API Reference / CreateRealtimeBpmAnalyzerOptions

Type Alias: CreateRealtimeBpmAnalyzerOptions

type CreateRealtimeBpmAnalyzerOptions = RealTimeBpmAnalyzerParameters & {
  processorUrl?: string | URL;
};

Defined in: core/types.ts:201

Options accepted by createRealtimeBpmAnalyzer: the analyzer parameters plus where to load the worklet from.

Type Declaration

Name	Type	Description	Defined in
processorUrl?	string | URL	URL of the processor file handed to audioWorklet.addModule (default: an inlined blob: URL)	core/types.ts:203

Remarks

By default the processor is loaded from a blob: URL built from an inlined copy, so no extra file has to be served. Pages whose Content Security Policy refuses blob: scripts, and Manifest V3 extensions (whose CSP cannot allow blob:), set processorUrl to a copy of the published realtime-bpm-analyzer/processor file served from their own origin instead.

Example

// MV3 extension, with dist/realtime-bpm-processor.js copied into the extension build
const analyzer = await createRealtimeBpmAnalyzer(audioContext, {
  processorUrl: chrome.runtime.getURL('realtime-bpm-processor.js'),
});
