David,
Each person has a different expectation of vocal reduction/elimination. Vogone 2 is the most advanced product on the market that we, and our users, are aware of.
I don't believe Vogone is the problem. You should also read our
Vogone testimonials to see what results others are getting.
If you are getting no results at all, there is something wrong.
1. What is the processor speed you are running (350MHz, 700MHz, 1.6GHz, etc.)?
2. What type of speakers do you have connected to your computer?
3. What audio card are you using in your computer?
All these can affect how Vogone performs. If your audio card and speakers are poor quality, you won't be able to hear the frequencies to adjust.
I am not aware of a song where the controls won't have any effect at all. Since you haven't given us anything to go on in the way of facts, we can't help diagnose your problem yet. If you want our help, tell us what you are hearing and doing.
