Electroacoustics Toolbox 2.1.1

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

Electroacoustics Toolbox brings powerful tools to the Macintosh platform for multi-channel, audio-band data acquisition and real-time analysis of electrical, acoustical, and electroacoustic signals and systems. Electroacoustics Toolbox enables precision 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.

Electroacoustics Toolbox features:

• 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
• Fractional Octave Analyzer for octave and 1/3-octave spectral analysis
• Multi-channel Oscilloscope for real-time viewing of input signal waveforms
• Sound Level Meter for measuring instantaneous and time-averaged sound pressure levels
• Spectrogram analyzer with advanced 3D display options and cursors for pinpointing important data
• 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
• 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
• AppleScript support
