Implementations

impl CeltDecoder

pub fn new(mode: &'static CeltMode, channels: usize, sampling_rate: i32) -> Self

Create a CELT decoder. sampling_rate is the API sampling rate (8000–48000); the decoder always operates at 48 kHz internally and decimates by resampling_factor(sampling_rate) on output.

pub fn decode( &mut self, compressed: &[u8], frame_size: usize, pcm: &mut [f32], ) -> usize

pub fn set_stream_channels(&mut self, channels: usize)

Set the number of channels coded in the stream (libopus CELT_SET_CHANNELS). A mono stream plays on both channels of a stereo decoder; a stereo stream is downmixed by a mono one.

pub fn reset_state(&mut self)

Reset all decoder state (equivalent to libopus OPUS_RESET_STATE). Used at SILK↔CELT mode transitions to avoid cross-mode artifacts.

pub fn decode_with_start_band( &mut self, compressed: &[u8], frame_size: usize, pcm: &mut [f32], start_band: usize, ) -> usize

pub fn decode_from_range_coder( &mut self, rc: &mut RangeCoder, total_bits: i32, frame_size: usize, pcm: &mut [f32], start_band: usize, ) -> usize

pub fn decode_from_range_coder_with_band_range( &mut self, rc: &mut RangeCoder, total_bits: i32, frame_size: usize, pcm: &mut [f32], start_band: usize, end_band: usize, ) -> usize
