Frequently Asked Questions
How does silence detection work?
Our splitter analyzes the audio waveform to identify sections where volume falls below a threshold for a minimum duration. These silent gaps mark natural break points between segments. You can adjust both the volume threshold and minimum silence duration to fine-tune detection for your specific audio.
What if my audio has background noise?
Increase the silence threshold slider if background noise is preventing proper segment detection. A higher threshold tells the tool to ignore quieter sounds and only split on more obvious silence gaps. Experiment with different values to find what works best for your recording.
Can I split audio manually instead of using silence detection?
This tool focuses on automatic silence-based splitting. For manual control with visual selection of split points, try our full Audio Editor which offers precise waveform-based cutting and splitting.
Is there a limit to how many segments I can create?
No limit! You can split audio into as many segments as detected by the silence algorithm. The tool can handle hundreds of segments from a single file, limited only by your browser's available memory.
