Subject: Re: Matlab code for deconvolution? From: ita katz <itakatz@xxxxxxxx> Date: Wed, 9 Jun 2010 22:41:52 +0300 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>--0016e646058a093c1404889e19ce Content-Type: text/plain; charset=ISO-8859-1 Dear Ursula, In Matlab's Image Processing Toolbox there is a deblurring function called deconvlucy, based on Lucy-Richardson method (used as well to deblur Hubble's space telescope images). Of course you are talking about audio and not an image (1D instead of 2D), but the underlying signal processing principles are the same, so I believe you'll be able to use it, possibly with some tweaking of the algorithm.
