    Sound Studio can filter out certain frequencies.

    You can't do it properly unless it's a MIDI file. You're never going to be able to maintain the quality of the background while removing the voice. Just buy karaoke tracks.

    You can't do it properly unless you have separate audio and vocal tracks. There are complex programs that can try to do it, but the result tends to sound very strange since vocal and instrument use a lot of the same frequencies.

    Right, the vocal frequencies are embedded throughout much of the audio file. Once that's done, you can't remove it completely without removing tons of the rest of the audio. Think of a .wav file or .mp3 as a concrete form. You can paint it a different color (add reverb or some other effect) but you can't change its basic structure.

    You need someone to recreate the track for you from scratch or, as another poster mentioned, find a midi file and delete the vocal melody in the midi file. good luck!

    There are some other ways with phase cancellation but this only works if the vocals are only in the center. You can flip the phase of the L or R channel, and sum to mono, canceling out anything that is only in the center channel.

    This will also usually get rid of kick drum, snare, bass, and anything else in the center, so don't expect the song to sound fine afterwards, but it is a more effective way than trying to use EQ to filter out vocals.

    EVERY instrument has information in the frequency range of vocals, so be careful with EQ. You will never get rid of all the vocals, and just end up ruining every other instrument ;)

    Good luck!
