72% of all desktop computers run Windows software. Windows is great for many applications, office tasks, gaming, and other everyday activities. Unfortunately, it is not optimized for audio use.

Unlike specialized operating systems such as macOS or Linux, Windows isn't built from the core for real-time audio processing. This means that the Windows task scheduling mechanism, designed primarily for general computing tasks, doesn't prioritize real-time audio processing. As a result, audio-related tasks can face delays or interruptions from other system processes, resulting in audio dropouts and audio glitches, especially when using demanding applications like DAWs.

While using Windows for audio production, you may encounter challenges in achieving consistent and reliable audio performance. If you're using a USB audio interface and notice such problems, we suggest following the steps provided below to help mitigate this.

Non-Windows sources of error

Before blaming your operating system, it's essential to explore other potential causes of audio problems. We've compiled a checklist to help you troubleshoot common audio issues effectively.

  1. Audio device drivers 
    Make sure that the correct drivers for your audio device are installed and functioning correctly. Check for any reported issues with the drivers provided by the manufacturer. 
     
  2. Adequate RAM 
    Confirm that your computer has sufficient RAM to support the software you're using. Insufficient RAM can lead to performance issues, including audio dropouts. 
     
  3. Storage Space 
    Ensure that your computer has enough storage space for smooth operation. To avoid performance degradation, aim to keep at least 20% of your total storage capacity free.
     
  4. USB connections 
    Examine the USB cable, ports, and USB hubs connected to your audio device. Ensure they meet the device's specifications and are free from faults that could affect audio performance.
     
  5. Cloud storage
    Do not access files and projects directly from cloud storage services while working on audio tasks. Cloud access can introduce latency and performance issues.
     
  6. Idle applications
    Shut down any unnecessary applications or background processes that may consume system resources. This step can free up resources for smoother audio performance. 

Windows system adjustments

If all the above points comply, it is likely the reason for your trouble lies within the Windows operating system. Please try the following steps to improve the behavior: 

  1. Disable system sounds 

Search for "Control Panel" -> "Hardware and Sound" -> "Sound" -> "Sounds" tab -> "Sound Scheme menu" -> choose "No Sounds" -> "OK" 

Playback recording sounds menu

  1. High-performance power settings 

Search for "Power Options" -> "Create a power plan" -> "High Performance" -> Name your plan, for example, "Audio Optimized Plan" -> Set "Turn off the display" and "Put the computer to sleep" to "Never" -> "Create"

  1. Disable USB selective suspend 

Search for “Edit power plan” -> “Change advanced power settings” -> “USB settings” -> On battery / Plugged in “disable” -> “OK” 

Power options menu

  1. Adjust processor power management 

Select "Change Plan Settings" for your custom power plan -> Open "Advanced power settings" -> Expand "USB settings" -> Disable "USB Selective suspend" -> Expand "Processor power management" -> Set the minimum and maximum process state to 100.

  1. Processor schedule 

Search for "Advanced system settings" -> "Advanced" tab -> "Performance” -> “Settings…" -> "Advanced" tab -> activate "Background services" -> "Apply" -> “OK” 

Performance options menu

  1. Disable startup apps  

Search for "Task Manager" -> "More details" -> "Startup" tab -> select all apps that are not required for automatic launch -> "Disable"

  1. USB power management settings 

Search for "Device Manager" -> open dropdown menu of “Universal Serial Bus controllers” -> right-click all items -> "Properties" -> "Power Management" tab -> uncheck "Allow the computer to turn off this device to save power" -> “OK”

  1. Disable network cards 

Sometimes network cards cause audio issues, if the network card is not the cause of an issue it is advised to revert this action. Search for "Device Manager" -> open dropdown menu of “Network adapters” -> right-click items -> “disable”

  1. Disable “C States” 

To conserve energy, some CPUs have low-power modes called "C-states" or "C-modes" implemented. Disabling C-states in your computer's BIOS might resolve audio issues.  

This process varies depending on your PC's hardware, and we strongly advise getting in touch with the motherboard manufacturer for assistance. 

  1. Hard drive compression 

Locate your hard drive(s) intended to use for audio work -> Right-click "Properties" -> "General" tab -> uncheck both "Compress this drive to save disk space" and "Allow files on this drive to have contents indexed" -> "Apply" -> "OK"
