Performance as seen below under Windows XP Home as seen above.
In addition, default sample rate selection under the driver properties is very important on
Windows Vista and Windows 7 otherwise sample rate variance or "Error opening sound device"
may occur, if your sound device driver (aside from USB port devices which are set to 48kHz
default) provides for selection of 48k, select it as the default format to prevent sample rate
conversion from taking place that will cause distortion artifacts even between say 48kHz and
44.1kHz. In Windows 7 the selection required as seen below is 2 channel, 16 bit, 48000Hz.
Should there be any reason to run an additional program using the sound device during the use
of this software, it too must use a 48kHz sample rate.
In Windows 7 and later share mode streams run in low-latency mode. The audio engine runs in
pull mode with a significant reduction in latency. This is very useful for communication
applications that require low audio stream latency for faster streaming.
