Electroacoustics Toolbox 4+

This app, Electroacoustics Toolbox, is no longer recommended for purchase. It has been replaced by SignalScope X and SignalScope Pro 2022, which run on newer versions of macOS, iPadOS, and iOS.

Electroacoustics Toolbox is a modularized, multi-channel dynamic signal analyzer and data acquisition platform. 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 (Leq), time-weighted (Lp), and percentile-exceeded (Lx) sound levels
- And more!

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
- Room Analyzer tool for estimating room acoustics parameters from impulse response data (T20, T30, T60, EDT, Clarity, Definition, Center Time).
- Noise Dosimeter tool for measuring noise dose with various threshold and criterion levels, with 3, 4, and 5 dB exchange rates.

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.

Electroacoustics Toolbox Features
