Hi,
Since now, Hydrogenaudio.org is recommending that all people providing test samples will use open source FLAC-format for lossless compression. LPAC, which has been used quite a lot, is totally closed, and there are no decompressors for every platform which people use here. I will be converting the samples I host to FLAC and edit the links in corresponding messages. I've also contacted ff123 and he has agreed to change to FLAC-format. FLAC-homepage: http://flac.sourceforge.net/ FLAC-download page: http://flac.sourceforge.net/download.html All releases: http://sourceforge.net/project/showfiles.php?group_id=13478 Win32 compressor, frontend, winamp plugin -bundle: http://www.inf.ufpr.br/~rja00/files/FLACbundle.zip Win32 FlacDrop-frontend: http://www.inf.ufpr.br/~rja00/files/flacdrop.zip Command line usage: To compress: flac -8 test.wav To decompress: flac -d test.flac Latest versions: Win32: http://prdownloads.sourceforge.net/flac/flac-1.0.2-win.zip Linux-i386: http://prdownloads.sourceforge.net/flac/fl...rh7-i386.tar.gz Darwin PPC: http://prdownloads.sourceforge.net/flac/fl...rwin-ppc.tar.gz Solaris: http://prdownloads.sourceforge.net/flac/fl....7-sparc.tar.gz Debian packages: http://packages.debian.org/cgi-bin/search_...all&release=all Source: http://prdownloads.sourceforge.net/flac/fl....0.2-src.tar.gz Sure, FLAC may not have the best compression ratio, but it shouldn't matter in case of relatively small test samples. More important is that because of open source, it's equal for all people using different systems. Of course if a test clip is purely for win32 encoder (Psytel AAC), there's no compatibility reason to compress with FLAC, but chance is a test clip can be problematic with several encoders. That's why Hydrogenaudio.org is trying to push FLAC as the lossless compressor of choise for test clips. 
Thanks. -------------------- Juha Laaksonheimo

Well, I may be having second thoughts. It would be so much nicer if there were a flacdrop which could encode/decode without the command line.
There's a Monkey's Audio gui hack which works ok for encoding, but is not good at all for decoding. Plus, it took me half an hour to figure out how to get it to encode from within MA. Not a good solution at all. How about this: I'll switch when a flacdrop exists which can both encode and decode. ff123 |

Thanks Agent69! I use RAD Pascal (Delphi, specifically). It's perfect for little apps like this, no runtime files & no dll version hassles. Just a standalone executable.

Maybe layer3 can provide us a FLACdrop.

Why open source?
Can't you link to it in closed source state? -------------------- Get up-to-date binaries of Lame, AAC, Vorbis and much more at RareWares:

Layer3:
You did a great job on the aacenc frontend and the FLAC one will be appreciated as well. Question: What are you using to program these frontend tools? Thanks. |
