Removing bad echo/reverb

Archived from groups: rec.audio.pro,rec.audio.tech (More info?)

Here is a question for you techie's:


I recorded a friend of mine giving a speech. It is in a large
building made of cement, brick (this is a very old bldg in
China) and the reverb/echo of his voice is really bad.

I took the audio and was able to run it thru a DX plugin to
remove hiss and the result sounds pretty good as far as hiss
goes. Now I would like to minimize the echo/reverb.

A friend of mine suggested I take a vocal remover, remove
the vocals, and then invert the signal. Take the inverted
signal and merge it (or mix down) with the original.

Any suggestions? If the vocal remover is the right way to
go, any suggestions on which one to use?

BTW, I'm using Cool Edit Pro 2.0.

Thanks,

In this case, I couldn't. It is the audio part of a video and
it was in the best place for video (no mic cable for the camcorder).
The building, being made of 90% concrete really bounces the sound.

I'll give it a shot.

I figured as much. I've run it thru noise reducers and manually
removed some frequencies and it is much better.

Thanks for your ideas.

Pardon my ignorance, but if it's your friend, perhaps he could lipsync the speech
again in front of a real mic?
