🎵 Speed-Sensitive Volume Plugin for Assetto Corsa

⚠️ WE HIGHLY RECOMMAND USING THIS EXTERNAL VERSION

Automatically adjust music volume based on your car's speed
A modern solution for immersive racing experiences

Volume response curves for different algorithms (simulated data, max speed 150 km/h)

🚀 Features

• 📊 4 Volume adjustment algorithms
• 🎚️ Real-time speed/volume visualization
• ⚙️ In-game configuration menu
• 🔍 Automatic music app detection
• 🛠️ Customizable speed/volume ranges
• ✅ Supports Spotify, YouTube Music, VLC, etc.

📦 Installation

Setup

1. Download the project and place the folder SpeedSensitive_Volume in your game directory (e.g., C:\Program Files (x86)\Steam\steamapps\common\assettocorsa\) and inside the folder apps\python
   (C:\Program Files (x86)\Steam\steamapps\common\assettocorsa\apps\python\)

Should looks like this:

assettocorsa/
└── apps/
    └── python/
        └── SpeedSensitive_Volume/
            ├── SoundVolumeView.exe
            ├── config.ini
            └── SpeedSensitive_Volume.py

2. Enable the app in the game settings:

• Settings → General → Python Apps → SpeedSensitive_Volume

🛠️ Configuration

You can edit config.ini:

[SpeedSensitiveVolume]
min_speed = 30 ; Volume starts increasing above this speed (km/h)
max_speed = 250 ; Full volume at this speed
min_volume = 20 ; Minimum volume (0-100)
max_volume = 100 ; Maximum volume (0-100)
scan_delay = 500 ; Refresh interval in milliseconds, do not change (can significatly increase CPU usage)

or configure in in-game menu

🧮 Algorithms

1. Linear Interpolation

volume = min_vol + (speed - min_speed)/(max_speed - min_speed) * (max_vol - min_vol)

• 🟢 Simple proportional adjustment
• 🔴 Sudden changes at speed thresholds

2. Exponential Scaling

volume = min_vol + (speed² / max_speed²) * (max_vol - min_vol)

• 🟢 Gradual increase at low speeds
• 🔴 Rapid increase at higher speeds

3. Logarithmic Scaling

volume = min_vol + log(speed+1)/log(max_speed+1) * (max_vol - min_vol)

• 🟢 Smooth transition across range
• 🔴 Requires speed > 0

4. Sigmoid Curve

volume = min_vol + (max_vol - min_vol) / (1 + exp(-(speed - min_speed)/(max_speed - min_speed) - 0.5))

• 🟢 Most natural sound transition
• 🔴 Complex calculation

To switch algorithms, modify the calculate_volume() function in the code

🖥️ GUI Overview

1. Music App Detection: Shows currently detected players
2. Real-time Indicators: Speed/volume progress bars
3. Configuration Menu:
   • Set speed/volume thresholds
   • Save/reset preferences
   • Enable/disable plugin

❓ FAQ

Q: My music app isn't detected
A: 1. Click "Scan music apps"
2. Add your app name to music_apps list in code

Q: Volume isn't changing

• Verify SoundVolumeView.exe location
• Run AC as Administrator
• Check app name spelling (case-sensitive)

Q: Best algorithm for city driving?
We recommend Exponential for smooth volume transitions in stop-and-go traffic
