Frequently Asked Questions

What is silence threshold?

Silence threshold determines how quiet a section must be to be considered "silence." Lower values (like -60dB) detect only very quiet sections, while higher values (like -20dB) detect louder sections as silence. Start with -40dB for most recordings.

What is minimum silence duration?

Minimum silence duration determines how long a silent section must be to be removed. Shorter values (0.1s) remove even brief pauses, while longer values (2s) only remove extended silences. Use 0.5s for most podcast and voice recordings.

Will removing silence affect audio quality?

No. Silence removal only trims silent sections. The actual audio content remains unchanged and maintains full quality. The output is exported as high-quality WAV (16-bit PCM).

Can I keep some short pauses?

Yes! Enable the "Keep short pauses" option to preserve natural breathing room and pacing in speech recordings. This prevents the audio from sounding too choppy or unnatural.

Is my audio uploaded to a server?

No! All audio processing happens locally in your browser using Web Audio API. Your files never leave your device, ensuring 100% privacy.

Can I use the output commercially?

Yes, all exports are royalty-free. You can use them for personal or commercial projects.
