16. DIGICheck
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 4.5 operates as multi-client ASIO host, therefore can be
used in parallel to any software, be it WDM, MME, ASIO or GSIF, with both inputs and outputs
(!). The following is a short summary of the currently available functions:
•
Level Meter . High precision 24-bit resolution, 2/10/28 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.
•
Hardware Level Meter for Input , Playback and Output . Reference Level Meter freely con-
figurable, causing near zero CPU load, because calculated from the Fireface hardware.
