Struct AudioContext

pub struct AudioContext<'a> {
    pub(crate) environment_callback: &'a retro_environment_t,
    pub(crate) interfaces: Arc<RwLock<InterfaceList>>,
    pub(crate) audio_sample_batch_callback: &'a retro_audio_sample_batch_t,
    pub(crate) audio_sample_callback: &'a retro_audio_sample_t,
}

Functions that are safe to be called in Core::on_write_audio.

For a description of the callbacks see CoreWrapper.

Fields

environment_callback: &'a retro_environment_t

interfaces: Arc<RwLock<InterfaceList>>

audio_sample_batch_callback: &'a retro_audio_sample_batch_t

audio_sample_callback: &'a retro_audio_sample_t

Implementations

impl AudioContext<'_>

pub fn batch_audio_samples(&self, samples: &[i16])

Renders multiple audio frames in one go if AudioContext::audio_sample_batch_callback has been set.

One frame is defined as a sample of left and right channels, interleaved. I.e. let buf: [u16; 4] = [ l, r, l, r ]; would be 2 frames.

Only one of the audio callbacks must ever be used.

pub fn queue_audio_sample(&self, left: i16, right: i16)

Renders a single audio frame if AudioContext::audio_sample_callback has been set. Should only be used if implementation generates a single sample at a time. Format is signed 16-bit native endian.

Only one of the audio callbacks must ever be used.
