17. DIGICheck: Analysis, Test and Measurements using the DIGI96 series

 

 
The DIGI96 series from RME is accompanied by a world wide unique software tool: DIGICheck, 
the incredible utility for test, measure and analysis of the digital audio data stream. 
 
DIGICheck is based on functions of our well-known DAM-1, the 

D

igital 

A

udio 

M

onitor. This 

device uses a built-in DSP for its calculations. Therefore DIGICheck is not able to realize all the 
functions of the DAM-1. Additionally, the DAM-1 works perfectly in the background while DIGI-
Check will cause a certain CPU load. 
 
DIGICheck also includes test routines from our research lab and our production site. Thus you 
are able for the first time to run a detailed function and performance test with your own audio 
card in your own computer, like it isn't possible with any other test tool. 
 
Although the DIGICheck software is fairly self-explanatory, it still includes a comprehensive 
online help. A detailed description of all functions and the technical background is also avai-
lable in HTML format (digich.htm, in the 

\techinfo

 directory on the RME Drivers CD or from our 

website). The following is a short summary of the available functions: 
 

• 

Level Meter

. High precision 24-bit resolution, 2/8 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 

• 

Channel Status Display

. Shows the channel status information contained in the digital 

audio data stream. Sample rate measurement 

• 

Bit Statistics

. Shows the true resolution of audio signals as well as errors and DC offset 

• 

Performance Test

. Measurement of the PCI-bus data transfer 

• 

Memory Test

. Tests the on board SRAM and the entire data path in the PC 

 
To install DIGICheck, go to the 

\DIGICheck

 directory on the RME Drivers CD and run 

se-

tup.exe

. Follow the instructions prompted on the screen. 

 

 

18. TECH INFO 

 
RME provides more information on the TECH INFO pages in the web (http://www.rme-
audio.com/techinfo/index.htm), and in the directory 

\rmeaudio.web\techinfo 

on the RME 

Driver CD. Here are some examples of available
