arie

Host audio output for generated sample buffers, in Rust.

You produce interleaved PCM at whatever rate you generate it -- an emulator, a decomp's audio driver, a synth -- and arie resamples it to the output device and plays it back. Your source never has to know the device's rate or buffer size.

The API is push/queue: hand arie samples as you make them, it owns the buffering, resampling, and playback, and reports how much is queued so you can pace yourself.

use arie::{AudioPlayer, AudioConfig, SourceChannels};
use std::time::Duration;

let mut player = AudioPlayer::new(AudioConfig {
    sample_rate_hz: 32_000,
    channels: SourceChannels::Stereo,
    prebuffer: Duration::from_millis(80),
    maximum_software_queue: Duration::from_millis(250),
})?;

player.queue_interleaved_i16(&samples)?; // as you generate them

Under the hood it's a CPAL backend with continuous band-limited resampling from any source rate to the device -- including the awkward near-prime rates hardware tends to land on. There's a versioned C ABI alongside the Rust API for embedding in non-Rust hosts.
