Tool usage guide
The Audio Non-Silence Detector analyzes audio files to identify and list segments containing sound, enabling efficient editing and analysis by pinpointing active parts based on customizable silence thresholds.
Background
Editing a 45-minute podcast episode with frequent silent gaps between segments.
Problem
Manually locating and cutting silent parts is tedious and prone to errors.
How to use
Upload the podcast audio file, set the silence threshold to -45 dB and minimum silence duration to 1.5 seconds.
Outcome
The tool outputs a JSON list of non-silence segments, allowing quick trimming in audio editing software.
Background
Analyzing field recordings of bird songs to study vocalization patterns.
Problem
Need to quantify active periods versus silence for behavioral research.
How to use
Upload the recording, adjust the threshold to -60 dB to capture faint sounds, and set minimum silence to 0.3 seconds.
Outcome
JSON output provides precise timestamps of non-silence segments for statistical analysis and reporting.
The tool accepts common audio formats like MP3, WAV, and others under the audio/* file type, up to 200MB.
The threshold in decibels (dB) defines what is considered silence; lower values detect quieter sounds, with a default of -50 dB.
It sets the shortest silence period to ignore brief pauses, helping to segment audio more accurately, with a default of 0.5 seconds.
The result is a JSON array containing objects with start and end times for each non-silence segment.
No, the tool currently supports one audio file per use, as specified in the input options.
