Electroacoustics Toolbox 3.0 is out!

Electroacoustics Toolbox 3.0 for Mac OS 10.6 is now available for download on the new Mac App Store and at FaberAcoustical.com. Faber Acoustical has announced the release of Electroacoustics Toolbox 3.0. The latest release of Faber Acoustical’s flagship acoustical test and measurement toolset is now available for purchase in the Mac App Store and at FaberAcoustical.com. Version 3 of Faber Acoustical’s flagship product features an enhanced user interface, better control over audio device configurations, and more comprehensive user preferences. New functionality in the Toolbox includes the option to perform arithmetic operations, such as addition, subtraction, and multiplication, on two arbitrary input channels of an audio input device. Users can also specify arbitrary FFT lengths and view live spectrogram data in […]

Measuring Time Delay with Electroacoustics Toolbox

Measuring Time Delay in an Audio System Using Electroacoustics Toolbox Although Electroacoustics Toolbox is not limited to measuring audio systems, the measurement of audio systems is a common use that offers convenient ways to demonstrate the capabilities of the software. These examples can then be applied to other applications in which the Toolbox’s measurement capabilities may be considered useful. At times it is desirable to measure the delay of a signal through some component, or group of components, in an audio system. For example, when a digital signal processor (DSP) is employed in an audio system, to optimize or otherwise alter the listening experience, it may be desirable to measure the delay introduced by the DSP’s algorithms in the audio […]

Measuring Audio Unit Effect Plug-ins With Electroacoustics Toolbox

Measuring Audio Unit Effects Plug-ins Using Electroacoustics Toolbox, Soundflower, and AU Lab A valuable use of Electroacoustics Toolbox is measuring Audio Unit effects. Measuring Audio Units can be useful to developers of such plug-ins, or to anyone employing Audio Unit effects in their digital audio recording, editing, or reproduction system. This tutorial requires two free software packages in addition to the Toolbox: Soundflower and AU Lab. AU Lab is distributed with Tiger (Mac OS X, 10.4). Soundflower is a free system extension for Mac OS X, version 10.2 or later, that allows for convenient routing of audio signals between applications on the Mac. More information regarding Soundflower, as well as a download link may be found at cycling74.com. (Version 1.2 […]

Audio Interface Frequency Response Measurement with Electroacoustics Toolbox

This article was originally published in the forums for version 2 of Electroacoustics Toolbox. Please visit the following link for an updated tutorial for version 3. Frequency Response Measurement with Electroacoustics Toolbox 3 Measuring the Frequency Response of Your Audio Device One of the most powerful tools in Electroacoustics Toolbox is the Dual FFT Analyzer, which is capable of measuring system transfer functions and even indicating the quality of the measurement. This tutorial focuses on using the Dual FFT Analyzer to measure the frequency response of the audio device that you use to measure other systems and devices. If you want to measure the frequency response, or impulse response, of a listening room for example, that measurement will be affected […]
