Podcast Editor: Trim Dead Air

About Podcast Editor: Trim Dead Air

Podcast recordings almost always have some amount of unwanted material bookending the actual content — a countdown before recording properly starts, silence while someone gets settled, trailing dead air after the conversation wraps up. Rather than needing to specify exact clip boundaries the way a general trim tool requires, this tool is built specifically around the common podcast-editing pattern: trim a certain amount off the start, trim a certain amount off the end, keep everything in between.

You enter how many seconds to remove from the start and how many to remove from the end separately — the tool calculates the resulting keep-range automatically from the file's detected total duration, so you don't have to do that arithmetic yourself or figure out exact minute:second boundaries.

A real FFmpeg build compiled to WebAssembly performs the trim entirely inside your browser, re-encoding just the kept middle section as MP3 — the discarded intro and outro material is fully removed, not merely skipped during playback.

This complements the more general Audio Cutter tool: use Podcast Trimmer when you know how much to cut off each end rather than the exact timestamps you want to keep, and Audio Cutter when you know the precise start and end times you're targeting instead.

How it works

1. Upload your recording. Duration is detected automatically.
2. Set seconds to trim from each end. The kept range is calculated automatically.
3. Trim and download. Just the middle section, re-encoded as MP3.
