Asio; Digicheck Windows - RME Audio ADI-2 Pro User Manual

25.5 ASIO

Start the ASIO software and select ASIO MADIface USB as the audio I/O device or the audio
driver.
The sample rate is set by the ASIO application. The buffer size (latency) is set in the RME Set-
tings dialog.
The number of available channels depends on the current Class Compliant mode: 2 channels
I/O when set to Stereo, 6 in / 8 out when set to Multi-channel. See chapter 14.1.3. Note: chang-
ing the CC-Mode requires to temporarily disconnect the ADI-2 Pro from the computer.
The ASIO 2.2 driver supports sample rates up to 768 kHz in PCM format. DSD record/playback
uses DoP within ASIO as transfer format. ASIO Direct Monitoring (ADM) is not supported.

26. DIGICheck Windows

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 5.82 operates as multi-client ASIO host, therefore can
be used in parallel to any software, with both inputs and outputs (!). The following is a short
summary of the currently available functions:
• Level Meter. High precision 24-bit resolution, 2/8 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.
• Spectral Analyser. World wide unique 10-, 20- or 30-band display in analog bandpass filter
technology. 192 kHz-capable!
• Vector Audio Scope. World wide unique Goniometer showing the typical afterglow of a
oscilloscope-tube. Includes Correlation meter and level meter.
• 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.
• Global Record. Long-term recording of all channels at lowest system load at up to 768 kHz.
• Completely multi-client. Open as many measurement windows as you like, on any chan-
nels and inputs or outputs!
