Struct GlobalConfig 

pub struct GlobalConfig {
    pub sample_rate: u32,
    pub oversample: u32,
    pub fft_size: usize,
    pub warmup_trim_ms: f64,
    pub settle_ms: f64,
}

Global settings for all tests.

Fields

sample_rate: u32

oversample: u32

fft_size: usize

warmup_trim_ms: f64

Steady-state warmup trim: milliseconds to discard from the start of BOTH the WDF and golden signals before computing any metric (RMS, peak, THD, spectral). Trimming happens at metric time; stored goldens are unaffected.

Default: 10 ms. Per-test overrides via TestCase::warmup_trim_ms.

Window math (default settings: 96 kHz × 4× = 384 kHz internal):

• 10 ms trim = 3840 samples removed.
• Shortest signal = 50 ms = 19200 samples → 15360 remain (40 ms).
• 1 kHz fundamental: 40 cycles in remaining window — adequate for both THD (Blackman window needs ~5 cycles) and spectral resolution (25 Hz/bin).

settle_ms: f64

Steady-state SETTLE window in milliseconds: how long a coupling-cap / bias network must charge before its output reaches steady state. Goldens (and the WDF side) are generated long enough to settle, and settle_ms of the head is discarded so EVERY metric is computed on the settled tail.

Why this is distinct from warmup_trim_ms: a 10 ms trim only skips a fast turn-on transient. An AC-coupled output with a 10 µF cap into a 10 k load has RC ≈ 100 ms, so it needs ~5–10 τ (0.5–1 s) to settle — measuring before that captures the DC charge-up ramp, not the gain. Default 500 ms (= 5 τ for a 100 ms-RC coupling cap). Slow circuits (e.g. the BA283 with two 10 µF caps) override per-test via TestCase::warmup_trim_ms.

The conservative default does not shorten any existing window: when the settle exceeds the signal length the trim clamps to the full slice, so short fast-settling tests are unaffected.
