opus-pure 0.2.2

//! Byte-exact comparison against the reference C libopus encoder.
//!
//! This is the strongest correctness evidence in the suite: the expected packets
//! were produced by C libopus built with `--enable-fixed-point`, encoding a
//! 440 Hz sine at each configuration. Matching them byte for byte means this
//! crate's SILK path reproduces the reference encoder's decisions exactly —
//! entropy coding, quantization, gain and LSF search included — not merely that
//! it produces something a decoder accepts.
//!
//! 22 configurations x 20 frames of 20 ms, covering narrowband, mediumband and
//! wideband at complexity 0, 1, 2, 5 and 10, and every sample rate the encoder
//! accepts. The eight at 24 and 48 kHz are the ones where SILK's encoder-side
//! resampler actually resamples; the rest run at SILK's own internal rates,
//! where it is a pass-through.
//!
//! A failure here means the encoder's *decisions* moved. That is not necessarily
//! a bug — an intentional quality change would do it — but it must never happen
//! by accident, and the diff printed on mismatch names the first differing byte.

    // Integer phase reduction keeps the `sin()` argument inside one period. That
    // is load-bearing: at large arguments the error in a libm sine grows with
    // the argument, and it grew far enough to change the i16 below on some
    // platforms before this reduction was added.
    //
    // What makes the reduced form safe is *not* that `f64::sin` agrees
    // everywhere. It does not — IEEE-754 says nothing about the accuracy of
    // transcendentals, and Apple's arm64 and x86_64 libm differ in the last
    // bits, which is why `tests/common::sin_turns` exists and why every other
    // generator in this suite avoids libm entirely. The safety here comes from
    // the i16 quantisation two lines down: a last-bit disagreement is a relative
    // 1e-16, so about 1e-12 once scaled by 16384, some twelve orders of
    // magnitude below the quantisation step. Measured: this function produces
    // byte-identical output on aarch64 and x86_64 at every rate the suite uses.
    //
    // This file keeps libm rather than switching to `sin_turns` because the
    // expected packets below were produced by C libopus encoding *this* signal.
    // Changing it would mean regenerating all 14 configurations against the C
    // reference, spending the provenance that makes this the strongest evidence
    // in the suite, to buy a margin that is already twelve orders wide.

// The configurations above all run at 8, 12 or 16 kHz, where the API rate equals
// SILK's internal rate and the encoder-side resampler is a pass-through. That
// left the ratio path — the one every 24 and 48 kHz SILK and hybrid stream goes
// through — with no byte-exact test at all, and a doubled `delay_matrix_enc`
// delay lived there undetected until it was measured against libopus by hand
// (`docs/interop-validation.md`, "The doubled SILK resampler delay").
//
// These eight close that gap. Forcing the bandwidth pins SILK's internal rate,
// so the six of them at complexity 5 cover every ratio the encoder can ask for:
// 24000 and 48000 down to each of 8000, 12000 and 16000. The resampler's output
// feeds everything downstream, so a byte-exact match here also pins the pitch
// analysis, LSF search and quantiser on resampled input rather than on input
// that merely passed through.

/// 24 kHz in, narrowband SILK out: the resampler runs 24000 -> 8000.
