How to cut an audio file

Step 1

To get started, it’s as easy as dragging and dropping your MP3 file into Descript. If your audio includes speaking parts, Descript will automatically transcribe them.

Step 2

Edit the dialog just like you would in a word processor — select the parts you want to cut and hit delete. Or cut-and-paste to move segments around. Remove filler words (”um,” “uh,” etc) in a single click. Or use the blade tool to cut tracks on the timeline.

Step 3

Once you’re ready, hit the share button and select export to publish your audio file online or download to your hard drive.

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.
