The ASIO resolution , i.e. the audio bitrate, should always match the project settings in
the audio software that you are using. For example, if you work primarily with 24-bit audio
files (or want to record at 24 bits), select the same rate here. For best results, the ASIO
bitrate should match the bitrate configured for the hardware (USB page). If the
ASIO
Resolution does not match the hardware resolution, the sound quality can be improved
by selecting the “use dithering” option.
Dithering reduces undesired distortions, which can be caused by reducing resolution, for
example from 24 bit to 16 bit. While the signal-to-noise ratio (S/NR) is reduced by
dithering, the signal sounds better due to the decrease in distortion than it would without
the use of this method.
System Performance lets you adjust the ASIO latency in the input and output to the
speed of your computer system. The smaller the latency is, the greater the load on your
system, which you may be able to hear very clearly, for example, as sound drops during
playback. A middle setting should function reliably on all systems with ~1GHz processors.
Application Priority. The operating system processes all tasks (also called threads)
sequentially, while individual applications can be given different processing priority.
Normally, the priority here should be set to “Above Normal”. This ensures that the audio
thread is prioritized for latency-optimized use. Some audio applications additionally couple
the priority of the graphics board with the audio priority. If this is the case, it may be better
to lower the application priority in order to reduce crackling noises.
