Electroacoustics ToolBox 2.1.8
Electroacoustics ToolBox 2.1.8 | Mac OS X | 7.1 MB
Electroacoustics Toolbox is a modularized, multi-channel dynamic signal analyzer and data acquisition platform for Mac. It brings powerful new tools to the Macintosh platform for multi-channel, audio-band data acquisition and real-time analysis of electrical, acoustical, and electroacoustic signals and systems. It enables precise measurements of acoustic quantities, such as equivalent and time-weighted sound levels, as well as acoustic and electroacoustic systems, such as listening rooms and loudspeakers. The software is designed to work with any Mac-compatible audio hardware and supports multiple channels of 8, 16, 24, or 32-bit data with sample rates as high as the hardware will support.
Measurements
Frequency response magnitude and phase
Impulse response
Auto and cross correlation
Time delay (latency)
Group delay
Signal-to-noise ratio (SNR)
Total harmonic distortion (THD, THD+N)
Coherence
Crest factor and rms, peak, and peak-to-peak signal levels
Signal mean, variance, and standard deviation values
Flat, A, and C-weighted equivalent and time-weighted sound levels
And many more!
Built-in Tools

Electroacoustics Toolbox Features
Hardware-accelerated OpenGL graphics for fast real-time plotting
Quartz-based graphics for high-resolution still images and prints
Advanced control over input and output devices
Device and individual channel calibration
Support for units, including Volts, Amps, Pascals, and Engineering Units
Saving complete configurations and data in project files
Exporting data to ascii text or MAT-files for easy import into other applications
Work with multiple independent audio devices simultaneously
No arbitrary limits on how many devices or channels are used, or on sample rates or signal formats–these are limited only by your hardware
Modular architecture for rapid development of additional tools, with the potential to allow third parties to develop custom plug-ins
AppleScript support for measurement automation and remote control
What's new:
Version 2.1.8 is a maintenance release that improves the stability of the application.
Dual FFT Analyzer: Added AppleScript access to the IR data window indices in the individual dual fft analyzer objects.
Dual FFT Analyzer: The windowed IR FFT length is now set somewhat arbitrarily to be as small as possible for the selected IR window. It is no longer constrained to be one of the user-selectable FFT lengths.
Dual FFT Analyzer: When the source or reference channel of a Dual FFT Analyzer channel gets set via AppleScript, the channel's sensitivity, units, and label values also get refreshed.
Dual FFT Analyzer: The time and time shift vectors are written with the correct (effective) sample period when data is exported to mat or text files.
System requirements:
Mac Platform: UB
OS version: 10.4
