Audio Processing Section

The Audio Processing section in the Audio Settings page of the Control Panel.

The Audio Processing section sets parameters for the analog-to-digital / digital-to-analog con-

version done by your audio interface. It has two menus:

• Sample Rate: Choose a sample rate that is compatible with your music application and

best suited to your computing power. A higher sample rate improves the audio quality, but

also causes higher CPU load. By default, the sample rate is set to 44100 Hz (CD quality).

If you want to use multiple software clients simultaneously with the device, keep in mind

they'll also have to share the same sample rate.

• Process Buffer : Lower the buffer size value for a quicker response time from your com-

puter to audio software actions.

When converting audio information to digital and vice versa, the audio driver needs to store

the data in buffer packages (audio buffers), which are then sent to and processed by the

CPU. The higher the buffer size, the longer it takes for a signal to finally arrive at the out-

put as audio. You might experience this as a delay between the time you hit a key on your

computer or controller and when you actually hear the sound. This delay is called latency.

A rule of thumb: lowering buffer size results in lower latency. However, there are more fac-

tors to latency than buffer size alone (e.g., CPU speed and RAM size). Start off with a high-

er buffer size setting and gradually decrease the value until you find the perfect balance

between audio quality and system performance. If you experience crackling at the audio

output, the chosen buffer size is very likely too low for your computer’s CPU to handle con-

sidering that a lower buffer size causes higher CPU load.

• USB Buffer: Changing the USB Buffer size (Process Buffer) affects the ASIO and the

WDM driver. Supported USB Buffers (in ms) are: 1, 2, 3, 4. Default USB Buffer: 3ms
