Tips for better results
- •Start with a conservative threshold if the speaker has soft endings or quiet breaths.

Silence Trimmer FAQ
Does this split the audio into many sections?
No. This page trims the beginning and end based on silence settings. It does not create multiple output segments.
Is my audio uploaded to a server?
No. The processing happens in your browser, so the source file stays on your device.
Which formats can I upload?
Most common browser-decodable formats are supported, including MP3, WAV, M4A, FLAC, OGG, and many AAC-based files.
When should I export WAV instead of MP3?
Choose WAV if you plan to keep editing or chain more processing afterward. MP3 is better for quick sharing and review.
