Software Description

Electroacoustics Toolbox is a modularized, multi-channel dynamic signal analyzer and data acquisition platform. Electroacoustics Toolbox 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.


  • Multi-channel Dual FFT Analyzer for transfer function, impulse response, correlation, time delay, SNR, and other measurements of electrical, acoustical, and electroacoustic systems (filter circuits, listening rooms, loudspeakers, etc)
  • Multi-channel FFT Analyzer for real-time spectral analysis of input and output signals
  • Multi-channel Meter Bridge for a quick look at input signal levels
  • Multi-channel Oscilloscope for real-time viewing of input signal waveforms
  • Sound Level Meter for measuring instantaneous and time-averaged sound pressure levels
  • X/Y Plotter for measuring relative phase and creating Lissajous figures in real time
  • Signal Generator for real-time synthesis of various waveforms and test signals
  • Noise Dosimeter for convenient noise dose measurements
  • Hardware-accelerated OpenGL graphics for fast real-timeplotting
  • 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 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

New in v3.5

  • AppleScript support expanded
  • Room acoustics parameters are properly plotted across 1/3-octave bands in the Room Analyzer tool.
  • Radio buttons now work properly the IR source drawer of the Room Analyzer tool
  • Bugfix for issue that could prevent the "Try" buttons in the project window from opening a trial of the Noise Dosimeter or Room Analyzer tool.

New in v3.2

  • Two additional tools as in-app purchase add-ons - Room Acoustics Analyzer and a Noise Dosimeter
  • The new Room Analyzer tool employs the integrated impulse response method for calculating the acoustical parameters of a room.
  • The Noise Dosimeter tool measures daily noise dose according to standard methods, offering criterion sound levels of 80, 85, and 90 dB with 3, 4, and 5 dB exchange rates.
  • Various other bugfixes.

New in v3.0

  • Version 3 sports an improved user interface.
  • User preferences are available for individual tools.
  • Default audio device configurations, including channel labels, units, and sensitivity can be saved.
  • Virtual input channels can be added to audio input devices. Two-channel signal arithmetic (add, subtract, multiply) is now supported.
  • Arbitrary FFT lengths may be specified in FFT-based analysis tools.
  • Sound Level Meter and Octave Analyzer tools support percentile-exceeded sound levels.
  • Extended low-frequency support has been added to the Octave Analyzer.
  • The Spectrogram supports log frequency scales and real-time 3D spectrogram display.
  • Version 3 includes various other improvements over previous versions.
  • The Toolbox may now be purchased and maintained through the Mac App Store.

New in v2.1.9

  • Output channels of certain multi-channel audio interfaces, such as the MOTU UltraLite mk3, are properly enumerated.
  • Audio device channel gains on certain devices, such as the Wavelength Proton USB DAC, are properly restored when opening project files.
  • The reference delay value in the Dual FFT Analyzer tool's function table is presented with greater precision.
