StealthPedal

CS
2.9 Windows Control Panel
In order to open the Control Panel (figure 2.5), click on the “StealthPedal
icon” located in the Windows tray, (please check the Windows taskbar, usu-
ally located at the bottom next to the clock).
Control Panel description:
ASIO Buffer Size: sets the StealthPedal’s input/output latency. The smaller
the buffer size value is, the faster the response.
IMPORTANT: too small a buffer size may introduce audio pop and click
noises or CPU overload. Reliable operation highly depends on the perfor-
mance and configuration of your system. Also, if there is an open audio
application that is using the StealthPedal’s ASIO driver, you will not be
able to change the buffer size value from the StealthPedal’s Control Panel.
In this case, you will need to either:
a) close the application before you modify the buffer size or
b) open the StealthPedal Control Panel from within the Audio Application
settings by clicking on the button that is usually named “Control Panel”.
ASIO Processing Time: adjusts the processing time of the internal ASIO
driver. The higher the value, the more reliable the system will be in
terms of audio quality at the expense of a slightly higher latency. Lower
values will further reduce latency but will increase the ASIO driver CPU
load, this could create audio pops and clicks at extreme settings.
ASIO Driver: there are two options available: ‘Open’ and ‘Steaming’.
Open: ASIO driver is opened by an ASIO host application. This means that
the driver cannot be accessed by another ASIO host at the same time.
Streaming: ASIO driver is streaming audio data between ASIO host
and hardware device. This means that USB bandwidth has been
allocated for the input and output audio streams.
Input Gain Boost: when checked boosts the StealthPedal input sensitivity by
12dB. Depending on the instrument you’re using set this option so that you
get an input signal that is as high as possible without overloading or clipping.
Output Volume: controls the audio output volume of StealthPedal.
