Frequently Asked Questions

Can I add music, sound effects, or ambiance to my uploaded files?

After you’re done removing all the unwanted parts of your podcast or whatever, you probably want to add music or other ambient effects, like your ringtone (which is just a recorded version of you screaming “ring-ring!”). To add music, a sound effect, or any audio file, you can simply right-click, and drag the file into your script where you want it to play. For more information on fine-tuning your audio, watch the tutorials in our Help Center.

How do I work with simultaneous tracks of voice audio (multi-track)?

Use a Sequence to group tracks into a single Clip with a combined transcript. Sequences are created automatically when you create a multitrack recording, or if you import multiple tracks, such as music files, that were recorded outside of Descript.

What file format types are supported?

Whether you want to extract audio from a file from your iPhone, Mac, or a non-Apple product, Descript supports most audio formats (except WAV files that are more than 2 channels and OGG files).

Does Descript include all the features of a fully powered audio editor?

All the ones you really need. While Descript started out as a glorified transcription tool, it has evolved to become a fully powered audio editor. It doesn’t have all the features you’ll find in legacy DAWs — but the ones it’s missing aren’t really necessary for 99% of creators.

Can I trim audio on a video file?

Not only is Descript amazing for audio files, but with the video editor functionality you can also do your video editing right there in the transcript.
