Auphonic

Auphonic is an automated audio post-production web service for podcasters and creators who want professional-sounding audio without manual mastering.

Key capabilities include:

• Intelligent Leveler with dynamic range compression to balance speech, music, and multiple speakers automatically
• Noise and reverb reduction plus voice-focused processing such as AutoEQ and filtering (for example de-essing and de-plosive)
• Multitrack processing to generate an optimized mixdown, including automatic ducking, noise gate, and mic bleed removal
• Speech-to-text and shownotes using self-hosted multilingual OpenAI Whisper, with optional integrations like Amazon Transcribe and Google Cloud Speech API

Pricing: Freemium, includes 2 hours/month of processed audio on the free tier; paid plans add recurring monthly credits (S: 9h/month, L: 45h/month, XL: 100h/month) and one-time credits.

What makes it notable is its one-click, parameter-free workflow combined with publishing and automation options, including direct publishing to platforms such as YouTube, Libsyn, Blubrry, and Soundcloud, plus an API (and workflow tooling) for integrating audio post production into creator pipelines.
