For those who are interested in checking out my initial specification for the FlacPak format, I updated the web pages at: http://swami.sourceforge.net/flacpak.php The direct link to the specification notes: http://swami.sourceforge.net/flacpak_format.php For those who weren't reading the previous threads, FlacPak is a format being designed to handle compression of files contai...

Thought I'd send an update on FlacPak a file format for compressing instrument files (although its more generically a method of compressing files containing binary and audio with most of the smarts being in the encoder file handlers). It uses zlib for compressing the binary data and FLAC (of course :) for compressing the audio. There i...

...a quick mini banner logo based on the flac logo and put it up for viewing (its not publicly linked yet). Let me know if this is ok with you, or if you would rather me come up with something original :) My only complaint about it, is that I like the font you used better. http://swami.sourceforge.net/flacpak.php Cheers.

...e number of samples as you encoded? The problem with looping arises if the loop points aren't the same sample values, resulting in a click. Some sort of algorithm could be run around the loop points to get them to align again, but I wouldn't know the best way to do that, yet. The purpose of FlacPak is to be able to compress existing sampler formats that contain binary and audio data. Many of these formats also contain stereo samples, but separated into individual mono samples. The encoder will have knowledge of the format it is compressing and will be able to exploit split stereo samples, etc...

...othing more annoying then downloading a zip or rar instrument file only to find it has also been compressed with sfark or sfpack. I guess the sfark people deserve some credit, they have at least been promising a Linux client for a few years now (still no sign of it though). I was thinking of making FlacPak associated with flac (seems appropriate since flac will be the primary technology used in the format), so I was wondering about basing the FlacPak logo on the one found on the flac web site (with the green/yellow/red level meter bars). How do you feel about this? Any graphics I come up with in this...

...to finalizing the specification for that project, and I have since realized that a more generic approach would be better. I registered the "SFFL" Sound Font FLAC application meta data ID. I would like to remove that, since it was never actually used, and create a new one "FLPK" FlacPak. This format will be a generic way to compress files containing audio and binary data (files will be viewed as simply interleaved chunks of audio and non-audio data with some extensions such as interleaved and non-interleaved stereo streams, differing bit widths, etc). I will be using this primaril...

They like open > and free formats (they also use the LAME encoder). I've thought of doing lossy compression before on instruments, but I'd much rather stick to lossless, at least for now. There are issues to be sorted out
