20. HDSP Software

20.1 DIGICheck 4.0

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. DIGICheck 4.0 operates as multi-client ASIO host, and can

therefore be used in parallel to any software, be it MME, ASIO or GSIF, both inputs and even

outputs (!).

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, RMS level measurement, over-detection, phase correlation

measurement, 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.

• 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!

• 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.

• Totalyser. Spectral Analyser and Vector Audio Scope as one window function.

• Channel Status Display. Detailled analyzis and display of SPDIF and AES/EBU Channel

Status data.

• Completely Multi-client. Open as many measurement windows as you like, on any

channels and inputs or outputs!

To install DIGICheck, go to the \DIGICheck directory on the RME Driver CD and run setup.exe.

Follow the instructions prompted on the screen.

20.2 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 F3, 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.
