How to cut and edit MP3 files

Step 1

Upload your MP3 audio file

Upload your MP3 files to a new Descript project or press the Record button to start recording new audio. You can also add sound effects and music by clicking the Media icon to access our built-in stock media library. The fastest way to trim, cut, and rearrange is in the auto-generated transcript that’s synced with your audio.

Step 2

Edit using the transcript or timeline

Delete, cut, and paste like you would in a text doc. To adjust EQ and make other audio edits, click the audio layer in your timeline and use the properties panel on the right under Audio Effects. There are also AI effects and actions you can apply in one click, like filler word removal to cut "um" or "you know" in dialogue, and Studio Sound to eliminate background noise from audio.

Step 3

Export your MP3

Once you’re satisfied with your audio file, all that’s left is for you to export or publish it. Click Publish to open a dropdown menu where you can choose your preferred audio format to export, or create a web link you can share or embed anywhere.

Cut MP3s with Descript’s professional audio editing software

Sound like a pro

Whether your audio recordings come from a fancy mic or something you mumbled into your phone (iPhone or Android), use Studio Sound to reduce noise and enhance your voice. Descript’s filters let you normalize, equalize, or get dirty with a flanger and other effects.

Transcribe like a fiend

After Descript transcribes your recordings, you can edit MP3 files like they were text. Don’t like what you said? Descript’s AI lets you change it just by typing — using our Overdub voice synthesizer.

Transitions

Cover your cuts using one of the fundamental editing tools, transitions. Use a simple crossfade, or have a popular song fade into the foreground to captivate your audience.

Frequently Asked Questions

Can I export an MP3 as a video?

If you want to put your MP3 online as a YouTube video, don’t forget that Descript is also a video editor. It’s as easy as dragging a still onto you timeline and exporting it as an MP4 instead of an MP3. You can also use Descript’s video effects, like waveform visualizations and Fancy Captions, to make your audio come alive.

Can Descript edit other audio formats?

You can use Descript as an audio cutter for almost all file formats, like FLAC, WMA, AAC, and WAV, though only up to two channels. Pretty much anything goes but OGG. You can also work with audio from video files like WMV, MOV, and MP4. Want something other than an MP3? You can export as an AAC or a lossless WAV if you don’t mind the bigger file size.

Can I use Descript’s MP3 editor for free?

You can cut MP3s and upload unlimited audio files online with Descript’s free version and get your first three hours of transcription free. Need more transcription? Upgrade to the $12/month Creator package or $24/month Pro package for 10 or 30 hours, respectively. Contact us, and we’ll negotiate pricing with you for the Enterprise package, including training, onboarding, and a dedicated account representative.
