Extract structured data from audio files
Extract structured data from audio files with transcripts, speaker labels, timestamps, source citations, and schema-defined JSON output.
Use the same workflow from code, agents, or n8n
When an automation moves from prototype to production, you should not have to rebuild it for every environment. Iteration Layer lets scripts, agents, and n8n workflows call the same European AI workflow runtime.
EU AI workflow runtime
Run document, image, and file steps through one EU-hosted workflow layer with shared API conventions and billing.
Agent-ready by design
Expose the same document and image actions to MCP tools and Claude Code skills, then reuse the API contract when workflows graduate into scripts or automations.
Verified n8n node
Install the verified Iteration Layer node in n8n, then route documents and generated files through the same provider from visual workflows.
Three steps to your first extraction
Send your audio file
Pass an audio file via URL or base64. Common audio formats are supported.
Define a schema
Describe the fields you want to extract — speaker turns, action items, key decisions, summaries. The audio is transcribed internally and your schema is applied to the result.
Get structured data
Receive JSON with extracted fields, confidence scores, and citations that link each value back to the transcript with timestamps. Pipe the output directly into a document or spreadsheet.
Speaker Detection
Each speaker in the recording is automatically identified and labeled. Schema fields can target individual speakers — useful for meeting notes, interviews, and sales calls.
Timestamped Segments
Every extracted value includes a source citation with timestamps so you can verify where a value came from without scrubbing through the audio.
Automatic Language Detection
No language configuration needed. The model identifies the spoken language automatically.
Schema-Driven Results
Define typed fields — summaries, action items, decisions, named entities — and get structured JSON back. No transcript parsing, no prompt engineering.
Built-In Trust Scores
Every extracted value includes a confidence score and a source citation pointing to the transcript. Route low-confidence results to human review.
European by design
Your data is processed on EU-hosted infrastructure and never stored beyond temporary logs. Zero data retention, GDPR-compliant workflows, and a Data Processing Agreement are available for every customer. Learn more about our security practices .
EU-hosted core processing
Application and processing infrastructure runs in Europe, with provider-scope ISO 27001 and BSI C5 evidence documented for procurement reviews.
Zero data retention
Customer files and processing results are not stored after the request. Usage logs are retained for 90 days and automatically deleted.
Clear answers for security teams
Give reviewers the answers they need up front: where files are processed, what is retained, which subprocessors are involved, and how AI inputs, outputs, review gates, and audit records move through each workflow.
Pricing
Start usage-based. Switch to a subscription when your volume becomes predictable.
Usage-based
Graduated pricing. Your effective rate decreases automatically as monthly usage grows.
- No monthly commitment
- Pay only for credits used
- Automatic volume discounts as usage grows
Predictable volume
Fixed recurring credit packs with lower effective credit prices for steady usage.
- Lower effective per-credit prices
- Fixed recurring credit packs
- Predictable monthly budget
