Anybody know how of a software application or procedure to invert the transfer function of a loudspeaker (i.e a horn or waveguide) to eliminate or minimise transient smear? I'm interested in what David Gunness describes in his paper: Improving Loudspeaker Transient Response with Digital Signal Processing. The paper is here: Improving-loudspeaker-transient-response-with-dsp-2005.pdf at Share Send
Idealy a FIR filter can be created and run on a SHARC processor such as the one available from MiniDSP (miniSHARC Kit | MiniDSP)

Ultimate Equalizer is interesting but alas it seems be aimed at those looking to address room / loudspeaker issues. Using UE seems to lean towards running filters with a enormous number of taps on a PC. Where as I'm interested in addressing loudspeaker design issues (such as in horns, sans room) with fewer taps on stand alone SHARC processors.
Another challenge here is how to isolate the problem from the 'total' sound so it can be filtered out. Deconvolution?
