Auphonic
Graz, Austria
What it is
Auphonic is an automated audio post-production service for podcasts, broadcasts, radio, interviews, audiobooks, lectures, and other audio or video work. Its processing can reduce noise and reverb, adjust levels, filter and enhance sound, meet loudness specifications, and automatically cut filler words, coughs, and silence. Multitrack processing builds mixdowns with automatic ducking, noise gates, and mic-bleed removal. The service also provides multilingual speech-to-text, automatic shownotes and chapters, and a shareable transcript editor. It supports common audio and video formats, waveform audiograms, metadata, and styled subtitles burned into video. Integrations include storage, publishing, and automation services; workflows can also use an API, CLI, watch folders, or batch productions. The free plan is free and includes two hours monthly, but free multitrack productions must be under 20 minutes and exclude speech recognition and several automation features. Billing has a three-minute minimum per production. Audio and API productions are deleted after 21 days, and video productions after seven days.
