gurix	7f6471426f	feat(05-01): wire waveform resolution into NewLayer at construction time ... - NewLayer resolves WaveformPresetHarmonics when cfg.WaveformType != WaveformCustom - Preset harmonics stored in Layer.Config so AdvanceSample uses them unchanged - WaveformCustom path preserves existing hand-tuned harmonics (backward compatible) - TestNewLayerResolvesWaveformPreset: verifies preset fills harmonics on construction - TestNewLayerPreservesCustomHarmonics: verifies hand-tuned harmonics are untouched - TestSineRegressionVsCustomHarmonics: verifies WaveformSine == {Ratio:1,Amp:1.0} - All 41 synth tests pass, encode tests unaffected	2026-03-26 17:34:45 +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
