SIGNAL and Real-Time Spectrogram (RTS) together provide real-time spectrographic display, signal editing, graphical display, advanced mathematical analysis, and sound modeling, synthesis, and playback of acoustic and vibration signals. Both programs are compatible with notebook computers.

Event Detector performs automatic event detection, converting an entire data tape into edited sound files or measured sound parameters. Event Analyzer performs automatic event analysis, calculating a number of sound parameters on all events in a data set and displaying summary histograms.

CBDisk, DartDisk, DTDisk, NIDisk, and WaveDisk perform direct-to-disk recording and playback, supporting analog I/O boards by Measurement Computing, Data Translation, National Instruments, and Sound Blaster compatibles. These programs can transform an entire data tape or live recording into a continuous sound file, or play back an entire digitized sound file.

Engineering Design was founded in 1980 to address problems in instrumentation and measurement, physical acoustics, and digital signal analysis. Company projects have included:

an 8-channel system for real-time detection of vocalizations from free-ranging elephants, and post-detection discrimination of vocalizations from noise

a two-channel ultrasonic system with direct-to-disk recording and playback, programmable attenuation, and total playback bandwidth of 1 MHz, for binaural stimulus presentation to bats

a multi-channel telemetry-based system for the acoustic tracking of bowhead whales, fielded for five years in the Alaskan arctic

a real-time ultrasonic target simulator providing variable echo delay and frequency shift, for studying Doppler-shift compensation in bats

a system for digitizing, CD-archiving, and quality-monitoring a library of 27,000 animal sounds

a 64-channel data acquisition and control system for 150-ton dynamic load testing of concrete structural models

a data acquisition and analysis system for measurement of ground-borne transmission loss in subway train vibrations

a low-noise (-127 dBV), high-gain (100 dB) differential microphone and preamplifier system for recording drosophila (fruit fly) wing acoustics

low-noise, high-precision electronic instrumentation for studio recording, field measurement, and laboratory experiments

Since 1984, Engineering Design has been the developer of the SIGNAL family of sound analysis software presented in this website. Application areas include sound and vibration measurement, sound modeling and synthesis, animal behavior, perceptual cognition, human auditory testing, and neurophysiological experimentation.

The principal and founder of Engineering Design is Mr. Kim Beeman, who brings 30 years of experience in instrumentation and measurement, digital signal analysis, software design, acoustical modeling, and analog circuit design.

SIGNAL sound analysis software is used at over 180 acoustic and bioacoustic research laboratories worldwide. Representative list of users.
