Direct-to-disk recording & playback !

CBDisk(tm), DartDisk(tm), DTDisk(tm), NIDisk(tm), and WaveDisk(tm) are a family of inexpensive programs capable of performing high-speed, unlimited-duration, direct-to-disk data acquisition and playback. These programs turn your computer into an easy-to-use digital recorder or playback instrument. They can be used for recording or playback in lab or field, and to digitize entire data tapes for automated analysis using the Event Detector.

CBDisk, DartDisk, DTDisk, NIDisk, and WaveDisk support every I/O card manufactured by Computer Boards, Communication Automation (Dart card), Data Translation, National Instruments, and Sound Blaster-compatible manufacturers, respectively. These programs read and write SIGNAL or Wave format sound files, for compatibility with other sound recording and analysis software.

These programs do not require SIGNAL in order to operate. They can be installed on any Windows 95/98/2000/XP computer for stand-alone data acquisition or playback.

Principal features follow. Note: maximum number of channels and sample rate depend on the I/O card.

• Record up to 8 simultaneous input channels
• Record at up to 1.25 MHz sample rate
• Play back 1 or 2 output channels
• Play back at up to 500 kHz sample rate
• Support for programmable input gains
• Record and play sound files in either SIGNAL or Wave file format
• File duration may be as larage as the hard disk

Sample applications include:

• Use with a notebook computer to perform continuous data acquisition in the field, replacing an expensive digital or ultrasonic tape 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

Applications for recorded sound files include:

• Digitize entire data tapes for automated analysis using the Event Detector
• Read file segments into SIGNAL for precision display and measurement
• Produce continuous hardcopy spectrograms in SIGNAL

• Flexible control of recording parameters: Programs display an acquisition parameter screen which allows the user to specify acquisition duration, sample rate, input gain, number of channels, output filename prefix, output file type and optional overwrite of pre-existing files.

• Real-time recording progress: These programs report the duration of sound acquired so far and display a progress bar. Click Stop to halt the acquisition before it completes, and the sound data recorded up to that point will be saved.
