An introduction of Audacity's loop-based music making capabilities |
You can find loops all around the internet, including Muse Hub.
You also can manually convert a section of a song to a loop.

When importing a loop to the project, Audacity will automatically attempt to match the tempo. If it's unable to, you can instead adjust the tempo yourself by holding Alt (macOS: Option)and dragging the edge of a clip to stretch it to fit.
{% content-ref url="../../audio-editing/speeding-up-and-slowing-down-audio.md" %} speeding-up-and-slowing-down-audio.md {% endcontent-ref %}
Additionally, if the loop is in a different key to your project, you can also select a clip, and press Alt+↓↑ to adjust the pitch by semitones.
{% content-ref url="../../audio-editing/changing-pitch.md" %} changing-pitch.md {% endcontent-ref %}
Audacity does not feature a looping feature as known from traditional DAWs at this point. Instead, you can repeat via copy-pasting the loop, or using the Effects -> Special -> Repeat effect.
