Musepack encoder version 1.16 and libmpcdec 1.2.3 are released.
libmpcdec 1.2.3 enables a new, fast method for seeking, and additionally, a seek table, the result of which is generally instant seeking. On very long tracks you will sometimes notice a delay when seeking from beginning to the end of the track. However, on consecutive seeks playback resumes instantly. On files that were encoded with an encoder older than 1.16 fast seeking is not bit-perfect. The reason is that sometimes, due to the way older encoders inject scale factors to the stream, the new seeking method may replace a very high frequency band with silence for a period of a few milliseconds and in rare cases up to a second or so. In our testing we haven't found any case where that is actually audible. Other than a theoretical very slightly different sounding output for a very short time period after seeking, there is no other artifact that can be caused by the fast seeking, so for all practical purposes it is perfectly fine on older as well as newer files. The new encoder version differs mainly in the way it injects scale factors to the stream. This enables bit perfect seeking at all times with the new decoding library. Special thanks goes to snowgoon for the initial seeking patches, R2D, for developing it further and adding features, Lefungus, for doing lots of library work, encoder patching and advising, and xmixahlx for his loads of testing, compiling, patching and support. 1.16 is probably the last SV7 encoder. All efforts are now directed at building SV8. Development can be followed on our Trac and SVN repositories. Decoder library changelog: Quote:

in addition, xmms-musepack has been updated to utilize fast-seeking with the 1.2.1 release.
the feature is a toggle in the decoder plugin options (enable/disable fast seeking). webpage: http://www.musepack.net/index.php?pg=lin tarball: http://files.musepack.net/linux/plug...-1.2.1.tar.bz2 also, rarewares/debian is updated with: libmpcdec, mppenc (musepack-encoder), and xmms-musepack later |

I want to thank r2d for joining the dev team and for his great work on the new stream version. Hannes for hosting the Musepack packages on a reliable German mirror. grimmel for hosting Musepack's TRAC/SVN and testing on FreeBSD. DEATH for his late-night work that enabled support of 1.16 on the best audio player for any OS, foobar2000. Lefungus, for his relentless passion regarding the new encoder and lots of hours of work on the lib. GenjuroXL with his mingw testing. snowgoon, for creating interest in the format again through his patches. preglow, for making MPC on RockBox a reality. xmixahlx, for his ongoing support and suggestions. Shy, for endless days and nights of working on the site and testing samples. reezeh, for the turnips

Anyone who downloaded the new encoder in the first 4 hours since its release should redownload it from the same URL. A last minute b0rkage
caused mppenc to fail with lower --quality settings. The culprit should have his head chopped by a guillotine very soon ![]() |

congratulations to all the developers, very good news
![]() I like the fast seeking, useful in partiicular with very long files! we was waiting for 1.15w, but you give us 1.16 ![]() from http://www.musepack.net/forum/viewtopic.php?p=1443#1443 Quote:
here's an addition for the software list: CUE Splitter since last release (yesterday) supports mpc splitting (first program able to do this, AFAIK) http://www.enfis.it/news.php |

Yes, the ".0" may be added by some applications. In fact, the internal Stream Version number (which has been 7.1 for years, and is now is 7.2) is not really reported to applications by the decoder, so applications may simply report it as 7 or 7.0. It's really just an aesthetic problem though
![]() Good to see that Enfis released the new version already. I've discussed with him by email lately. I'll add CUE Splitter to the program overview page. |
