Awesome as always, Tom!Pipe-support is sweeeet! It actually makes a significant performance improvement when using foobar2000 on a quad-core machine, since the stress of multi-threaded conversion on the hard drive is much less. Thanks a lot for your efforts!
I've just released shntool 3.0.6, which adds support for TAK encoding.
Surprisingly even encoding got faster, although i haven't performed any optimizations! Possibly the modification of the window function of the predictor, which is also responsible for the tiny compression improvements, affects the choice of the predictor count: Less predictors = more speed.
