What is Auphonic?
Auphonic is an automatic audio post-production web service. It analyzes audio and video content and applies processing such as loudness normalization, leveling, noise and reverb reduction, filtering, enhancement, and speech recognition. Users can create productions in the web interface, select algorithms or presets, and export results in multiple formats. The service also supports automatic publishing to external services, REST API integrations, a command-line interface, and workflow automation.
What can Auphonic do?
Speech recognition and chapter creation
Paying users can use speech recognition features for transcripts, automatic shownotes, summaries, and chapters.
Flexible production workflows
Create productions from uploaded or recorded audio and video, reuse presets, process multitrack material, and use features such as filler and silence cutting where applicable.
Encoding and publishing
Generate multiple output formats and connect productions to external services for automatic publishing and delivery.
Automation interfaces
Use the REST API, Simple API, JSON API, Auphonic CLI, webhooks, watch folders, Zapier, or n8n-supported workflows to integrate processing into scripts and media pipelines.
Use Cases
“Podcast post production”
Clean up spoken-word recordings, normalize loudness, create speech-based metadata, and prepare episodes for publishing.
“Batch processing”
Send multiple files to Auphonic through the Simple API or other automation tools when repeated manual processing would be inefficient.
“Custom media workflows”
Use presets, the full JSON API, or the CLI to control file formats, metadata, and outgoing services in a scripted production process.
“Team production billing”
Business teams can share team-account credits while keeping individual productions and presets separate from one another.
Frequently Asked Questions
Can Auphonic be used without writing code?
Yes. Productions can be created in the web service by uploading or recording audio or video and selecting algorithms or presets. Automation options are available separately for users who need scripted workflows.
What interfaces are available for automation?
Auphonic provides a Simple API for quick scripts and batch processing, a JSON REST API for detailed control, and a CLI that wraps the full API. The documentation also lists webhooks, watch folders, Zapier, and n8n integrations.
Does Auphonic support multiple output formats?
Yes. The service can encode results to multiple formats. The pricing page also states that output files such as MP3 and AAC do not change the billed processing duration.
How is processing billed?
Auphonic offers 2 hours of processed audio free each month. Paid options include recurring credits and one-time credits; recurring credits reset monthly and unused credits do not stack, while one-time credits do not expire. Billing is based on the duration of the submitted audio, with a 3-minute minimum per production.
How do team accounts work?
Business users can request team-account access. Owners can invite members and admins who use shared team credits, while team members cannot access one another’s productions or presets. The owner purchases the credits.
