I have a digital recorder that I record a lot of conferences, but I get an echo on them how can I remove the echo with Sound forge 8, with noise reduction? Thanks Bill

It may or may not help depending on the kins of echo and the frequency of the echo.

play with EQ, reduce the mids, use heavy compression and that will reduce echo - it may also affect the dynamics of the sound recordings to an unacceptable level. Unfortunately there is no easy fix.

Leedsquietman is right. There's no magic solution to the problem (though I've often thought that noise cancellation technology of headphones might be adapted for this sort of thing).

In any case, like a LOT of questions posted here, the solution lies not in SF, but rather in the source recording. If you're recording conferences, change your microphone to something very cardiod, or even a small lavalier mic that the speaker can wear (there are some excellent wireless options out there).

Using a gate may help some of the reverb problems in the room...gently cutting off the reverb when it falls below a certain level.

Then EQ, and compression may help too.

If the room really is that echoey, then you simply MUST get closer to the speaker. Asking for access to podium shouldn't be an issue, and most people forget they're wearing a mic when you pit in on them anyway. And, ultimately, the results will be MUCH higher than just micing an amplification system from a distance.

good advice, gating with regards to everything else should help a little and some good advice re mic placement.

Also lo pass filters might help, there won't be much spoken word in the 6 Khz and above range but here could be echo there, so cut freqs above 6 Khz might help also.

Whatever, you will probably be able to reduce the echo but by how much is the million dollar question...
