Auphonic
Automatic audio post production: leveling, noise and reverb reduction, loudness and transcripts
About Auphonic
Auphonic is a web service and API that automatically processes spoken-word audio and video: it levels speakers, reduces noise, reverb and breaths, normalizes loudness to a target, and can transcribe with Whisper. It handles video files by processing the audio track and merging it back, supports multitrack productions, and scales through watch folders, a CLI and an API. Pricing is metered in hours of processed audio, with 2 free hours per month.
Pros & Cons
Pros
- Built for batch processing long recordings, with watch folders, a CLI and an API
- Pay-per-hour pricing and non-expiring one-time credits suit irregular project work
- Handles leveling and loudness targets in the same pass as noise reduction
- Accepts video files and returns them with the processed audio
- Separate controls for noise, reverb and breath reduction avoid an all-or-nothing result
Cons
- Cloud processing means uploading raw interview files
- No spectral editing or spot repair for one-off noises
- No native NLE plugin; you round-trip files through the web app or API
- Free plan adds a jingle to productions
