Hey everybody... I have a speech signal with too much echo....sounds like the speaker is talking in a tunnel or something....Is it possible to dereverberate this signal? If so, how?

Some methods assume linear system, i.e. that the reverberation was created by a linear system (hopefully a stable one). Then you may such methods as frequency division etc. JAKOB ASHTAR wrote:> Hey everybody... > > I have a speech signal with too much echo....sounds like the speaker > is talking in a tunnel or something....Is it possible to dereverberate this > signal?
