You might view this article if you experience these problems:

• Pops, clicks, humming and distorted sounds when you record or playback audio.
• A delay between when you play your instrument/microphone/MIDI instrument and hearing the sound from your speakers/headphones (latency). 
• Your Windows machine runs slowly or keeps crashing.

Basic Tips

Free up space

Don’t let your computer’s boot drive get too full. Always make sure you leave more than 20% of your computer's main hard drive empty. To see how much storage has been used:

1. Click the Windows icon and type and select ‘Settings’
2. Select ‘System’ 
3. Select ‘Storage’ 

The bar will show how much storage has been used and is free. You can remove files you no longer need or move them to external/cloud storage.

You can also use the Disk Cleanup tool to remove temporary files and files or folders you no longer need. This can save you lots of space. The cleanup operation can take a few minutes to up to an hour, so only try this if you have time to spare. To use the Disk Cleanup tool: 

1. Click the Windows icon, type and select 'Disk Cleanup'.
2. Select your C: drive, check everything and click OK.
3. Go back to Disk Cleanup, select the C: drive again, click Clean up system files.
4. Select everything, click OK. This process may take a while, especially if you’ve never done this before, so don’t shut down or restart your computer during the cleanup operation. The window will disappear once it’s finished.

Use enough memory

If you are running large projects involving sample libraries and multiple plugins, we recommend your computer has at least 8GB of RAM.

Use a suitable USB cable for your Hardware

Make sure you use a short USB cable, either the one in the box with your interface or a cable shorter than 2 metres. Using longer USB cables with your interface can cause dropouts, glitches or stop your interface from working.

Ensure your interface has its own dedicated USB port

USB hubs are known to cause issues with audio devices. These issues can include noise, and connection problems. Therefore, we recommend your interface is connected directly to its own USB port.

Close all other background applications

When you run your DAW (Digital Audio Workstation), make sure you close applications you are not using, such as

• Music streaming apps (Spotify etc.)
• Web browsers (Chrome, Edge etc.)
• Office applications (Word, Excel etc.). 

This will free up power for your DAW, preventing your system from running slowly when multiple programs are trying to use the machine. 

Main Tips

Optimise Focusrite software and buffer size

Ensure you have the latest version of the Focusrite driver or control software installed. You can find the latest version for your device on our Downloads Page.

If you experience glitchy audio with your Focusrite interface, increase the buffer size and test the interface again. To do this, right-click on the Focusrite Notifier and select your device's settings. Increase the buffer size to 1024. If the performance improves, you can try a lower setting.

If you are unsure what buffer size is and how it affects performance, please see this article:

Sample Rate, Bit Depth & Buffer Size Explained

If you can’t see the Focusrite notifier in your taskbar:

1. Go to your taskbar (in the bottom right corner of your desktop). 
2. Click on the arrow facing up (^).
3. Locate the Focusrite notifier (presented as a small ‘F’).
4. Drag and drop the Focusrite Notifier into the main area of the taskbar.

NOTE: we strongly recommend disabling "Cortana" as this program can sometimes attempt to use the inputs on your audio interface at inopportune moments (e.g. when you're in the middle of a recording session).

Disable system sounds

1. Search in the start menu for Control Panel 
2. Select ‘Hardware and Sound’
