Frequently Asked Questions
Everything people ask before using remove silence.
Start with −35 dB and a minimum gap of 0.5 seconds. That removes genuine dead air while leaving the natural pauses that make speech easy to follow. Lower the threshold if background hiss is being kept, raise it if breaths are being cut.
No. AudioKit keeps a small configurable pad of silence around each detected sound, so consonants and breaths at the edge of a phrase are preserved rather than clipped.
It is designed for speech. Music rarely has true silence, so the tool will have little to remove — for music, Trim Audio or Change Speed will be more useful.
No. AudioKit processes every file locally in your browser using WebAssembly. Your audio is never transmitted to a server, never stored, and never seen by anyone but you. You can even disconnect from the internet after the page loads and the tools keep working.
You can open MP3, WAV, OGG, FLAC, AAC and M4A files. Output formats depend on the tool — Convert Audio can write MP3, WAV, OGG, FLAC, AAC and M4A.
