Best fit

Use Beatlyze when the job is clear.

Use this page when you are building a music product that needs metadata extraction without running DSP workers, queues, storage, billing, and API infrastructure yourself.

Music fields BPM + key

Core signals for playback, search, and matching.

Technical fields LUFS + duration

Useful for QA, normalization review, and catalog hygiene.

Semantic fields Mood + genre

Broad hints for discovery and editorial workflows.

Reliability Confidence

Every product can choose how much automation to allow.

Workflows

Where this API earns its keep.

These are product workflows where Beatlyze can replace manual tagging, brittle scripts, or an internal audio worker backlog.

Workflow

Music catalog enrichment

Add analysis output to tracks so users can filter, sort, and search with richer metadata.

Workflow

Recommendation features

Use BPM, key, mood, and genre hints as ingredients in your own ranking and recommendation logic.

Workflow

Operational review

Use confidence and review flags to decide which tracks need a human pass before publishing metadata.

Decision points

A practical API contract for product teams.

Beatlyze is intentionally explicit about lifecycle state, uncertainty, and integration boundaries.

Focused API surface

Beatlyze is narrower than a generic ML platform and easier to integrate than building audio infrastructure yourself.

Practical outputs

The result is shaped for product decisions: numbers, labels, confidence, sections, and explicit job status.

FAQ

Common questions before integration.

Short answers for developers deciding whether Beatlyze fits the product they are building.

What is the difference between music analysis and audio metadata?

Audio metadata describes the fields. Music analysis is the workflow that extracts those fields from tracks and returns them as API output.

Can Beatlyze detect genre?

Beatlyze returns broad genre suggestions and genre confidence. Treat these as product hints, not editorial truth.

How do I start?

Run the anonymous demo, create a free API key, submit a public URL or upload, then poll the returned job ID.
