Llorean:
Yeah, and when Preglow offers to help optimize, you should accept. ;-)

Mr. Brownstone:
Great work Marsdaddy! 8)

It's not that kind of inaccuracy, which makes me think it's a simple bug -- I encoded a simple sine wave to wma which I then decoded to wav and compared to the original sine wave - it's smooth enough but every so often the sample becomes inverted. I will however probably switch to using 64 bit before submitting.

I appreciate the comment about optimisation and once I shake out these basic decoding bugs I will submit -- functionality before performance!  ;)

Thank you all for your kind comments and interest - it's appreciated. Nice to be a small part of something good.

It sound to me like the sample value could be overflowing. I believe Musepack originally had a similar bug, which preglow fixed.

if this is integrated by the time 3.1 is released, it will make the first official build on iPod even better
