22.3 Multi-interface Operation
The current driver supports up to three RME devices of the MADIface series. All units have to
be in sync, i.e. have to receive valid digital sync information. Under ASIO all devices are
presented as one ASIO device with all available channels as I/Os.
If one of the units is set to clock mode Master, all others have to be set to clock mode Slave,
and have to be synced from the master by feeding ADAT, AES or SPDIF. The clock modes of
all units have to be set up correctly in their Settings dialog.
22.4 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
Settings dialog.
The ASIO 2.2 driver supports sample rates up to 768 kHz in PCM format. DSD record/playback
is supported as DoP within ASIO as well as via ASIO native. ASIO Direct Monitoring (ADM) is
not supported.
23. DIGICheck Windows
The DIGICheck software is a unique utility developed for testing, measuring and analysing
digital audio streams. Although this Windows software is fairly self-explanatory, it still includes a
comprehensive online help. DIGICheck 5.92 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 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.
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.
• Completely multi-client. Open as many measurement windows as you like, on any
channels and inputs or outputs!
