Digicheck - RME Audio HDSPe MADI User Manual

12. 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 com-
prehensive online help. DIGICheck 5.93 operates as multi-client ASIO host, therefore can be
used in parallel to any software, be it WDM or ASIO, with both inputs and outputs (!). The follow-
ing is a short summary of the currently available functions:
 Level Meter. High precision 24-bit resolution, 2/8/64 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 ac-
cording to the K-system.
 Hardware Level Meter for Input, Playback and Output. Reference Level Meters freely con-
figurable, causing near zero CPU load, because calculated from the HDSPe hardware.
 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.
 Surround Audio Scope. Professional Surround Level Meter with extended correlation analy-
sis, ITU weighting and ITU summing meter.
 ITU1770/EBU R128 Meter. For standardized loudness measurements.

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. Detailed analysis and display of SPDIF and AES/EBU Channel
Status data.
 Global Record. Long-term recording of all channels at lowest system load.
 Completely multi-client. Open as many measurement windows as you like, on any chan-
nels and inputs or outputs!
DIGICheck is free but works only with RME interfaces. It is constantly improved and updated.
