}

One fully decoded regular SILK frame: every Table-5 bitstream symbol consumed and the §4.2.7.5 LSF → LPC chain run.

Fields

signal_type: SignalType

§4.2.7.3 signal type.

qoff_type: QuantizationOffsetType

§4.2.7.3 quantization-offset type.

gains: SubframeGains

§4.2.7.4 per-subframe quantization gains (log_gain ∈ 0..=63).

lsf_stage1: u8

§4.2.7.5.1 normalized LSF stage-1 index I1 ∈ 0..32.

nlsf_q15: [i16; 16]

The §4.2.7.5.4 stabilized normalized-LSF vector for the current frame (n2_Q15[]), carried forward as the next frame’s §4.2.7.5.5 interpolation base. Only 0..d_lpc entries are valid.

d_lpc: usize

d_LPC (length of Self::nlsf_q15): 10 for NB/MB, 16 for WB.

lsf_interp_q2: Option<u8>

§4.2.7.5.5 interpolation factor w_Q2 ∈ 0..=4 for a 20 ms frame; None for a 10 ms frame (no first-half split).

lpc_second_half: LpcQ12

The final stable §4.2.7.5.8 Q12 LPC filter for the second half of the frame (derived from the stabilized current-frame NLSF).

lpc_first_half: Option<LpcQ12>

The final stable §4.2.7.5.8 Q12 LPC filter for the first half of a 20 ms frame (derived from the interpolated n1_Q15[]); None for a 10 ms frame, which uses Self::lpc_second_half throughout.

ltp: LtpParameters

§4.2.7.6 LTP parameters (voiced frames only; empty otherwise).

lcg_seed: u8

§4.2.7.7 LCG seed 0..=3.

excitation: Excitation

§4.2.7.8 quantized excitation e_Q23[].

stereo_pred: Option<StereoPredictionWeights>

§4.2.7.1 decoded stereo prediction weights (Q13), present only on the mid channel of a stereo Opus frame (when SilkFrameConfig::stereo is Some); None for a mono frame.

mid_only_flag: Option<bool>

§4.2.7.2 decoded mid-only flag, present only when the stereo context had StereoHeaderContext::has_mid_only_flag set; Some(true) means the side channel of this interval is skipped.

Trait Implementations

impl Clone for SilkFrameDecoded

fn clone(&self) -> SilkFrameDecoded

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SilkFrameDecoded

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for SilkFrameDecoded

fn eq(&self, other: &SilkFrameDecoded) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
