Time Delay Spectrometry, "TDS", is the most widely used TEF Program. TDS is now available as a Windows based application which runs in all of the current Windows programs - 95, 98, Me, 2000, NT and XP. Based on modern 32 bit code, it is easy to use and combines modern Windows functions with a look and feel that is still recognizable to current TEF users.

Fine-tune your capabilities

A long list of measurement capabilities means you can use Sound Lab TDS software to analyze a room and solve many acoustic problems. With Sound Lab TDS, you can identify and treat reflections, measure the frequency response of any given reflection, and perform equalizations by using the frequency response.

Sound Lab TDS simplifies aligning clusters and setting delay lines-both easily accomplished through data gained by the TEF. Comprehensive room analysis capabilities include measurements for reverberation, which can be obtained even in the presence of high ambient noise. Sound Lab TDS can also calculate speech intelligibility including %ALCONS, RASTI and STI. Other displays include the Nyquist (phase versus magnitude) and a 100-curve 3D waterfall. The ability to output pink noise, white noise and sine wave signals is included, eliminating the need to carry extra equipment.

New functions include a Pass/Fail Mode, an auto polarity test, easily modified user tests for standardized tests, and modern graphics support. Additionally, as a Windows based program it is possible to have multiple measurements tiled on the screen, and to move between them on a live basis.
