Digital Display Demo
Illustrates the use of the Digital Display components for displaying audio and control signal levels. In this example, the
mono displays are used to measure the signal level of a pure tone from the Sine Wave Generator. Start the
DrawingBoard.You will observe that the signal level is constant, as expected for a continuous pure tone. Also, the Simple
Control Display is configured to display the instantantaneous value of the audio (via the Audio To Control conversion
block). As expected, this display fluctuates periodically between +/- 1 (corresponding to the sine wave of amplitude 1).
The stereo displays are used here to measure the signal level of a drum track. As expected, the indicated signal levels
fluctuate as the audio track evolves.
The displays are calibrated such that an amplitude of 1 corresponds to a dB value of 0. If the amplitude exceeds 1 (or the
dB level exceeds 0), digital clipping has occured. This sounds nasty and should generally be avoided by reducing the gain
somewhere on the DrawingBoard.
Refer to the " AudioLevelDisplayDemo.dwb" and the "DigitalClippingEducationalExample.dwb" for a discussion on how to
use WaveWarps Audio LED displays to prevent digital clipping.
