19. 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 0.64 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.
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 Fireface hardware.
• Vector Audio Scope. World wide unique Goniometer showing the typical afterglow of a
oscilloscope-tube. Includes Correlation meter and level meter.
• Surround Audio Scope. Professional Surround Level Meter with extended correlation
analysis, ITU weighting and ITU summing 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.
• Completely multi-client. Open as many measurement windows as you like, on any chan-
nels and inputs or outputs!

The newest information can always be found on our website www.rme-audio.com, section Sup-
port, Macintosh OS.
Playback works, but record doesn't:
• Check that there is a valid signal at the input.
• Check whether the Hammerfall DSP has been selected as recording device in the audio
application.
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 3FC5).
• Has Hammerfall DSP been selected as current playback device in the audio application?
The Multiface II fails after a few minutes
• The Multiface II requires a HDSP PCI revision 1.9 or higher. Older HDSP PCI cards do not
deliver enough current for the new Multiface II.
