Examples

1. Clean Up Podcast Recording

Podcast Producer

Background

A podcast episode was recorded with several seconds of silence after the host's final words.

Problem

The trailing silence makes the episode sound unpolished and could lose listener engagement.

How to use

Upload the podcast audio file, set the silence threshold to -40 dB and minimum duration to 1 second, then select MP3 as the output format.

Outcome

The episode now ends immediately after the last spoken word, providing a cleaner listening experience.

2. Trim Music Demo Silence

Musician

Background

A demo track has silence at the end due to the recording setup, which needs removal before sharing.

Problem

The silence makes the demo sound incomplete and unprofessional for submission to producers.

How to use

Use the tool to upload the demo file, adjust the threshold to -60 dB for very quiet silence, set min duration to 0.3 seconds, and export as WAV for high quality.

Outcome

The demo track is trimmed to end right after the music stops, ready for professional review.
