Record from 2 source

Hello guys, my name’s Giacomo, i’ve a little doubt about the possibility of record from more then one source like mic with Audacity, my problem is that i need to record my voice syncronized with the an audio/karaoke from youtube, for have one Audacity project where there are 2 twotrack.
One track with my voice and the other track with the audio that i listen from the speaker.
Thanl a lot for the future answer

Best to do this all in Audacity rather than playing from your web browser.

The first thing to do is to set up “latency correction”. See:

Then the process is quite simple:

  1. Download (or record) the backing track (there are plug-ins available for Firefox for downloading from YouTube).
  2. Import the file into Audacity.
  3. Record your voice.
