DartDisk User Guide

Playback Summary Screen

After closing the playback parameter screen, DartDisk displays a summary of the playback

parameters, showing the duration, sample rate, number of channels and source file name.

Playback will begin when the user clicks OK.

6. Acquisition and Playback Progress Screens

During acquistion and playback, DartDisk displays a progress screen containing:

• Numerical readout of elapsed acquisition time

• Numerical readout of current signal headroom

• Graphical bar display of elapsed acquisition time

• Graphical bar display of current headroom

Click Stop to halt the acquisition or playback before it completes. If acquisition is halted in

this way, sound data recorded up to that point is saved.

The meter also provides a summary display of total I/O time and total headroom when

acquistion or playback has completed. See the figures.

During simultaneous acquisition/playback, only the acquisition progress screen is displayed.

Elapsed Time Display

The meter shows elapsed acquisition or playback time graphically via a real-time linear bar

display and numerical readout. See the figures.

Headroom Display

The meter shows peak signal level graphically via a real-time linear bar display, similar to an

LED-based VU meter on a recording console. See the figures.
