KiRAT - Kiel Real-time Application Toolkit

With regard to the sound card, the installation of a sound card driver is particularly important. To do this, simply google the device name and install a suitable driver.

With regard to the sound card, the installation of a sound card driver is particularly important. To do this, simply google the device name and install a suitable driver. The buffer size and sample rate can then be adjusted to the values set in KiRAT. It is also important to select the number of WDM devices, as this number defines the number of inputs and outputs.

If you cannot hear anything over the headphones, the first step is to observe the output signal in the GUI. Use the plotter in the lower "Visualizations" part of the GUI and select KiRAT Main Signals -> Output Signals. Check the checkboxes of the signals and select the output signals. If you cannot see a signal, choose IO Manager -> Signal Mapping Output in the upper "Algorithmic Structures" part of the GUI. Try to find the right channel of your soundcard device until you get an output signal in the plotter. You may also have a look in the TotalMix console to find the right channel. If you see a signal but do not hear anything, check if you see level changes in Total Mix in a specific channel that matches your audio input and still cannot hear anything, try checking your hardware by switching to other devices or restarting all hardware devices. You can also check to see if Windows is using the correct devices for audio input and output. If not, try switching to the correct ones (your devices should be audio devices!). If this is not possible, the reason could be the USB settings of your sound card: Check if the WDM Devices parameter is set correctly, the number should match the number of inputs/outputs of your sound card.
