Hindenburg

Hindenburg is made by Hindenburg Systems, a company based in Copenhagen, Denmark, that builds spoken-word audio editing tools for journalists, podcasters, and radio producers. Its flagship product, Hindenburg PRO, automatically levels dialogue to broadcast-standard loudness (LUFS) as clips are placed on the timeline and includes a Voice Profiler that applies EQ and compression tuned to each speaker. It also offers on-device transcription that lets editors cut audio by editing text.

Hindenburg is sold through monthly or annual subscription tiers that differ mainly in included transcription hours and access to the Soundly sound effects library, with a one-time perpetual license also available for users who prefer not to subscribe. A 30-day trial is offered with no credit card required. It targets podcast producers, radio journalists, and audiobook narrators who need fast, consistent spoken-word editing.
