Silence Remover

Summary

Upload an audio file, set a dB threshold, detect silent segments, and download a version with silences stripped out.

How it works

1. Upload any audio file (MP3, WAV, OGG, M4A, etc.).
2. Adjust the silence threshold in dB and minimum silence duration.
3. Click Analyze — the tool scans every audio frame for RMS amplitude below the threshold.
4. Detected silence intervals appear in a table with start time, end time, and duration.
5. Click Remove Silences to stitch non-silent segments into a new buffer and download as WAV.

Use cases

• Speed up interview audio before editing.
• Remove dead air from lecture or webinar recordings.
• Preprocess audio before transcription to reduce noise.
• Tighten voice-over recordings without manual cuts.
