TerraSonde Analysts Firmware
Oct 7, 2003 12:00 PM, Editors
The Analysts Firmware module brings the power of three measurements within the reach of any Audio Toolbox owner: Multi-Band RT60, STIpa and TDA. The module installs easily on the Audio Toolbox and includes all of the measurements from TerraSonde's Contractors firmware module, as well.
TerraSonde offers a custom multiband RT60 measurement as the first new tool in the suite. The user can read eight different RT60 times from a single burst of wide-band pink noise. The results are provided in real time and can be saved to memory for plotting and reporting.
STIpa is a new speech-intelligibility standard developed to more closely correlate with the Speech Intelligibility Index. STI-PA, which stands for STI for Public Address, is a measurement in which seven different frequency bands are analyzed simultaneously within a specific pink-noise waveform. The result is expressed in a "score" that is indicative of the amount of speech intelligibility from that position. The process takes place in real time on the Toolbox.
TDA is TerraSonde's version of time-delay spectrometry. Used in conjunction with a special version TerraLink, users will be able to create and print 3-D waterfall graphs of reverb decay vs. frequency, as well as be able to visually see room modes and uneven decay responses.
The Analysts firmware module includes the above tools, as well as the other audio tests and measurements found in TerraSonde's Contractors firmware. It also includes a special version of TerraLink, TerraSonde's external software application.
