Tools/Audio Trimmer/Voiceover Artists
Trim silence and dead air from any audio clip.
Voiceover delivery is heavy on cleanup. Every take needs silence trimming, level matching, and chunking by line or chapter. Audiobook clients want -18 to -23 LUFS with -3 dBTP peaks; commercial work wants -16 LUFS. Browser tools cover the full delivery flow without leaving Chrome.
For voiceover artists and audiobook narrators, the typical workflow is: Record → trim breaths → normalize → split takes → deliver. The Audio Trimmer fits in that chain by handling trim silence and dead air from any audio clip.. without leaving the browser, without uploading the file, and without a watermark.

Self-release without a studio
See →ACX (Audible) requires -23 to -18 LUFS integrated, with -60 dB or quieter noise floor and -3 dBTP peaks. Most narration sits around -19 LUFS for safety inside the window.
Most clients want WAV for the master, then convert to whatever format they distribute. ACX specifically wants MP3 192 kbps CBR mono per chapter. Convert at the end of the pipeline.
