[music-dsp] Reverb removal

[Alexandros Tsilfidis]

Dear Kenneth,

Dereverberation is still an open and largely complicated research issue. Depending on the application context (and on your needs) there are many methods that you can chose from. However,  from the mathematical point of view blind dereverberation in realistic scenarios is a hard (or impossible) to solve blind deconvolution problem and most methods make assumptions that produce significant processing artifacts. You can download my PhD thesis on dereverberation here:

http://www.wcl.ece.upatras.gr/audiogroup/alexandros/publications/Tsilfidis_PhD.pdf

where you can find a short literature review in p. 31-37. 

Moreover, if interested you can download some of my personal publications and listen to the corresponding audio demos at my personal website:

If you provide me with some more details on the specific application (e.g. how important is the perceptual quality of the final results? do you have any (other) prior knowledge than the recorded sound file? is the computational complexity an issue for you?) probably I would be able to point you out the specific method(s) that (may) suit your needs.

I hope that was helpful!
