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 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 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?
