The Faber Electroacoustics Toolbox (FEaT) is a modularized, multi-channel dynamic signal analyzer and data acquisition platform for Mac.

FEaT 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)
• 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 and time-weighted sound levels
• And many more!

Built-in Tools

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

Plug-in Tools (licensed separately)

• Noise Dosimeter

FEaT 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.  FEaT allows for the creation of any 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.

FEaT also offers advanced capabilities for configuring input and output device parameters and assigning labels, units, and transducer sensitivities to individual input and output channels.
