Struct codec2::Codec2

pub struct Codec2 { /* fields omitted */ }

A Codec2 object for encoding or decoding audio

Implementations

impl Codec2

pub fn new(mode: Codec2Mode) -> Self

Creates a new Codec2 object suitable for encoding or decoding audio

pub fn bits_per_frame(&self) -> usize

The number of bits in an encoded (compressed) frame; 64 for the 3200 bitrate, 48 for 2400.

pub fn samples_per_frame(&self) -> usize

How many samples an encoded (compressed) frame represents; generally 160 (20ms of speech).

pub fn encode(&mut self, bits: &mut [u8], speech: &[i16])

Encodes speech samples at current bitrate into bits_per_frame()/8 rounded up output bytes. For MODE_3200, this is 64 bits or 8 bytes, for MODE_2400, it's 48 bits (6 bytes).

pub fn decode(&mut self, speech: &mut [i16], bits: &[u8])

Decodes bits_per_frame() compressed bits into samples_per_frame() speech samples. For MODE_3200, the input is 64 bits or 8 bytes, for MODE_2400, it's 48 bits (6 bytes).

Trait Implementations

impl Clone for Codec2

pub fn clone(&self) -> Codec2

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Codec2

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

Formats the value using the given formatter.
