struct fl::audio::detector::MusicalBeatDetectorConfig

Class Members
float	bpmSmoothingAlpha = 0.9f	BPM estimation smoothing factor (0.0-1.0) Higher values = slower BPM adaptation, more stable tempo.
float	maxBPM = 250.0f	Maximum BPM to detect (default: 250 BPM)
u32	maxIBIHistory = 8	Maximum number of inter-beat intervals to track Higher values = better BPM estimation, more memory.
float	minBeatConfidence = 0.5f	Minimum beat confidence to report a beat (0.0-1.0) Higher values = fewer false positives, may miss weak beats.
float	minBPM = 50.0f	Minimum BPM to detect (default: 50 BPM)
u32	sampleRate = 22050	Sample rate (Hz) - used for timing calculations.
u32	samplesPerFrame = 512	Samples per frame - used for timing calculations.
