Auphonic

Auphonic is a web service for processing spoken-word audio and video, from cleanup and multitrack mixing to transcription and delivery. It best suits podcasters, broadcasters and publishers with recurring production needs. Its range is a strong fit for end-to-end workflows, but short media-retention windows and duration-based billing deserve attention.

Overview

Founded in 2013 and based in Graz, Austria, Auphonic combines audio post-production with tools for transcription, subtitles, publishing and automation. It processes audio and video in batches, so it is better suited to preparing complete productions than making quick, live adjustments.

Its reach is broader than noise removal alone: users can clean recordings, create multitrack mixdowns, generate transcripts and chapters, and connect productions to storage or publishing services. That breadth is useful for teams trying to consolidate steps; occasional users may find the paid quotas and production-based minimum charge less attractive.

Key features

Cleanup and multitrack mixing

Processing includes noise and reverb reduction, intelligent leveling, filtering, enhancement and loudness targeting. Automatic cutting can remove filler words, coughs and silence, reducing some manual editing. For multitrack recordings, Auphonic builds mixdowns with automatic ducking, noise gates and mic-bleed removal. These controls make it relevant to interviews and other multi-microphone work, not just single-voice cleanup.

Transcription, video and delivery

Multilingual speech recognition supports transcripts, automatic shownotes and chapters, with a shareable transcript editor. Recognition combines a self-hosted multilingual Whisper model with external services. Auphonic also supports common audio and video formats, waveform audiograms, metadata, chapters and burned-in styled subtitles. The combination can keep several production tasks together, though the free account excludes multilingual recognition, shownotes and chapters.

Integrations and automation

Connections include FTP and SFTP, Dropbox, Google Drive, OneDrive, Amazon S3, YouTube, Libsyn, Spreaker, SoundCloud, PodBean, Zapier, n8n and speech-recognition providers. The developer API, CLI, watch folders and batch productions support automated workflows. The free CLI has static binaries for Linux, macOS and Windows; free accounts do not include watch folders or batch productions.

Pricing

Auphonic is freemium, with a free trial also offered. Plans are measured in processed audio duration, and each production has a three-minute minimum charge. That minimum can make very short jobs consume more quota than their actual length suggests.

The free plan is a practical starting point for light use, but its two-hour allowance does not stack, and free productions are limited to multitrack work under 20 minutes. It also omits multilingual recognition, automatic shownotes and chapters, watch folders and batch productions. S through XL scale monthly capacity for regular production, with yearly billing; XXL is aimed at much higher volume, but its monthly credits expire at reset. Monthly and one-time plans include standard support, while yearly and business plans include priority support. Free plans include basic support.

Platforms

Auphonic supports web, API, Linux, macOS and Windows. The CLI is specifically available as free static binaries for Linux, macOS and Windows, which gives technical users a route to command-line workflows alongside the web service.

Who it's for

Auphonic is a good fit for podcasters, radio and broadcast producers, audiobook makers, educators and publishers handling recurring spoken-word recordings. Multitrack tools, transcripts and delivery integrations are especially useful when production involves several sources or repeated publishing steps. A one-off user needing only a quick voice cleanup may be better served by a narrower tool.

Organizations handling sensitive media should account for retention and hosting: audio and API productions and their media are permanently deleted after 21 days, while video productions are deleted after 7 days. Data is stored primarily on servers in Germany, with Cloudflare R2 used for media storage and delivery; EU users' media remains in EU jurisdiction. Auphonic states that it complies with the EU General Data Protection Regulation worldwide, and paying customers can request a Data Processing Agreement.

Pros and cons

Pros

• Broad spoken-word workflow: Cleanup, multitrack mixdowns, transcription, subtitles and delivery integrations can sit in one production service.
• Automation options: API, CLI, watch folders and batch productions support repeatable pipelines, although several are excluded from free accounts.
• Clear capacity tiers: Monthly quotas range from 2 h/month free to 250 h/month on XXL, helping match spend to production volume.
• EU data handling: Germany-based primary hosting and EU-jurisdiction media for EU users may suit organizations with regional data requirements.

Cons

• Free-tier exclusions: Free users lack multilingual speech recognition, shownotes and chapters, watch folders and batch productions, limiting its value as a complete workflow.
• Short retention: Media is permanently deleted after 21 days for audio and API productions and 7 days for video, so teams need their own archival process.
• Minimum billing duration: The three-minute minimum per production can use quota quickly for short files.
• Non-rolling XXL credits: Unused monthly credits do not carry over, which can penalize uneven production schedules.

Verdict

Choose Auphonic if you need more than noise reduction: it brings cleanup, multitrack processing, transcription and workflow automation together for recurring spoken-word production. Look elsewhere if you need only a quick one-off adjustment, cannot work within the three-minute minimum, or require media to remain stored beyond its 7- or 21-day retention period.
