Thanks to the team who created this great software.

I would appreciate if someone could advise on how to use the vocal remover function.
The following are the steps that I have taken. I wonder if I have missed any step?
File -> Open ->mp3 song
Edit -> Select all
Process -> vocal remover

Many thanks in advance.

don't forget, that a vocal remover only works, when the vox are centered in the stereo panorama! unfortunately, all other instruments in the center will be deleted too, for example bass guitars (are in the stereo center most of the time) and so on.......
a vocal remover never brings up good results....

Yes you are right Toxonic.

To complete your post, I precise that the stereo panning of mp3 is altered due to compression, and the vocal remover could have strange behavior.

We experiment this with wav extracted from CD, and it associated mp3: the result seem different.

Thanks to both for your kind responses.

I like to remove the vocal part of some songs (some in wma format, some in mp3 and some in wav) ie to retain only the music . It's OK if the result is not very good.
Do i need to download any other files in order for vocal remover to work?

Would appreciate if you could advise further on how to use WAVOSAUR to remove the vocal part.
Thank you.

I think VST plug could do these sorts of treatment. Try to ask Rex about this, I think I could answer you. He has very good knowledge of existing VST .

Vocal extraction is very complex: the wavosaur algo is very simple, it just eliminates centered material on stereo files.

We are working hard on the Wavosaur engine, the editor stability etc. More complex effects should appear soon, but have low priority for the moment.

Hi Jasmine,
There are some VST plugins effects intended to achieve this difficult task.
I was talking about VST from Elevayta (extra boy) in this topic :

http://www.wavosaur.com/forum/splitting-voices-and-background-music-t152.html

You can't expect a perfect result but it can help!

If you have an acapella version of the song, you can also try to "substract" the acapella from the normal song and then have the instrumental part. I tried with the Kn0ck0ut VST plugins (spectral processing) http://www.freewebs.com/st3pan0va/ : you must have the acapella on one channel (LEFT) and the normal song on the other channel (RIGHT)

Tell me if it helps!

Rex, thank you so much for your kind assistance.
I downloaded Kn0ck0ut and experimented it using different settings for the controls but was still unable to remove the singer's voice from the song Sad

I could not try the extra Boy vocal removal VST plug-in because I do not have a credit card to pay for the bandwidth fee imposed.
