21. DIGICheck Mac
The DIGICheck software is a unique utility developed for testing, measuring and analysing digi-
tal audio streams. Although this Windows software is fairly self-explanatory, it still includes a
comprehensive online help. DIGICheck 0.65 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, 2/8/18 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 ac-
cording 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 Fireface hardware.
•
Vector Audio Scope . World wide unique Goniometer showing the typical afterglow of a
oscilloscope-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
analysis, 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 multi-client. Open as many measurement windows as you like, on any chan-
nels and inputs!

The newest information can always be found on our website

port, Macintosh OS.
Playback works, but record doesn’t:
•
Check that there is a valid signal at the input.
•
Check whether the HDSPe has been selected as recording device in the audio application.
•
Check whether the sample frequency set in the audio application (‘Recording properties’ or
similar) matches the input signal.
•
Check that cables/devices have not been connected in a closed loop. If so, set the system’s
clock mode to Master.
Crackle during record or playback:
•
Increase the number and size of buffers in the application.
•
Try different cables to rule out any defects here.
The card and drivers have been installed correctly, but playback does not work:
•
Is Hammerfall DSP listed in the System Profiler/PCI? (Vendor 10EE, Device ID 3FC6).
•
Has Hammerfall DSP been selected as current playback device in the audio application?
