Remove Silence from Audio

Remove dead air from recordings in one step: choose how quiet counts as silence and how long a pause must be, and keep a short natural gap.

How it works

Every pause quieter than the silence level and longer than the chosen length is cut.
A short pause is kept so speech still sounds natural.
Silence at the very beginning and end is trimmed too.

Quiet room recording: -50 dB. Normal: -40 dB. Background noise or hum: -30 to -35 dB.
Remove pauses longer than 0.5–1 s for speech; 2–3 s if you only want to cut long breaks.
If words get cut, choose a lower level (for example -50 dB).

Lecture and meeting recordings, podcasts, voice messages, interviews and audio books — files become shorter and quicker to listen to.

Will it cut parts of words?

With sensible settings, no. If it does, lower the silence level (for example to -50 dB) or keep a longer pause.

Can I use a video file?

Yes. Its sound is processed and saved as an audio file.

Are my files uploaded?

No. Everything runs on your device.

Which formats are supported?

MP3, WAV, M4A, AAC, OGG, OPUS, FLAC and the sound of MP4, MOV, WebM videos.

How much shorter will it be?

It depends on the recording; lectures and calls often lose 10–30%.

Does it remove background noise?

No, it only removes silent parts. Noise above the level is kept.
