The free version is ad-supported and works well for everyday audio conversion needs. Decibellum Pro is available as a one-time purchase and unlocks an ad-free experience, longer audio files, batch conversion, background conversion queue, custom output folders, filename templates, and supported audio tools such as trim, fade and normalize.

Whether you are preparing voice recordings, podcast files, music tracks or audio files for use on another device, Decibellum gives you practical controls without unnecessary complexity.
