So I'm trying to do that trick where you invert the instrumental to get the a cappella. I'm using these tracks:

because I've been trying to get a vocal track of this since forever. I even contacted DJ Chris "The Greek" who did a remix of it, however he since threw it out. But anyway, I've been trying to do it in Pro Tools, and it's just not working. First of all it's hard to line it up in PT since you don't actually see the waveform when you move the audio objects (anyone who uses Logic knows what I mean), but I think I'm doing something wrong. I import them both, invert the instrumental, and it drops out the bass, but that's it...
Are the MP3s too crappy quality or what? Is there any way to get an a cappella from this? Maybe if I bought the CD and imported it lossless? |

You hit the nail on the head, MP3s files have data removed during the encoding (basically bits it feels are not important and cannot be easily heard)
These bits are however gonna be needed to invert the phase.
I would strongly recommend using only original CDs to have any chance of good results. |

Having perfect copies ripped directly from a CD may not always work though...
I recently encountered a track where the instrumental version was timestretched to be milliseconds longer than the full vocal version which was enough to scupper the phase inversion process.
It would seem some artists/labels don't want DIYers to get their filthy mitts on their vocals! |

| I've used pro tools a couple times in the past but don't own it so I can't go step by step through it. i use sonar, and this is how I do it. I make a track, I don't do copy and paste and try to match. I simply hit clone track and the two match perfectly and then hit the phase reverse. no audio changes and that's why I have a hard time to believe the same mp3 file is hard to phase. but yeah, working with audio cds will leave better results then mp3s. if you do use mp3's, make them lo-fi. |
