Auphonic

Auphonic is an audio analysis tool. A web based audio post production service that cleans, levels and masters recordings automatically, then optionally transcribes, cuts filler words, adds chapters and publishes the result. Built for podcasters, educators and broadcasters who need consistent output at volume.

Auphonic is a web based audio post production service that takes a raw recording and returns a finished, broadcast ready file. Upload a file or record directly in the browser, pick a preset or a set of algorithms, and the service handles noise and reverb reduction, leveling between speakers, filtering and loudness normalization on its own. The pitch is that no compressor knowledge is required: the system decides how much processing each track needs, and the operator only sets the target. The processing chain goes well past cleanup. An adaptive leveler balances speech and music, multitrack algorithms build an optimized mixdown with automatic ducking, noise gating and mic bleed removal, and a De-Esser, De-Plosive and clipping repair stage fixes common recording faults. Silence, coughs and filler words in multiple languages can be cut automatically, music segments can be trimmed out of a production, and speech recognition generates transcripts, shownotes and chapters in a shareable editor. Video output is supported too, with burned in subtitles, chapters and waveform audiograms. Because every step runs server side, the tool behaves the same on any machine. The audience is broad but specific: podcasters, educators uploading lecture recordings, video creators fixing location sound, audiobook producers who need to hit a loudness spec, and radio or broadcast teams processing material at volume. Organizations such as the BBC, iHeartRadio and Austrian broadcaster ORF appear among the named users. The strongest fit is anyone with a repeatable format who wants consistent output without hiring a mastering engineer, especially those willing to script the work through the API, CLI, watch folders or Zapier. In practice Auphonic sits between a DAW and a one-click enhancer. It is more opinionated than manual editing and far more configurable than consumer cleanup apps, and its automation layer is what separates it from podcast hosting tools that only add basic normalization. The service stops being free the moment a production matters: the monthly free allowance stamps a jingle into every free output.
