make all samples the same volume

any of u kats know how to make all the same samples in ur project the same volume.

i chopped up diff parts of an acapella on differnt days, thus that led to different levels in each sample, how do i go about getting everything the same volume.

should i just normalize all samples within sound forge?

Normalizing is a good way to go, but it only goes so far. If there are dynamic changes in the overall acapella, the noise level will be much more prevailent in the samples that are quieter. Normalizing will bring everything up in a sample, and that means abient noise as well. The result is that, instead of sounding even, the listener just hears that you turned the quiet ones up. If the original performance isn't too dynamic, normalizing is a good idea. But if not, here's what I do when I have the same situation: Run a compressor/Limiter plugin or process on the overall acapella before you cut it. A limiter is the best for the job, if you have it. Likewise, if you have outboard gear, record the acapella through the outboard Limiter into Soundforge first, then cut and normailze.
You want to limit it enough so everything comes up around the loudest points, but not som much that the noise level is boosted to an apparent level. Something like a 4:1 ratio, with a threshold low enough to cut injust touch lowest vocals in the accapella. If that squashes the louder parts too much, abviously lower the ratio a bit. Then, when you are done processing, you can normalize or mix the volumes just a bit to even them out some more. Then turn the cuts into individual files, save to disk, and put them in your sampler. Or, leave it uncut, and record the overall back into the ampler and cut there. No need to cut twice, right? Again, don't go crazy with the comp/limiter, but just enough to whip them into shape. Post again and let me know how this works for you.

i dont know if this is gonna help you, but it might somebody else so i'll post anyway. i am a post production sound designer, meaning that i mix and design tv shows and commercials. one of the first things we do once we get a project in is to hit up the dialog and voiceover sections. generally the first move i make is to insert a limiter and automate the threshold of it. you have to have a limiter with automatic gain make up for this trick to work. so you go in and when the dialog is low, you lower the threshold thereby increasing overall level. if it is too loud just raise the threshold. i think this move works better than just turning the volume fader up and down. but you end up with an automation line that is zigzag but overall level is generally equal. i do this in pro tools with the maxim limiter, but you should be able to do it in just about workstation that has automation features and a limiter with automatic gain makeup.
