MS-DMT Guide v1.04

Aside from non modem related processes causing CPU loading and latency issues, the PC sound
device sample clock accuracy, first program capture of the sound device issue under some OS’s
and sample clock stability come into question as does sound device noise floor, deterministic
phase jitter and other parameters. In addition, as we are not talking a Turn-Key system
approach, there are also configuration management challenges as to providing and maintaining
the best possible operating system configuration dedicated to the task.
Thus to achieve the best results with this software the MS-DMT tool must be the only
application that is making use of the PC Sound Device, the MS-Windows environment must be
tamed down to mitigate if not completely eliminate the demands on the computer system
resources and the operating system latency issues that affect real-time audio streaming and RS-
232 signaling timing, all of which some users may find a bit challenging to achieve!
