muting portions under specified db levels -Sound Forge - PC

Subject:muting portions under specified db levels Posted by: soundforgesound Date:3/7/2007 2:25:50 PM Hi! Does anyone know of a way to have Sound Forge 8 locate sections of a file whose db readings fall under a user-defined maximum level (i.e. noisy 'silent' passages) and to MUTE the contained audio? I'm aware of the auto trim/crop but I'm not looking to delete the space consumed by noisy silence, only to mute it.

This should allow you to create automatic regions with the specific level threshold you're looking for and then go back and easily select the regions to mute the noise sections. Probably not exactly what you want, but that's the only thing I can think of that might get you close to what you're looking for. What it sounds like you are looking for is a "Gate Plugin". Try out the Sony Noise gate plugin included in Sound Forge. Here you will be able to preview the results and make adjustments to the gate for the threshold and attack and release times of the Gate opening and closing, and then when you feel you got it right, you can just select to process it, and Sound Forge will do the muting part for you with the closing of the Gate. Thus, when the audio exceeds a certain threshold level the Gate opens and you hear the audio. when the level goes lower the gate closes and the audio gets muted. So it's the same thing you're asking for but works in the opposite direction as you described.

I had never tried either of the techniques you mentioned and found experimenting with them to be very useful and interesting. The Noise Gate plugin was particularly effective. Thanks.
