Struct FlacDecoderWrap

pub struct FlacDecoderWrap<'a> {
    pub downmixer: Downmixer,
    /* private fields */
}

A wrapper for the WaveReader to decode FLAC audio encapsulated in the WAV file.

Fields

downmixer: Downmixer

The downmixer for multiple channels audio to decode into 2 or 1 channels

where S: SampleType,

fn get_channels(&self) -> u16

Get num channels

fn get_cur_frame_index(&mut self) -> Result<u64, AudioReadError>

Get current frame index.

fn seek(&mut self, seek_from: SeekFrom) -> Result<(), AudioReadError>

Seek to a specific audio frame. An audio frame is each channel has one sample.

fn decode_frame(&mut self) -> Result<Option<Vec<S>>, AudioReadError>

Decode one audio frame. An audio frame is each channel has one sample. This method supports > 2 channels.

fn decode_stereo(&mut self) -> Result<Option<(S, S)>, AudioReadError>

Decode a stereo sample with left and right samples, if the audio has > 2 channels, this method fails.

fn decode_mono(&mut self) -> Result<Option<S>, AudioReadError>

Decode a mono sample, multiple channels will be mixed into one channel.

fn set_downmixer(&mut self, downmixer: &Downmixer)

Set the downmixer

fn get_downmixer(&self) -> Option<Downmixer>

Get the downmixer

fn decode_frames( &mut self, num_frames: usize, ) -> Result<Vec<Vec<S>>, AudioReadError>

Decode multiple audio frames. This method supports > 2 channels.

fn decode_monos(&mut self, num_monos: usize) -> Result<Vec<S>, AudioReadError>

Decode multiple mono samples, multiple channels will be mixed into one channel.

fn decode_stereos( &mut self, num_stereos: usize, ) -> Result<Vec<(S, S)>, AudioReadError>

Decode multiple stereo samples with left and right samples, if the audio has > 2 channels, this method fails.
