soundforge help...

alright...

well i've always heard that you can like invert a sample and get it to cancel out another part in a song leaving the part that you want, but i've been trying to do it the last few days and haven't had much success. so is it possible to do and if it is can someone go over it.

Well, it's quite simple. Use the sample you want to cancel out of the song. Now invert it and layer it exactly over the existing part of the song, with the same sample that is not yet inverted. You shouldn't hear that sound anymore now, in a perfect situation that is. It always depends on how much other sounds there are playing in the song, whether this will work. You can only perfectly cancel out a sample if there is nothing else you hear.

Hope this makes sense...

yeah thats what i've been trying to do...i don't know maybe i just don't got the skillz hehehe. maybe there is other stuff going on. i just thought that say your regualr trance song that starts out with a beat and then gradually introduces new stuff would be easy to obtain samples from in this fashion...maybe i should try it more and zoom all the way in hehehe...

yeah, you definitely have to work with great detail and accuracy. But in the end you hardly ever succeed, because you often got phasing problems, or weird sounds.

Well good luck anywayz!

Sure is hard to cancel out just one sample of a song. Inverting (the wav's phase) works best on an entire song, i.e. to cancel out the mono parts.

Dont try it with mp3's tho. Pure wav's are the way to go.
