Subject: Re: changing a sound signal while listening to it From: Matthias Vormann <Matthias.Vormann@xxxxxxxx> Date: Tue, 10 Aug 2010 08:07:23 +0200 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>This is a multi-part message in MIME format. --------------030806010605060909030509 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit Dear Daniel, try SoundmexPro: http://www.soundmexpro.de/ --> there is a free trial mode with full functinality and it works in Matlab as you were asking for...!
