Data Fields
float	threshold_dB
	Compression threshold in dB (e.g., -10.0).
float	knee_dB
	Knee width in dB for soft knee (e.g., 2.0).
float	ratio
	Compression ratio (e.g., 4.0 for 4:1 compression).
uint64_t	attack_ns
	Attack time in nanoseconds (how fast compression kicks in).
uint64_t	release_ns
	Release time in nanoseconds (how fast compression releases).
float	makeup_dB
	Makeup gain in dB (compensates for gain reduction).
float	sample_rate
	Sample rate in Hz (set during initialization).
float	envelope
	Current envelope follower state (linear, 0-1).
float	gain_lin
	Current gain multiplier (linear, calculated from envelope).
float	attack_coeff
	Attack coefficient (converted from attack_ms).
float	release_coeff
	Release coefficient (converted from release_ms).

Detailed Description

Dynamic range compressor settings and state.

Implements professional-quality dynamic range compression to prevent clipping and maintain consistent output levels. Uses sidechain input for gain reduction calculation.

COMPRESSION BEHAVIOR:

Acts above threshold_dB (no compression below threshold)
Applies compression ratio (e.g., 4:1 reduces 4dB above threshold to 1dB)
Soft knee provides smooth compression curve transition
Independent attack/release times for natural sound
Makeup gain compensates for gain reduction

Note: All time-based parameters (attack_ms, release_ms) are converted to coefficients internally for sample-by-sample processing.
