About these tools
Producing an audiobook means meeting each store’s rules: for ACX, RMS loudness between −23 and −18 dB, peaks under −3 dB, a noise floor under −60 dB, 192 kbps constant bitrate MP3, and a square cover of at least 2400 pixels. These tools take a book from the first take to an upload that passes.
They follow the order of a production: measure the room, record, clean up mouth noise and plosives, master, check every file, then make the retail sample, credits and cover. Your recordings never leave your device.
