Peak extraction

Waveform Analysis API for Audio Visualization

Use Pulse when an app or assistant needs a compact waveform shape for previews, timelines, dashboards, or review workflows.

Who this is for

What Pulse returns

  • waveform peak data
  • channel and sample metadata when available
  • status links for SVG/PNG exits
  • job status and selected-tool cost details

Example workflow

Estimate the waveform job, confirm lawful access, analyze the audio, and use the returned peaks or rendered waveform exits for previews and timeline views.

Pricing and estimates

Estimates are free before paid analysis. One analysis up to 5 minutes. URL only; BPM, key and waveform. Up to two queued attempts if the first fails. Rights, permission, lawful access, or another legal basis required. Pulse prices selected tools by audio duration using the same tool multipliers exposed by /tools: waveform 0.06 tokens/second, BPM 0.1 tokens/second, and key 0.1 tokens/second. The current token price is $0.005.

Examples are estimates. Review the returned estimate before payment or API-key analysis. Final charges depend on measured duration, completed tools, cached analysis and checkout-path constraints.

Rights-aware analysis boundary

Pulse is designed for audio the user has rights, permission, lawful access, or another legal basis to submit. Agents and apps should confirm that before analysis. Pulse does not provide transcription, stem separation, mastering, loudness correction, chord transcription, or track structure segmentation in v1.0.

Pulse is designed to make audio analysis auditable. Each analysis flow should make clear which URL was submitted, which tools were selected, what the estimate was, when rights confirmation was given, and whether the job completed, partially completed, failed, or expired.
