Asking for tips to deal with audio adjustments (remove background voice + part of main voice)
by Carlos Silva on Jul 12, 2012 at 9:02:09 pm
Hi,
I have two issues related with same audio event.
a) In the background there are people talking and it is undesirable. Is it possible to apply any filter to remove this background voice?
b) In a very exact part of the audio there is a short undesirable sentence of the main voice I would like to remove. I tried to lower the volume through a volume envelope, but it affects the general sound of the audio. So, would it be any workaround to deal with?

a)There is not really a way to remove that background audio without affecting the main dialog. Adobe Audition/Soundbooth has a good filter that can reduce steady background hiss/humm/noise and that may reduce it somewhat. If possible the right way to fix this is re-record the audio if possible
b)When I have to edit audio that has some background sounds/ambient noise I usually grab a section of audio where there is no dialog and use that as a background replacement so when the main dialog drops out there is a some background noise still there and it doesn't sound so odd. Fadeing it in and out helps it seem natural too.

Chris is right. Replace that portion with another portion of audio that does not have the undesirable part. Another trick I sometimes use is to mask it with another sound effect. For instance if someone says a few words you don't want distinguished in a room with people eating lunch for instance, you might put in a sound effect of a few dishes clinking on another track.
A cut away shot of something else helps a bit too. So if you want to further mask the sound, you might put a cut away shot in of a the dinner plates with someone picking up a fork and then add the additional sound over that.

Thanks everybody for valuable tips!!!
About the comment "Adobe Audition/Soundbooth has a good filter that can reduce steady background hiss/humm/noise", does anyone know if SoundForge provide similar feature?

soundforge can't. izotope rx2 has spectrum editing. it can do amazing things, but like all tools you would need to spend time learning it (or pay someone like me who runs a commercial audio/video studio) to do it.all the suggestions from the guys above are good. but sometimes you might have a line of dialogue that you must keep, but a noise (e.g. a bump)happned at the same time. rx2 allows you to go in and remove the bump while retaining desired audio. here is a link to a little job i did for someone, removing mobile phone interference from a wedding video soundtrack, using rx2:
