NIDisk User Guide

5. Playback

Performing Playback

To perform a playback, select I/O | Play on the NIDisk menu. NIDisk displays the Playback

parameter screen, which allows the user to configure the playback. NIDisk then displays the

Playback summary screen, which summarizes playback parameters and allows the user to

initiate the playback.

Playback Parameter Screen

The Playback parameters screen allows the user to specify the file to be played, triggering

mode and optional alarm sounds. Other parameters such as duration, sample rate and number

of channels are predetermined by the sound file. The playback file may be a 1- or 2-channel

SIGNAL or Wave file. Wave files must be stored in uncompressed 16-bit coding (0 offset,

±32768 range), which is the "PCM" or "type 1" standard

Wave file format.

Filename specifies the name of the file to be played, including file extension (e.g., myfile.1

or myfile.wav). If the filename does not include a full path (drive letter and directory), files

are played from the directory containing NIDisk. Embedded spaces are allowed in the

filename.

NIDisk accepts SIGNAL integer-format files and Wave files, but not SIGNAL floating-point

format files. SIGNAL files are strongly recommended.
