Setup

Discord Application Setup

You'll need to create a Discord application to use Rich Presence. If you want to customize the image and name, follow these steps:

1. Visit the Discord Developer Portal
2. Click "New Application" and give it a name (e.g., "Qobuz")
3. Navigate to the "General Information" tab and copy your Application ID
4. (Optional) Go to "Rich Presence" → "Art Assets" and upload any image you want, then reference it in the code

Alternatively, you can use the default Discord Application ID: 1490007914461790399

Last.fm API Key (Optional)

For album art support, you can register for a free Last.fm API key:

1. Go to the Last.fm API page
2. Fill out the application form
3. Copy your API Key once approved

Running the Application

1. Download QzRPC.exe from the releases page
2. Launch the application
3. Enter your Discord Application ID
4. (Optional) Enter your Last.fm API Key for album art
5. Click "Start"
6. Open Qobuz and start playing music

Your settings are automatically saved for future sessions.

How It Works

The application monitors your Qobuz desktop client and updates your Discord status accordingly:

• Playing: Displays track name, artist, album art, and elapsed time
• Paused: Shows the paused track with a pause indicator
• Idle: Activates after 60 seconds of inactivity or when no track is playing
