Recording desktop audio

Audacity can record computer audio (including sound from YouTube, Spotify and more).

1. Select the loopback device

Click on Audio Setup and select Windows WASAPI as the Host.

Select the output you want to use (the device you're using to listen) as the input. It will be marked with a (loopback) after it's name.

When using the (default) MME device, you may find a virtual microphone called Stereo Mix, What you hear or similar in it. This also will record your desktop audio.

Note: MacOS does not have built-in desktop audio recording capabilities. You'll need to download Soundflower to record desktop audio.

Soundflower

Caution: Soundflower is not compatible with Apple Silicon-based machines ("M1", "M2", ...)

Download Soundflower from https://github.com/mattingalls/Soundflower/releases/ and follow the instructions provided there to install it.
Open the Audio MIDI Setup app (found in /Applications/Utilities).
Press the + button in the bottom left corner and select "Create Multi-Output Device".
In the panel that appears to the right, select Built-in Output and Soundflower (2ch).
Press the gear button in the bottom left and select "use this device for sound output". Note: If you don't set an option, you won't hear anything after completing the following steps.
Start Audacity
Click the Audio Setup button and set Soundflower (2ch) as the recording device.

2. Check if everything is set up correctly

Recording the desktop audio will record all desktop audio, including notification-pings, games, and Audacity itself (for example, other tracks in the timeline if you're using overdub). So unless you specifically want these noises, make sure to turn them off.

DON'T use software playthrough when recording desktop audio. Make sure it's off in the menu: Transport > Transport Options > Software playthrough (on/off) - The ✔️checkmark next to it must be turned off. You can turn off overdub here as well.

3. Record

Hit play to ensure audio is playing and then the record button to record your desktop audio.

Ensure audio is playing first when recording desktop audio as although WASAPI can record a silent audio stream it can’t record when there’s no audio stream.
