Audio latency in arcade machines can ruin the gaming experience, making actions feel out of sync with sound effects. To minimize this issue, consider the following effective solutions:

1. Upgrade Audio Hardware: Use high-quality sound cards or DACs (Digital-to-Analog Converters) designed for low latency. Built-in audio chips often introduce delays.

2. Optimize Software Settings: Adjust buffer sizes in audio drivers or operating systems. Smaller buffers reduce latency but require more processing power.

3. Use ASIO or WASAPI Drivers: These drivers bypass unnecessary OS processing, significantly cutting down audio delay.

4. Close Background Applications: Running apps can hog CPU resources, increasing latency. Prioritize the arcade machine’s performance.

5. Check Game Code: Poorly optimized game audio code can cause delays. Ensure sound triggers are tied directly to game events.

6. Monitor System Performance: Overheating or outdated hardware may contribute to latency. Regular maintenance ensures smooth operation.

By combining hardware upgrades, software tweaks, and system optimizations, you can achieve near-instant audio response, enhancing gameplay immersion.
