<!-- SECTION: Summary -->
## What is AES67 Test Tone?

AES67 Test Tone is a utility designed for troubleshooting and experimenting with AES67 audio-over-IP installations. It generates a modulating 1kHz and 500Hz sine wave and broadcasts it as an AES67 multicast stream via the SAP protocol.

<!-- SECTION: Key Features -->
## Key Features

- **Modulating Sine Wave Generator**: Outputs a 1kHz tone for 500ms followed by a 500Hz tone for 500ms.
- **SAP Protocol Support**: Publishes the audio stream using the Session Announcement Protocol for automatic discovery by compatible network devices.
- **PTPv2 Clock Referencing**: Includes a non-specific traceable PTPv2 clock reference within the SDP for stream synchronization.

<!-- SECTION: Target Audience -->
## Who is it for?

Audio engineers and network technicians working with AES67 audio-over-IP infrastructure.
