How to remove silence from audio
Use Silence Remover to cut long pauses and dead air from podcasts, voice memos, interviews, screen recordings, and lecture audio. Trimming silence keeps a recording tight and makes it easier to publish or share without manual editing.
Steps
- Drop an MP3, WAV, M4A, OGG, FLAC, or AAC file into the upload area.
- Adjust the silence threshold and minimum pause length if the defaults cut too much or too little.
- Preview the trimmed audio, then download the processed file in the same format.
Privacy note
The audio is decoded and processed in your browser using the Web Audio API. Recordings are not uploaded to an EaziApps server, which suits interviews, unpublished episodes, and personal voice notes.
Frequently asked questions
- Are my audio files uploaded to a server?
- No. Silence removal runs entirely in your browser using ffmpeg.wasm. Your audio never leaves your device, which makes the tool suitable for confidential podcast recordings and interviews.
- What audio formats are supported?
- MP3, WAV, M4A, OGG, FLAC, and AAC. The output keeps the input format when possible (lossless WAV/FLAC are preserved); unusual containers fall back to MP3 at 192 kbps.
- What do the threshold and minimum duration settings do?
- Threshold (-60 dB to -20 dB) defines how quiet audio must be to count as silence. Minimum duration (0.3 s to 5 s) is the shortest silence that gets cut — shorter pauses are kept so speech rhythm stays natural.
- What is the difference between Remove and Shorten mode?
- Remove cuts detected silences entirely. Shorten compresses each long silence down to the minimum duration, preserving natural pacing — often better for conversational podcasts where some breathing room helps comprehension.
- Why is the result clipping the start of words?
- The threshold is too high (too strict). Lower it to a more negative value like -45 dB or -50 dB, or raise the minimum silence length so short pauses between words are not treated as silence.
- How long can my audio file be?
- There is no hard limit, but ffmpeg.wasm holds the file in memory. Files under 100 MB (roughly 1-2 hours of podcast audio at typical bitrates) process reliably on most laptops.
