1. Re: I want to separate speech from an audio recording
Bob Howes Apr 30, 2012 8:37 AM (in response to cjacs987654)Well, we're all waiting for a chance to try CS6 but, even sight unseen, I'd bet my pension that the answer is "no".
There will be various tools that you can use to enhance your voice and reduce the background (exactly which work best for you will depend on what sort of unwanted noise it is and how severe the problem) but it will be pretty much impossible to work as you want. Some of this will also depend on whether your recording is stereo or mono and how it was recorded. A simple 60 cycle hum can be pretty much eliminated, tape hiss you can do a good job on--but music playing next door is probably there forever.
Your best bet will be to experiment a bit and possibly to post a sample here for advice.

Thanks for your reply.
Yes, will wait for CS6 and have a play. I tried in soundbooth, some success but not perfect. The background noise is wind etc

3. Re: I want to separate speech from an audio recording
SteveG(AudioMasters) Apr 30, 2012 1:41 PM (in response to cjacs987654)The most sucessful way of doing this only works with stereo files, where the voice you want is in one place, and all the interference is elsewhere in the stereo field - there's a tool for getting rid of that, and that's been present for the last several versions. But with mono, you often run into the significant problem of the wanted and unwanted sounds being in the same frequency range, and on the same single track. Remove part of the noise, and you unavoidably also remove part of the signal. Usually when you do this, the side effects are worse than the interference on the original signal. With wind, you stand some degree of chance of removing some of the effects - the low frequency rumble it creates is outside the speech band, and can easily be attenuated to quite a degree using EQ. But the rest of it is a lot harder - using downwards expansion sometimes helps a little if the wind noise is relatively quiet, but here you really are in the realms of potentially making it worse rather than better.
You might find that using adaptive noise reduction helps a little - but without actually trying it, it's very hard to tell.

Thanks for your reply andf useful advice.
I now have CS6, so will give it another go,
Thanks

It will apply to CS6 equally.
