#include <minidsp.h>

Data Fields
double	weights [MD_VAD_NUM_FEATURES]
	Per-feature weights for scoring.
double	threshold
	Decision threshold (0.0–1.0).
unsigned	onset_frames
	Consecutive above-threshold frames before speech.
unsigned	hangover_frames
	Extra speech frames after score drops.
double	adaptation_rate
	EMA rate for min/max tracking (0.0–1.0).
double	band_low_hz
	Lower bound of speech band (Hz).
double	band_high_hz
	Upper bound of speech band (Hz).

Detailed Description

Parameters for the VAD detector.

All fields are caller-tunable. Use MD_vad_default_params() to populate with sensible defaults before adjusting individual fields.
