gurix	c9794cd4cd	feat(02-02): stereo mixer utilities with constant-power pan law ... - PanGains uses cos/sin constant-power pan law (D-11) - StereoFramesToInt16Bytes converts stereo frames to interleaved LE int16 bytes - clamp prevents int16 overflow for values outside [-1.0, 1.0] - All 7 mixer tests pass (pan law, byte conversion, clamping)	2026-03-26 12:02:06 +01:00
gurix	1aaa15de0b	feat(02-01): implement synth config, oscillator, and layer ... - synth/config.go: FreqConfig, HarmonicDef types; ClassFreqConfigs for all 11 traffic classes with frequencies in 60-800 Hz using musical intervals; pan positions per D-12 - synth/oscillator.go: phase-accumulator oscillator with additive harmonic synthesis and phase subtraction wrap (not math.Mod) per D-05 - synth/layer.go: EMA amplitude smoothing with tau-based alpha; whisper floor (0.03) prevents silence once class has been seen; UpdateTarget/AdvanceSample interface - All 12 tests pass (TestAllClassesHaveConfig, TestFrequenciesUnique, TestEMAAmplitudeRise, etc.)	2026-03-26 11:58:44 +01:00
gurix	bb13527281	test(02-01): add failing tests for synth config, oscillator, and layer ... - TestAllClassesHaveConfig, TestFrequenciesInRange, TestFrequenciesUnique - TestHarmonicsNonEmpty, TestPanPositionsInRange - TestOscillatorAdvance, TestOscillatorPhaseWrap, TestOscillatorDistinctFreqs - TestEMAAmplitudeRise, TestEMAAmplitudeDecay, TestWhisperFloor, TestWhisperFloorNotSeenIsZero	2026-03-26 11:57:43 +01:00
