Now offering acoustical measurements using
state-of-the-art TEF-20 analyzer. 

New! MLS, PEQ, PET, PLR, RTA, SLX, and TDS and are now available as Windows based programs.

Maximum Length Sequence "MLS", Precision Equalization "PEQ", Polar Energy Time Curves "PET", Polar "PLR", Real Time Analysis "RTA", Sound Lab Xtras "SLX" and Time Delay Spectrometry "TDS", are the most widely used TEF Programs. They are now available as Windows based applications which run in all of the current Windows programs - 95, 98, Me, 2000, NT and XP. Based on modern 32 bit code, they are easy to use and combine modern Windows functions with a look and feel that is still recognizable to current TEF users.

TEF and INTELLIGIBILITY - The TEF20 analyzer was put through it's paces at an Intelligibility Workshop. Download the article. 419K. This article is provided through the courtesy of Syn-Aud-Con.

Be sure to visit our TEF accessory page. We have added new items that compliment the TEF measurement system.

The TEF20 is a dedicated instrument designed to perform Time, Energy and Frequency (TEF®) measurements using the science of Time Delay Spectrometry (TDS).

The power of the TEF platform lies in its ability to join specialized software and the TEF20 analyzer with your computer to form a complete measurement system.

The TEF20 features a powerful DSP device with the speed and power to execute millions of instructions per second enabling it to accurately process complex acoustical data.

Sound contractors, consultants and engineers rely on the TEF when they design, install and verify sound systems and solve problems associated with various aspects of room evaluation.

Optional software packages perform such functions as real time analysis, precision equalization, noise level analysis to name a few.

An invaluable tool, the TEF analyzer enables the sound professional to see and measure existing acoustical problems while evaluating each change as it is made. When it comes to system design, verification and validation, nothing comes close to a TEF.
