importing audio

Hi there, im somewhat new to the program. i used it a couple years ago then i had to stop for a while. i want to import some audio to put over my voice for a song remix. please help me if you can.

First order of business should probably be getting the latest Audacity version.

And then after that, you set up for Overdubbing.

There’s simple and perfect overdubbing. Simple overdubbing is where you play the music or backing track to your headphones and sing into the computer. You can’t hear yourself singing.

Perfect overdubbing is when you can hear the music and your voice in correct mix. That one requires a headphone system outside of the computer such as the G-Track microphone.
