fl::audio::SignalConditionerConfig

struct fl::audio::SignalConditionerConfig

Class Members
bool	enableDCRemoval = true	Enable DC offset removal (running average high-pass filter)
bool	enableNoiseGate = true	Enable noise gate with hysteresis.
bool	enableSpikeFilter = true	Enable spike filtering for I2S glitches.
i16	noiseGateCloseThreshold = 300	Noise gate close threshold (signal must fall below to close gate)
i16	noiseGateOpenThreshold = 500	Noise gate open threshold (signal must exceed to open gate)
i16	spikeThreshold = 10000	Spike detection threshold (absolute value) Samples beyond ±spikeThreshold are rejected as glitches.
