Does anyone know of a way to remove room echo or reverb from a speech recording? Unfortunately, I have a tape of a stage performance with good video and awful sound - the main problem being room reverb. Clearly, the mics were too far from the performers. I've tried expansion which gives a slight improvement but introduces an odd sort of distortion, compression which makes it worse and noise clipping (gating) which has proved ineffective. All of these effects are from Premiere and/or Soundbooth.
Are there any software applications or plug-ins that specifically address this problem?
