Silence detection is based on signal level, not speech recognition. Very quiet speech or background noise may affect the results; adjust the threshold and analyze again if needed.
Your recording is analyzed locally in this browser — it is not uploaded to our servers.
What is Silence Finder?
Silence Finder scans an audio recording for stretches where the signal level drops below a chosen threshold. It is designed for podcasters cleaning up interviews, video creators reviewing dialogue, students navigating long lectures, and anyone who needs to locate pauses in a voice recording.
Instead of manually scrubbing through the whole file, you get a waveform with quiet regions highlighted and a timestamp list showing each pause's start, end and duration. Select a result to jump straight to that point and listen in context.
This tool identifies quiet sections; it does not automatically remove or alter them. That keeps the original recording intact while you decide which pauses matter. Automatic long-pause removal may be added as a separate editing workflow in the future.
Everything runs in your browser: the file is decoded and measured on your device, so private interviews, client takes and unpublished episodes never need to leave your computer. Adjust the threshold and minimum pause length until the list matches what you hear, then export the timestamps as CSV for your editor, notes or a later cut list.
How it works
02
Set the detection rules
Choose a decibel threshold and the shortest pause to report. A higher threshold detects more quiet material; a lower threshold focuses on near-silence.
03
Review the waveform
Detected pauses are shaded on the waveform and listed with exact start, end and duration timestamps. Use Listen to jump to a pause and hear it in context.
04
Export the timestamps
Download the results as a CSV file for notes, editing checklists or a later post-production workflow.
Common problems and what to do
Too many short gaps marked as pauses
Breaths, soft consonants or room noise between words can fall under a high threshold. Lower the silence threshold (more negative dB) or raise the minimum pause duration so only real dead air is listed.
Quiet speech counted as silence
Soft voices, distant mics or heavily compressed dialogue may sit near the noise floor. Move the threshold toward less sensitive values (for example −28 dB or −20 dB) and run Analyze again so spoken parts stay out of the pause list.
Long intro or outro silence missing
If the leading or trailing silence is shorter than Min pause, it will be ignored. Set a smaller minimum duration (0.3–0.5 s), analyze again, and check the first and last rows in the table or the amber regions on the waveform.
File will not analyze or decode
Unusual codecs or damaged containers can fail in the browser decoder. Convert the clip to WAV or MP3 with the site converters, then open the new file in Silence Finder. Very large files may also need a moment to decode before Analyze is ready.
Timestamps do not match your editor
Export uses seconds from the start of the file. If your NLE shows a different timeline origin or frame rate, map the CSV times relative to the same in-point you used when you imported the media. Playback in Silence Finder always jumps to the same sample positions it detected.
Background noise fills the “silence”
HVAC, traffic or a noisy room raises the floor so true pauses never drop below the threshold. Raise Min pause, try a less sensitive threshold, or clean the take first — otherwise the tool correctly reports that little true silence is present.
Frequently asked questions
How does Silence Finder detect pauses?
It checks short audio windows and marks stretches where the signal stays below your selected threshold for at least the minimum duration. It detects low-level audio, not the meaning of speech.
Does my recording get uploaded?
No. The browser decodes and analyzes the selected file on your device. Sound Booster does not need to receive your recording for this workflow.
Can I change what counts as silence?
Yes. Adjust the threshold and minimum duration, then run the analysis again. If quiet words are being marked as silence, try a lower threshold or a longer minimum duration.
Can I listen to a detected pause?
Yes. Click Listen next to a pause to jump to its start, or click a shaded region on the waveform. Playback lets you review the surrounding audio before deciding what to edit.
Can I export the pause timestamps?
Yes. Export CSV to save each detected pause's start time, end time and duration in a spreadsheet-friendly format.
Can it automatically remove long pauses?
Not in this version. Silence Finder helps you locate and review pauses without changing the source. Automatic removal is a potential future feature.
