Electroacoustics Toolbox 3.4 [k'd]

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.

Built-in Tools:

Dual FFT Analyzer (TF/IR analyzer)
FFT Analyzer
Meter Bridge
Octave Analyzer (RTA)
Oscilloscope
Signal Generator
Sound Level Meter
Spectrogram
X/Y Plotter

Additional 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 (Leq), time-weighted (Lp), and percentile-exceeded (Lx) sound levels
And more

Electroacoustics Toolbox is a project-based application, which allows you to configure and save project files. Projects may contain one or more tools available in the toolbox, along with any captured data associated with those tools. Electroacoustics Toolbox allows for the creation of an arbitrary number of tools of a certain type, or tools of different types. For example, a project may contain an oscilloscope, two FFT analyzers, and two signal generators. The oscilloscope and FFT analyzers may each simultaneously analyze multiple input channels of a single device. However, there is no requirement that all tools must work with the same device. The Toolbox also offers advanced capabilities for configuring input and output device parameters and assigning labels, units, and transducer sensitivities to individual input and output channels.

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
Whole device and individual channel sensitivity (level) 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
AppleScript support for measurement automation and remote control
