Struct FileInputBlock

pub struct FileInputBlock<S: Sample> { /* private fields */ }

Reads audio from a file into the DSP graph.

Wraps a Reader implementation to stream audio samples into the graph. Supports optional looping for continuous playback.

Implementations

impl<S: Sample> FileInputBlock<S>

pub fn new(reader: Box<dyn Reader<S>>) -> Self

Create a FileInputBlock with the Reader implementation for a particular type of audio file.

pub fn set_loop_enabled(&mut self, enabled: bool)

Set whether the audio will be looped or not.

pub fn set_position(&mut self, position: usize)

Set the position at which the audio file’s samples are being read.

pub fn get_position(&self) -> usize

Get the position at which the audio file’s samples are being read.

pub fn is_finished(&self) -> bool

Check whether the reader has finished reading every sample in the audio file.

pub fn get_reader(&self) -> &dyn Reader<S>

Get the underlying Reader implementation of the FileInputBlock.

Trait Implementations

impl<S: Sample> Block<S> for FileInputBlock<S>

fn process( &mut self, _inputs: &[&[S]], outputs: &mut [&mut [S]], _modulation_values: &[S], context: &DspContext, )
