Hi,
I want to remove vocals from mp3 sound tracks. I searched google, and tried few softwares but none of them are convincing. I am planning to read the mp3 file, get a waveform and remove the waveform that is above a specified limit.
do you have any suggestions on how to proceed.
-- Update
I just want code that can read mp3 file format. Are there any softwares??
Above a specified limit? sounds like a high pass filter...You could use phase cancellation if you had the acapella track along with the original. Otherwise, unless its an old 60s-era track that has vocals directly in the middle and everything else hard panned, i don't think there's a super clean way of removing vocals.
This isn't so much an "algorithm" as a "trick" but it could be automated in code. It works mostly for stereo tracks with where the vocals are centered. If the vocals are centered, they manifest equally in both tracks. If you invert one of the tracks and then merge them back together, the wave forms of the center vocals cancel out and are virtually removed. You can do this manually with most good audio editors like audacity. It doesn't give you perfect results and the rest of the audio suffers a bit too but it makes for great karaoke tracks :)
