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

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
