18. HDSP Software
18.1 DIGICheck
The DIGICheck software is a unique utility developed for testing, measuring and analysing
digital audio streams. Although the DIGICheck software is fairly self-explanatory, it still includes
a comprehensive online help. A detailed description of all functions is also available in HTML
format (digich.htm, in the \techinfo directory on the RME Driver CD or from our website). The
following is a short summary of the available functions:
Level Meter. High precision 24-bit resolution, 2/8/26 channels. Application examples: Peak
level
measurement,
measurement, dynamic range and signal-to-noise ratios, RMS to peak difference
(loudness), long term peak measurement, input check.
Bit Statistics. Shows the true resolution of audio signals as well as errors and DC offset.
Performance Test. Measures overall system performance (computer + HDSP)
Memory Test. Tests the Hammerfall hardware and the entire audio data path in the PC
To install DIGICheck, go to the \DIGICheck directory on the RME Driver CD and run setup.exe.
Follow the instructions prompted on the screen.
18.2 HDSP Meter Bridge
The Hammerfall DSP Meter Bridge is a unique, highly flexible and handy tool for level
metering. As opposed to DIGICheck, the HDSP Meter Bridge receives all level data directly
from the hardware. Thus the Meter Bridge can run in parallel to any other program. As Peak
and RMS calculations are performed directly in hardware, the CPU load caused is limited to the
graphics routines – and is near zero on todays computers.
Although the HDSP Meter Bridge is fairly self-explanatory, it still includes a comprehensive
online help. To start press F2 and F7, the most important hotkeys.
To install the HDSP Meter Bridge, go to the \HDSP Meter Bridge directory on the RME Driver
CD and run setup.exe. Follow the instructions prompted on the screen.
