16. DIGICheck NG Mac
The DIGICheck software is a unique utility developed for testing, measuring and analysing digital
audio streams. Although this Mac software is fairly self-explanatory, it still includes a comprehen-
sive online help. DIGICheck 0.89 operates in parallel to any software, showing all input data. The
following is a short summary of the currently available functions:

Level Meter . High precision 24-bit resolution, 2/8/128 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 . Reference Level Meter freely con-
figurable, causing near zero CPU load, because calculated from the MADIface hardware.

Vector Audio Scope . World wide unique Goniometer showing the typical afterglow of a oscil-
loscope-tube. Includes Correlation meter and level meter.

Spectral Analyser. World wide unique 10-, 20- or 30-band display in analog bandpass filter
technology. 192 kHz-capable!

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.

Completely multiclient. Open as many measurement windows as you like, on any channels
and inputs or outputs!
