How to Edit Podcast Episodes by Editing Text with Descript AI

Podcast editing traditionally requires hours of scrubbing through timelines, listening repeatedly, and manually cutting segments. Descript transforms this process — you edit your podcast by editing a transcript, like working in a word processor. Here’s how to produce a polished podcast episode using Descript’s text-based editing.

Step 1: Import Your Raw Recording

Open Descript and create a new project. Drag and drop your raw audio or video recording file into the project. Descript supports MP3, WAV, MP4, M4A, and most common media formats. Once imported, Descript automatically begins AI transcription — this typically takes 2-5 minutes for a 60-minute recording.

Step 2: Review the AI Transcript

Once transcription completes, you’ll see a full text document on the left side of the screen, with the corresponding media timeline on the right. Read through the transcript to identify sections you want to cut — off-topic tangents, redundant explanations, awkward pauses, or factual errors.

Step 3: Cut Unwanted Content by Deleting Text

To remove a segment, simply highlight the unwanted text in the transcript and press Delete. The corresponding audio/video segment is automatically removed from the timeline — no manual scrubbing, no precise timestamp hunting. Delete multiple scattered phrases across the episode and Descript seamlessly stitches the remaining segments together.

Step 4: Remove Filler Words Automatically

Click the “Remove Fillers” button in the toolbar. Descript’s AI scans your entire transcript and highlights all filler words — “um,” “uh,” “like,” “you know,” “sort of.” Confirm the removal and Descript deletes every instance simultaneously. This single step typically saves 5-10 minutes per episode and dramatically improves listenability.

Step 5: Use Overdub to Fix Mistakes

If a speaker said something incorrect, instead of cutting the segment, use Overdub. Highlight the incorrect text, type the correct version, and Descript generates the corrected audio using the speaker’s cloned voice. First-time users need to record a 10-minute voice sample for cloning; after that, Overdub works instantly for any correction.

Step 6: Add Intro/Outro and Music

Import your podcast intro music and outro files as additional tracks in Descript. Drag them to the beginning and end of your timeline. Adjust volume levels using Descript’s multi-track mixer — duck the music volume when speech begins, and raise it back during transitions.

Step 7: Export Your Finished Episode

Click “Export” and choose your format — MP3 for audio podcasts, MP4 for video podcasts. Set quality settings (128kbps MP3 is standard for podcasts). Add episode metadata: title, description, chapter markers based on your transcript sections. Export and upload to your podcast hosting platform.

ProTips:

• Use keyboard shortcuts extensively — Ctrl+F to search transcript for specific words, making targeted edits fast
• Create chapter markers by inserting “Chapter” labels in the transcript; they export as podcast chapter markers
• Always review the edited audio by playing it back — text edits are precise but occasional transitions may sound slightly abrupt
