rvoip-codec-core 0.3.8

//! Decoder tables for AMR-NB, from the TS 26.073 reference.
//!
//! These are normative constants: the codec cannot be conformant without
//! exactly these numbers.
//!
//! # Two names, two tables
//!
//! `mean_lsf` and `dico1..3_lsf` exist in *both* `q_plsf_3.tab` and
//! `q_plsf_5.tab` with different contents. The reference gets away with the
//! collision because only one is included per translation unit; a single Rust
//! module does not, so they carry `_3` and `_5` suffixes. The generator
//! asserts the two `mean_lsf` tables actually differ, which is what catches
//! reading one file twice.
//!
//! # Not interchangeable with the wideband tables
//!
//! The cosine table here has 65 entries against wideband's 129, because
//! narrowband has ten line frequencies rather than sixteen. The interpolation
//! filter is one-sixth resolution against wideband's one-quarter. Sharing
//! either would give a codec that sounds nearly right and fails conformance.
//!
//! Generated by `tools/gen_nb_decoder_tables.py`.
