a problem (it may just be mpcdec-related). I'm sorry if some people were affected by this, I should have mentioned again that people should only use the official builds available on the main site if you want to be certain that everything will work properly.
We'll also have to check what's up with mpc2sv8 and so on, so if you use any other SVN builds or make your own from any version not marked as "stable", please don't use any of the tools for anything except for testing and reporting problems or feedback. Edit: no encoder bug, just decoder. Newer test builds (r481) here: 32-bit | 64-bit |

See above edited post for newer test builds. (fixed decoder bug and raw streaming enabled)

Hi,
I'm afraid the mpc2sv8 is broken in r481 too. It succeeded to write only 46 bytes in the output file. So I unpacked again the original exe from 2009. This is the content of output file produced: Code:
4D 50 43 4B 53 48 0F 04 50 80 20 08 85 B5 C6 1C 00 1E 1B 52 47 0C 01 48 BD 5B 6A 48 BD 5B 6A 45 49 07 C0 01 0E 00 53 4F 08 00 00 00 00 00 ~~ |

What's new in these versions? Are they affecting audio quality? Where can I find a changelog?
Thanks. |

The newer source code mostly has improvements for developers. Most of the tools (like the encoder) have no changes. A notable new feature for end-users is raw streaming in mpcdec to improve support in things like Squeezebox.
Changes are detailed in SVN revisions (viewable with an SVN client). The next time we release a non-"test build" package on the site, we'll summarize a change log (like this). |
