Shorten pauses without removing natural spacing
This tool detects long quiet sections in TTS and spoken audio, then reduces them to a pause you choose. Upload a file, preview it, adjust the three controls, and process a copy while keeping the original untouched.
Understanding the silence controls
Threshold decides how quiet audio must be to count as silence. A value near -30 dB treats more low-level sound as silence, while -50 dB reacts only to quieter sections. Minimum silence sets how long a quiet section must last, and pause to keep preserves breathing room after processing.
Good uses and checks
It works well for tightening TTS narration, lectures, and voice drafts. Common inputs include MP3, WAV, and M4A; the result is encoded as MP3. Background noise can affect detection, so preview the output and make sure word endings remain intact. Processing stays inside your browser.
