Recording a Software's playback

In real world application, recording a software's output with another software will show the fol-

lowing problem: The record software tries to open the same playback channel as the playback

software (already active), or the playback one has already opened the input channel which

should be used by the record software.

This problem can easily be solved. First make sure that all rules for proper multi-client opera-

tion are met (not using the same record/playback channels in both programs). Then route the

playback signal via TotalMix to a hardware output in the range of the record software, and acti-

vate it via Ctrl-mouse for recording.

21. 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. DIGICheck 4.2 operates as multi-client ASIO host, and can

therefore be used in parallel to any software, be it WDM, 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 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.

• 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 chan-

nels 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.

Note: The dedicated Meter Bridge known from RME's HDSP series, a professional level display

nearly without CPU load, will be added soon to DIGICheck. It can then be used with the Fire-

face 800 too.
