Re: changing a sound signal while listening to it

[Matthias Vormann <Matthias.Vormann@xxxxxxxxxxxxxxxxxxxxxxxx>]

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...!

I have done similar things with changing signals online and listening to
it at the same time (with a very short delay of course) - it worked fine...

Best regards,
Matthias
