AUDIO KONTROL 1 – 75
USB Buffersize
and
Audio Buffersize
: These parameters are grayed out unless User
Defined Settings is selected instead of a Preset. Note that the Audio buffer
must always be at least twice as large as the USB buffer. Together the para-
meters define the system‘s latency, i.e. the time that passes from when a audio
signal is sent into the AUDIO KONTROL 1 hardware, manipulated digitally by
the computer and sent back to the hardware‘s outputs. Note that the USB
Buffersize parameter has a very strong effect on the CPU usage of the system.
The resulting CPU usage differs greatly between different computers, so it
makes sense to try out several USB settings. The USB Buffersize also has a
direct impact on the audio buffer, as the audio buffer must be at least twice
the USB latency.
Sample Rate
: Choose a sample rate that is compatible with your music applica-
tion. Higher sample rates use more CPU load, but have the potential to offer
higher fidelity.
Bit Resolution
: Choose the preferred bit resolution. A greater number of bits
deliver better dynamic range, but audio data recorded at higher resolutions
requires more memory for storage.
We recommend trying the first three latency presets first. If you have dropouts with
the preset “minimal latency”, try the “low latency” or “standard latency” settings.
The higher you set the audio buffer; the lower is the probability of audio dropouts.
The presets should be sufficient for most use cases. Please activate the User
Defined Settings only if you know what the USB Buffersize and Audio Buffersize
parameters are doing.
There are also two status fields along the bottom that show whether the
AUDIO KONTROL 1 hardware is ready and connected.
