getting started on dereverberation

Started by dudelsound 2 years ago3 replieslatest reply 1 year ago87 views

Hi everyone

I am trying to dig into the topic of dereverberating an audio signal - e.g. a microphone signal picking up direct sound and room reflections of a speaker signal - without any (detailed) advance knowledge of the signals.

I am free to use multiple microphones if that helps.

I guess the challange is to remove self-correlation within a reverberated audio signal without removing the natural self-correlation present in the unknown dry source signal...

Can anyone provide me with good articles or books or even helpful google keywords to look up just to get started on the matter.

Check Patrick Naylor, his research group, and the dereverberation book.
Another researcher in the field: Emanuël Habets.

Good luck!

It's quite dated, but check out Duane Cooper's work at the University of Illinois on "Transaural Processing": https://www.researchgate.net/scientific-contributi...
