Hi

I have been trying to remove all background noise from a movie sample. I have applied a Low Eq cut to the bottom end of my sample but i havent been able to remove it. Any ideas really appreciated. Or is it impossible to do without effecting the vocal sample?

Thanks

Normally when I work with vocals I often cut alot of the bottom, either with eq or filter, depending on what sound im going for, then it's just about boosting alot of freqs just to find what works best with the rest of the track.

a little tip - when working with vocals like that (spoken,movie samples etc) you can forget everything you know about treating vocals. everything that matters is making sure it's clear enough to understand what's being said (or not for that matter techno!!) and hiding what you can't remove of dust noise in the perc freq area.

you could also try running the signal to two different fx channels, and use the transient designer of you choice to increase the attack and lower the sustain on one of them and cutting everything below like 4-5000 hz. putting a nice delay and some reverb works well on this channel. then do some eq work on the other channel, bus them together and slap on some light compression. often helps turning the delay wet level down at this point also as the compression can often pump up the delays.

What's the background noise? Is it music? What instruments used? If it's too much in mid frequencies chances are it's not going to be easy to do it.

Another thing that could be possible is if the vocal is mono and rest is side info or the other way around. I would check for that.

There are some de-noisers, de-hummers, etc. out there. Waves, Izotope, etc. make some pretty expensive ones, but I'm sure that there are some freebie equivalents (check the KVR plugin database).

Some of them work on a principle (phase cancellation) that you can try yourself. If the background noise is relatively static, see if you can isolate a small portion of it, put it on a separate track, loop/extend it for the same duration of the original clip, and reverse the phase of the noise track. Buss the two tracks together and the noise will hopefully be reduced.

A similar approach is to duplicate the track, reverse the phase of the second track and use an EQ to isolate the background noise frequencies (i.e., so that mostly just the noise is heard on the duplicate track) if you can, then buss them together. If it's a relatively narrow range of noise frequencies that can be isolated easily with EQ, then this approach will probably give the best results.

try converting the sample to mono and paning to clean up the sample and try running it through diffrent vst fx but dont effect it to shit just try and clean up the sample instead.

The frequencies in a "voice band" are in the range 300 - 3400 Hz. So you can probably remove anything outside of that range without affecting the vocal sound too badly.

this one should help you

Some very informative posts there (-; Some i think I wil need to re-read again! I do a low cut normally and boost the freq where the vocals seem to be peaking but the background noise in general whatever it may be I cant seem to shift! So somewhere along the line im doing something wrong if vocals tend to sit in a certain spectrum i am missing something! I shall look into some more!

Thanks a million for the replies,

Depends on the noise but I would try noise gate...

i writed a song.

In my experience a good denoiser can work miracles if you use it right.

Also if you can get hold of the 5.1 mix for the movie in question you might find a center channel that holds the voices isolated from the rest of the mix.

yeah nice, I checked out izotope which seems really good. Thanks heaps for the replies there is more then enough info here now for me to go on,

cheers
