## What it is
A virtual audio driver (HAL plugin) for macOS that creates a proxy audio output device forwarding all audio to another output device. It lets users control the volume of external audio interfaces via macOS system volume controls.

## Use cases
- control volume of a DAC or audio interface that ignores macOS volume keys
- route system audio through a virtual device to another output
- use the menu bar volume slider with external audio hardware
- redirect all macOS audio output to a specific device

## When to choose
- your external audio interface doesn't respond to macOS volume controls
- you need a virtual audio device that forwards to another output on macOS

## When to avoid
- you need multi-channel (>2) audio proxying
- you're on Linux or Windows
- you need low-latency with very small buffers (risk of pops and crackles)
