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 
(for example in TotalMix). 

 

The 8 ADAT channels don’t seem to work 
 

• 

The optical output ADAT1 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.
