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

* Group delay
* Signal-to-noise ratio (SNR)
* Coherence
* Many others


Built-in Tools

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


Plug-in Tools

* Noise Dosimeter


New Tools in Version 1.1:

Octave Analyzer

* Features whole and 1/3-octave real-time spectral analysis using
digital Butterworth bandpass filters, as recommended by ANSI Standards
* Supports calibrated sound level measurements in whole and 1/3-octave
bands, including Lp, Lp_max, Lp_peak, and Leq
* Flat, A, and C frequency weighting
* Fast and Slow time weighting
* Supports non-acoustic signals with units other than Pascals
* Captures current spectrum for later review

Spectrogram Analyzer

* Hardware-accelerated graphics with OpenGL
* 3D data visualization with colorful surface and mesh plots
* Zoom and Pan controls for enhanced viewing of spectral data
* Trackball-style rotation of the data in 3D display mode
* Cursors for pinpointing spectral data as a function of time and
frequency
* Cursor lines follow the data surface in time and frequency in the 3D
view
* Multiple color schemes for visualizing the spectral data
* Captures current spectrogram data for later review or export


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.
