pub const IMPULSE_AMPLITUDE: f32 = 0.95;Expand description
Peak amplitude of the synthetic test impulse written to the output ring buffer.
A near-full-scale value is used so the echo stands well above the noise floor even after
passing through lossy physical paths. The detection threshold is clamped to at most
IMPULSE_AMPLITUDE * 0.5 so that a valid echo is always detectable.
