Subject: [Audacity-devel] Possible improved click removal


I'm a developer [1].  I recently acquired a copy of Audacity and wonder if its click removal could be improved.  It appears that most of the time the program draws a straight line across the lost region, which is waaaay better than the original click, but I think could be improved.  It happens that I've written a program in C++ that does phased extraction on the harmonic content of a signal, leaving inharmonic "mud".  That could be done on each side of a click and, I think, the results projected across the gap, preserving the phase of harmonic signals for a smooth connection at each end.  I believe this should be possible even for high frequency components, reconstructing many cycles within the lost region.  The remaining mud, or hiss, could be propagated across the gap by any of several techniques, and preservation of phase is not important with hiss, as long as care is taken at the connection points.

Does this seem like an interesting enhancement?
