Remove Silence from WAV Files
WAV files hold uncompressed audio, which makes them the best source for editing. This page removes silence from WAV files without adding any compression: the remaining samples are copied exactly as they were.
That makes it a good fit for studio takes, field recordings, sample libraries and voiceover masters that you intend to keep at full quality.
Where it helps
- Studio voice takes: Remove the silent tail and gaps between takes before mastering.
- Field recordings: Cut long quiet stretches while you wait for the interesting sound.
- Samples and loops: Trim empty space at the start of a sample so it triggers instantly.
Tips for the best result
Export WAV for the cleanest result. The exported file is 16-bit PCM at the same sample rate as your source.
For samples, use a very short minimum silence (0.05 s) and 0 ms padding to get tight edges.
Which settings should I use?
- Default: -45 dB threshold, 0.1 s minimum silence. A balanced first try for most clean audio.
- Podcast: -40 dB, 0.4 s. Removes long pauses and keeps short natural ones.
- Voice note: -42 dB, 0.25 s. Good for phone recordings and WhatsApp messages.
- AI voice / TTS: -50 dB, 0.15 s. Generated speech is very clean, so a low threshold is enough.
- Lecture: -38 dB, 0.5 s. Handles room noise and long thinking pauses in classes and talks.
Frequently asked questions
Does the tool keep the sample rate?
Yes. The output uses the same sample rate and channel count as the decoded source.
Is the export 16-bit or 24-bit?
The WAV export is 16-bit PCM. If you need 24-bit or 32-bit float, use a dedicated audio editor for the final render.
Can it handle stereo files?
Yes. Silence is detected using all channels together, so both sides are cut at the same points and stay in sync.
Will it work with large WAV files?
Yes, as long as your browser has enough memory. A 10-minute stereo 44.1 kHz WAV is about 100 MB.
Can I convert to MP3 at the same time?
Yes. After processing, choose Download MP3 to get a compressed copy.
