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 Descriptionter

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
