Like many other features, Audacity also has the feature which allows you to create multiple soundtracks overdubbing. Basically, this feature allows you to record one track as you normally would and then play it and add a second track against it which may include drums, guitar, violin, or voice. You can also repeat the second track as needed.
For this feature, Headphones are essential as you will be able to hear a mix of your live recording and the previous tracks simultaneously in your headphones. So, headphones are must for overdubbing.
You will need hardware that will allow:
- The sound to be recorded
- Listen the live sound
- Listen to the previously recorded tracks along with the live sound
A USB Audio Adapter or A USB Headset will work just fine!
You should make the first recording without any overdubbing or anything. Make the first recording and listen to the playback while you record to hear your voice or instrument along with the plack.
This will be what you will hear during the overdubbing session, your original record along with a combination of the new tracks that you are recording.
Set the recording latency
Recording Latency refers to the delay time between the audio enters the computers and Audacity records it. You should adjust the recording frequency accordingly.
