dass das mit 2 runtergeladenen mp3´s net gehen wird is klar.. wenn dann natürlich wie gesagt höchstens mit ner maxi cd mit 2 tracks, die dann genau gleich auf die platte gerippt werden.. 2 verschiedene encoder, und es klappt schon nicht mehr.
hier nochmal was der typ im forum meint:
There are things that must be correct for this to work..
1) The audio must line up EXACTLY. If you have a file ripped from a turntable, it will not be exactly in time with one ripped from a CD or even another turntable.
2) The quality/compression must be the same. If you have two files and one was compressed slightly you will not get good results. Also if you have two MP3 files created at different bitrate or by different encoders, they will not give good result.
So unless your two sources are equitable, you may not get good enough results. There is nothing you can do about this.
sometimes the instrumental gets mastered differently than the song with vocals. That would make it different enough to not work very well. The #1 technique for getting an acapella, is to get THE acapella.
