Noise reduction sample

Related to this thread:

This is a sample of audio before and after processing with a noise reduction algorithm that I've written. The sample comes from an old (early 70's I think) pre-recorded cassette tape, without Dolby encoding, so the tape hiss is audible throughout. I hope you'll agree that the noise is lower in the processed sample (_nr suffix), but I'd be interested to know how it compares with commercial NR algorithms in terms of sound quality. I've included a sample of the bare tape hiss if anyone wants to try!

Comments welcome...
