How to split audio at silent parts in Audacity?
If you want to split audio into audible parts only, then you have an option to remove silent parts and split an audio track into smaller chunks. It’s very useful when recording your lines for a voice-over project.
Here’s how you can remove silent parts and split audio in Audacity:
- After recording go into Multi-view mode (Audio Track>Multi-view). Multi-view will show you where the silent parts are which you can’t see if looking into waveform only.
- Select your whole recording and apply noise gate effect (Effect>Noise gate). Noise gate is not available by default, you’ll have to install it as a plug-in, you can read how to do that here. Alternatively, you can apply Amplify effect onto parts that you want to make silent, but that’s a longer route.
- In noise gate apply a maximum (-100dB) Level reduction and click OK. Now the background noise will be deleted and you’ll have silent parts in your audio.
- Go to Edit>Clip Boundaries>Detach at Silences and you’re done.
