Gzip will be slow. You might look at some lossless audio compressors. "wavepack" looks like it might work. See here for a good overview with links http://wiki.hydrogenaudio.org/index.php?title=Lossless_comparison#WavPack_.28WV.29
One way to implement this would be as a "filtered" source or sink. Like a file source/sink but the user gets to specify a filter type program that could do something to the data, such as compress or decompress. With luck the operating system would schedule the filter process to run on a different core/CPU and it could go fast --- Dan Halperin <[EMAIL PROTECTED]> wrote: > Has anyone explored inserting a compression algorithm before a > file_sink > or a file_source?
