Adaptive Noise Filtering -software solutions.

[admin]

Based on an idea I put on QRZ a while ago:
ANF is so much more effective than simple parametric audio filters to lift intelligible audio out of noise.

Hardware solutions are expensive -CLRdsp, BHI solutions, and while they learn the background noise and subtract it, there is not a lot that can be adjusted to improve their performance. My NR on my IC-7610 is adjustable only in degree; there doesn't appear to be be any learning or adaptive ability.

Open Source solutions suggested online include :
