Thanks for asking us. I moved this to the Vogone Help Forum where it belongs.
You want to perform what is called Vocal Reduction/Removal, which our Vogone product is designed to do.
First, using MP3 compressed songs and trying to remove the vocals is not the ideal solution. If you can get the actual CD and import the track without MP3 compression, you can do a much better vocal removal/reduction job on the file. The mp3 compression damages the file in ways that prevent or reduce how much of the vocal you can remove. Having the original will allow you to be happier with the results.
Second, Vogone only processes .WAV files, which is the format imported from CD Tracks using most software, including our Microstudio software.
With Microstudio 4.000, you can write .mp3 audio files to an Audio CD disc. The audio tracks can then be imported back into Microstudio as .wav files. Thus, you can convert mp3 to wav now with Microstudio 4.000. We are working on version 4.002, which adds a format converter where you could convert your mp3 files directly to wav files, then process with Vogone.
We have a demo of Vogone you could use if you can convert your mp3 to a wav. Vogone will NOT do a perfect job on all songs, but it will do a better job than any competing products based on what users of both have told us.
There are about 25% of songs that no vocal reducer will do anything with. Please read our
Expectations document on Vocal Reduction. It will help you understand what is feasible, to see if that is what you want to do.
Again, thanks for asking us. I hope this helps you.
