DartDisk

provides direct-to-disk data acquisition and playback using the Dart PCMCIA

analog I/O card from Engineering Design. Program capabilities include:

• Recording and playback of 1 or 2 channels at up to 50 kHz sample rate

• 16-bit resolution on acquisition and playback

• Built-in anti-alias filter on acquisition and playback

• Programmable input gain up to 22.5 dB

• Recording and playback duration up to the capacity of the hard disk

• Records and plays sound data in either SIGNAL or Wave file format

• Runs under Windows 95/98/2000/XP

DartDisk supports the Dart PCMCIA card, but this card can be installed in a desktop using a

PCMCIA adapter. Sample applications include:

• Use with a notebook computer to perform continuous data acquisition in the field,

replacing an expensive digital recorder

• Use with a notebook computer to perform field playbacks

• Use with a desktop computer to provide an I/O workstation for streaming data

collection in the lab, for later analysis in SIGNAL or RTS

DartDisk can store acquired data in either SIGNAL or Wave file format. Both file types can

be read directly into SIGNAL or RTS for display and analysis. Applications for DartDisk

sound files within the SIGNAL family include:

• Review, measure, and edit sound data in the RTS

• Produce continuous spectrograms in SIGNAL

• Automatically analyze recorded files for sound events using the Event Detector

• Read file segments into SIGNAL for precision display and measurement
