Typedef Documentation

AudioFill

using rex::apu::AudioFill = MoveOnlyFunction<void(std::span<f32> samples, u32 channels)>

Fills the samples the device is about to play. The device calls it from its own thread.

Parameters

samples

Interleaved 48 kHz f32 in host byte order, written in full.

AudioFrame

using rex::apu::AudioFrame = std::span<const f32, kAudioFrameSamples>

One frame in host byte order, channels in the order FL, FR, C, LFE, SL, SR.

Variable Documentation

kAPU

memory::Tag rex::apu::kAPU {4}

inlineconstexpr

The tag of audio emulation and the audio drivers. The audio provider names it "APU".

kAudioFrameChannels

u32 rex::apu::kAudioFrameChannels = 6

inlineconstexpr

A submitted frame holds 6 channels one after another, 256 samples each at 48 kHz.
