16. DIGICheck
The DIGICheck software is a unique utility developed for testing, measuring and analysing
digital audio streams. Although this Windows software is fairly self-explanatory, it still includes
a comprehensive online help. DIGICheck 4.4 operates as multi-client ASIO host, therefore can
be used in parallel to any software, be it MME, ASIO or GSIF, with both inputs and outputs (!).
The following is a short summary of the currently available functions:
Level Meter. High precision 24-bit resolution, 2/8/18 channels. Application examples: Peak
level measurement, RMS level measurement, over-detection, phase correlation measure-
ment, dynamic range and signal-to-noise ratios, RMS to peak difference (loudness), long
term peak measurement, input check. Oversampling mode for levels higher than 0 dBFS.
Vertical and horizontal mode. Slow RMS and RLB weighting filter. Supports visualization
according to the K-system.
Hardware Level Meter for Input, Playback and Output. As above, received pre-calculated
directly from the HDSP system hardware with near zero CPU load.
Spectral Analyser. World wide unique 10-, 20- or 30-band display in analog bandpass-filter
technology. 192 kHz-capable!
Vector Audio Scope. World wide unique Goniometer showing the typical afterglow of an
oscilloscope-tube. Includes Correlation meter and level meter.
Totalyser. Spectral Analyser, Level Meter and Vector Audio Scope in a single window.
Bit Statistics & Noise. Shows the true resolution of audio signals as well as errors and DC
offset. Includes Signal to Noise measurement in dB and dBA, plus DC measurement.
Channel Status Display. Detailled analyzis and display of SPDIF and AES/EBU Channel
Status data.
Completely multi-client. Open as many measurement windows as you like, on any chan-
nels and inputs or outputs!
To install DIGICheck, go to the \DIGICheck directory on the RME Driver CD and run setup.exe.
Follow the instructions prompted on the screen.
DIGICheck is conctantly improved. The latest version is always found on our website

Latest Additions.
The input signal cannot be monitored in real-time
ASIO Direct Monitoring has not been enabled, and/or monitoring has been disabled globally.
The 8 ADAT channels don't seem to work
The optical output has been switched to SPDIF. The ADAT playback devices are still usable
by routing and mixing them in TotalMix to other outputs.
Low Latency ASIO operation under Windows 2000/XP on single CPU systems:
To use ASIO at lowest latencies under Windows 2000/XP even when only having one CPU,
the system performance has to be optimized for background tasks. Go to >Control Panel/
System/ Advanced/ Performance Options<. Change the default 'Applications' to 'Background
tasks'. The lowest usable latency will drop from 23 ms to around 3 ms.
