What is the best software for recording your voice?

what is the best computer software where i can load my karaoke songs on and add my voice onto the tracks from my own computer?

I can tell you that if you get yourself a decent computer mic, Audacity is completely free and will do all that for you. The best freeware software I have ever found.

Audacity

Heres the site where you can dl it:

Sony Garage Band, and get a good mic.

Just grab audacity, which is free software and perfectly suited to your needs. I use it to make audiobooks.

ps, my answer is slightly better than Bill's because i rock harder.

garage band is one of the best and cheap

Cool Edit Pro
u can change the volume, echo, How fast u want it to go etc.

its all about the mic not the program. I would def say get a condenser mic (MXL's are really good) its what we use in the studio to get a good sounding vocal tone
