i've got a question - can i make a program for mixing (for djs) with bass? i need to speed up the mp3's (i need to have 2 mp3's and every one has to have its own speed which the user can change); every mp3 has to be played by another sound card. do you know some good functions or procedures which can help by this? or maybe has anybody already tried to make such a program? please write your suggestions. thanx
