Multi-channel, audio-band data acquisition and real-time analysis of electrical, acoustical signals. The Faber Electroacoustics Toolbox (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. 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.After running the installer, ElectroacousticsToolbox.mpkg, double-click the Electroacoustics Toolbox icon to launch the program and you'll be on your way. Electroacoustics Toolbox's basic functions are designed to be very intuitive to use. Documentation can be accessed from the Help menu.You may want to have an audio input signal ready to really see what Electroacoustics Toolbox can do. Some options for input signals include an external microphone, an audio mixer output, CD player output, or if you have a Powerbook, you can use the built-in microphone. Alternatively, you can route output signals from the signal generator tool directly to any of the analyzer tools without the need for any external audio hardware.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 options for configuring input and output device parameters and assigning labels, units, and transducer sensitivities to individual input and output channels.
