A cli tool for cutting a long audio into segments by silence.
Project description
voicecut
A cli utility for splitting a long audio file into shorter chunks based on moments of silence. It is useful for preprocessing audio before performing speech-to-text on it.
Installation
Through uv (recomended)
uv tool install voicecut
Through pip
pip install voicecut
Usage
Split audio files from the command line:
voicecut audio.mp3 [OPTIONS]
Options:
--segment-length FLOAT: Target segment length in seconds (default: 600)--segment-delta FLOAT: Allowed deviation from segment length in seconds (default: 30)--silence-thresh-mode {mean, max, auto}: Mode to determine the silence threshold. 'mean' uses the audio's average dBFS, 'max' uses the audio's peak dBFS, and 'abs' treats --silence-thresh-delta as an absolute dBFS value. For 'mean' and 'max', the computed value is adjusted by --silence-thresh-delta; for 'abs' the delta is used directly as the threshold.--silence-thresh-delta FLOAT: Silence threshold delta in dB (default: -4)--min-silence-len FLOAT: Minimum silence length in seconds (default: 0.5)--output-dir PATH: Output directory for split segments (default: current directory)
Example:
voicecut audio.mp3 --segment-length 600 --output-dir ./segments
Development
It is recomended to use uv toolset for development.
Testing
There are unittests available in the tests/ directory.
uv run pytest
