Tool usage guide
The Audio Silence Detector is a web-based tool that scans audio files to identify and list silent segments. It uses customizable threshold and duration settings to output start and end times in JSON format, aiding in audio editing and analysis.
Background
A podcast producer has a 30-minute episode with frequent long pauses that disrupt the listening experience.
Problem
Manually locating and cutting silence is time-consuming and can lead to missed segments.
How to use
Upload the podcast MP3 file, set the silence threshold to -40 dB and minimum duration to 1 second.
Outcome
The tool returns a JSON list of silent segments, enabling quick removal in audio editing software.
Background
An audio engineer needs to ensure a radio broadcast adheres to station rules that silence between segments must not exceed 2 seconds.
Problem
Relying on manual listening is error-prone and inefficient for long recordings.
How to use
Upload the broadcast audio file, configure threshold to -60 dB and minimum silence to 2 seconds.
Outcome
The JSON output highlights all silent periods longer than 2 seconds, facilitating compliance verification.
The tool accepts common audio formats under the audio/* category, such as MP3, WAV, and AAC.
Silence is detected when audio levels fall below the specified threshold in decibels for at least the minimum duration set.
No, the tool currently supports single file upload per session for focused analysis.
The output is a JSON array where each object contains 'start' and 'end' keys indicating time in seconds for silent segments.
Yes, the maximum file size is 200 MB to ensure efficient processing.
