DartDisk User Guide

6. Use SIGNAL to measure and analyze the sound events. Events can also be saved on disk

as individual sound files if desired.

7. SIGNAL can be programmed to perform many acoustic measurements automatically on

an entire group of sound files. See the programming chapters in the SIGNAL User

Guide

12. Using DartDisk with RTS

DartDISK can be used together with the Real-Time Spectrogram

(RTS) program to

record and visually review, measure, and edit extended acoustic data sequences up to hours in

length. The two programs work together as follows:

• DartDisk can digitize an entire data tape to a sound file, or perform direct-to-disk

recording, bypassing the tape entirely.

• RTS can rapidly page or scroll through the sound file on-screen, while measuring,

extracting, and storing sound parameters and sound segments directly from the screen.

Navigating a sound file on disk is much more efficient than playing, pausing, and

replaying from a tape player!

The RTS can scroll or page rapidly forward or backward through a sound file to search for

events interest. For example, this 30-second sample screen was scrolled in 3 seconds – a

review rate of 10 times real-time! The user can also page through the sound file in either

direction at 15 times real-time.
