Sound generation in the browser using Web Audio and C#
summary
Shows how the Web Audio API is used from C# via Blazor wrappers to generate and analyze sound: creates an AudioContext with an OscillatorNode routed through a GainNode to speakers, starts/stops tones with randomized frequencies, and uses an AnalyserNode to compute a frequency spectrum and an averaged peak (~796). Demonstrates a new MediaStreamRecording wrapper (built last week) to record a click, retune it to 440 Hz, and reuse the sample as a keyboard instrument; library covers ~71% of the spec.
