Audio Silence Remover
Make voice recordings tighter without making them sound rushed. Find long pauses, choose which gaps to shorten, and hear the difference before exporting.
Open a file to see its waveform and detected pauses.
Take the pauses out. Keep the personality.
Upload a podcast, interview, voiceover or lecture to highlight the quiet parts. Nothing is sent to a server.
Compare pauses before editing. Use the pause list to audition the original and proposed cut.
Build the preview to hear exactly what will be exported.
Review the detected pauses
Adjust settings to balance a tighter recording with natural pacing.
Silence detection is based on sound level, not speech recognition. It may interpret quiet words, breaths, or room tone as silence. Preview your edits before exporting. Multichannel audio is edited in sync; the loudest channel determines which windows are quiet.
Remove long silences without losing the natural rhythm
PixelOkay Audio Silence Remover detects quiet stretches using per-channel RMS audio levels. Choose a minimum pause length and sensitivity, then shorten them to a fixed gap or proportionally reduce longer pauses. You can keep any individual pause, customize a gap length, audition each original pause and the corresponding cleaned cut, and compare the recordings before downloading a WAV file and optional CSV edit-decision report.
Private, browser-based audio processing
Audio is decoded and processed on your device using supported browser audio APIs. This tool does not upload your recording, add a watermark, or require an account. MP3, M4A, AAC, OGG, FLAC, and other source formats are accepted only when your browser can decode them. Export is WAV PCM (16-bit or 24-bit) or WAV 32-bit float; MP3 export and speech-aware editing are not included.
How accurate is the silence detection?
Quiet speech, music, noisy backgrounds, and sudden low-volume sounds can complicate level-based detection. Use a lower sensitivity to protect soft speech; inspect and listen to proposed cuts. The tool preserves all audio channels in sync and applies a short fade at cut boundaries to reduce clicks. Long recordings require sufficient browser memory.
