volumecontrol-macos

macOS (CoreAudio) volume control backend for the volumecontrol crate family.

This crate provides an AudioDevice implementation backed by CoreAudio.

Note: This crate exists primarily as an implementation detail of the volumecontrol crate, which selects the correct backend automatically. If cross-platform support is not a concern, you may depend on this crate directly.

Feature flags

Feature	Description	Requires
`coreaudio`	Enable the real CoreAudio backend via `objc2-core-audio`	macOS target only

Without the coreaudio feature every method returns AudioError::Unsupported, which allows the crate to compile on any platform without the CoreAudio SDK.

Usage

[dependencies]
volumecontrol-macos = { version = "0.1", features = ["coreaudio"] }
volumecontrol-core  = "0.1"

Example

use volumecontrol_macos::AudioDevice;
use volumecontrol_core::AudioDevice as _;

fn main() -> Result<(), volumecontrol_core::AudioError> {
    let device = AudioDevice::from_default()?;
    println!("{device}");  // e.g. "MacBook Pro Speakers (73)"
    println!("Current volume: {}%", device.get_vol()?);
    Ok(())
}

Built with AI

This crate is part of the volumecontrol workspace, which was built 100% with GitHub Copilot (Claude Opus & Claude Sonnet) as an experiment in AI-driven development of a production-ready Rust crate.
