Is there a way to either alter the coefficients of an existing FIR filter or design a new FIR filter, which can be used to convolve with the raw CD data in real time?? I would be interested in trying a Lanczos filter, which works great with image files- I'm very curious to see if such implementation would also work with audio playback.

Responses are appreciated!!

I have never seen Lanczos3 or Lanczos4 used in image processing for anything other than scaling. Please cite an example of where this filter is used for "improving" images.
