Unsafe get buffer for offline rendering

pub fn buffer(&self) -> &Vec<Vec<f32>>

Unsafe get buffer for offline rendering

pub fn handle(&self) -> &Shared<AudioFileProcessorHandle>

pub fn play(&self)

Resume playback

pub fn pause(&self)

Pause playback

Trait Implementations

impl AudioProcessor for AudioFileProcessor

fn prepare(&mut self, context: &mut AudioContext)

Prepares for playback

Note: Currently this will load the audio file on the audio-thread. It’d be an interesting exercise to perform this on a background thread.

type SampleType = f32

fn process( &mut self, _context: &mut AudioContext, data: &mut AudioBuffer<Self::SampleType>, )

Process a block of samples by mutating the input AudioBuffer
