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
Use Pulse when an app or assistant needs a compact waveform shape for previews, timelines, dashboards, or review workflows.
Estimate the waveform job, confirm lawful access, analyze the audio, and use the returned peaks or rendered waveform exits for previews and timeline views.
Estimates are free before paid analysis, and first-time users can try one short URL analysis before account setup. Pulse prices selected tools by audio duration using the same tool multipliers exposed by /tools: waveform 0.3 tokens/second, BPM 0.5 tokens/second, and key 0.5 tokens/second. The current token price is $0.005.
Examples are illustrative. The final estimate is shown before payment or API-key analysis and may account for selected tools, measured duration, cached analysis, failed tools, and checkout-path constraints.
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.
