So u want to make an acapella??? Well here is a guideline how to make it possible without hardware, getting vocals out of the tracks .. just follow it perfectly or it wont sounds like it should..

Well then lets getting started...

--------------------------------------------


1. Get ur mp3 (make sure its atleast 192kps , preferably 256 or more) or WAV (much better obviously)

2. Load it into soundforge and do a 'PAN/EXPAND' process with the settings set to 'mid side' ..
This gives you a WAV with the Left-right material and centre mono material separated..

3. Grab the Centre mono material (which will hopefully have significantly more vocal than instruments/music.. save it as a mono WAV and load into Cool Edit

4. In Cool Edit select a section of instrumental with no vox (bit you want to reduce/remove from the vocal) and get a noise reduction profile (at 24000 FFT size + about 300 snapshots in the profile).. **actually since posting this on GYBO i've found that smaller FFT sizes with a larger no of snapshots can be more effective**

5. then select the whole WAV.. preview the noise reduction.. listen to what it does..

6. In the eq graph line bit.. increase the noise red below 200 hz and less between 300-10000hz .. giving a bit more clarity to the main vocal 'region'

7. Then maybe try some midband compression (300-8000hz) with a very fast attack (with readahead set to about 12ms) and 100ms release.. (i'll have to post a pic of the comp curve to show you how to get good results) to help gate some of the background music left over.

8. Then go to http://www.soundhack.com/ and download the amazing, yet seemingly unheard of,.. spectral plugins (VST) (theres a free trial)

9. go into cubase (or wot ever prog u use) import the 'pella' you've made and use the spectral gate to reduce non fundamental harmonics (see soundhack pdf for more info)...

The trick is to do this 'in the mix' for best results... Using a fast attack and slow release with the spectral gate helps remove transients like snares and cymbals..



This is a method of getting vocals out of tracks I've been using for a while. I've been able to get some pretty good results from it.. most the tracks I've done for MTV have used this method as acapellas weren't available for the tracks i wanted to mix.

I'm looking for like minded, pella-making-people with applemacs! Theres a plugin for SonicWorx called Pandora RT which claims to isolate and remove vocals (not via a Left/Right phase inversion)..I don't have a MAc so i cant try it out.

I think if a few people were to join forces on this we could have a kind of 'pella 'release group'.. where we would combine our efforts to get popular + non-available pellas made pretty quickly.

IF THIS DOESNT HELP TRY ALSO THIS :


Using your favourite VST sequencer and a plugin called Knockout (download).
Mission Statement

This plug was made to help get vox from music in digital
audio. it is not so good at this but can be used 4 other things. it only works as an insert effect and it
expects 44.1 KHz input.
the plug takes two mono inputs in the form of a stereo signal - one hard-panned left and one hard-panned right. the frequencies of the right signal are knocked out of the left signal and the result passed to a mono output. (its a kind of reverse spectral gate with the right input as a sidechain,
maybe if you have a vocal version and instrumental version of the same track, pass them thru Kn0ck0ut at least roughly synced up, the with-vocal version hard-panned left and the instrumental hard-panned right. the instrumental frequencies will be knocked out, im feory leaving just the vocals in the output. but it probably wont so dont expect miracles... experiment with the levels of the two input tracks, try to keep them in sync, use the highest oversampling rate yr machine can deal with, use the other controls to clean the sound. (NB this aint a phase-cancel process, so you dont need perfectly matched audio to get a result - you can try using vocal & instrumental sections of the same track as inputs maybe - but you cant get that perfect phase-cancel style pella you were after either.)

Controls are:
Threshold: level at which quietest frequencies are
removed. turn this all the way up and yr audio will sound like little birds singing.
Lo Cut: hard cut of low frequencies / high pass filter
threshold.
Hi Cut: hard cut of hi frequencies / lo pass filter threshold.
Gain: a simple gain control - no waveshaping, will clip if signal peaks, use yr ears and watch the meters.

Using this method my results have been pretty cool so its definitely worth a try!

If using FL Then load the track into 2 seperate channels then link to fx channel 1 and place the plugin on that.

Then pan the top sample to the left and the bottom to the right and play with the buttons till you get something pretty cool sounding then save as .WAV.

I have found that if u then load it into Cool Edit and play with the FFT Filter the results get better!
