Additional software options for use with the TEF25 USB Dual-Channel Analyser

SLPPS60 - Sound Lab Post Processing Module
The post-processing module captures the raw data from a Time Delay Spectrometry (TDS) sweep, and allows the user to post-process directly from the impulse response.

This provides all the traditional advantages of Maximum Length Sequence analysis, but with the signal to noise advantages of TDS. It therefore offers the acoustician the best of both worlds, enabling a single measurement to be taken in the field, with the data being subsequently processed for different time spans; it allows changes to start point, stops on frequency parameters and checks of RT60 times. A thoroughly practical and powerful tool.

SLNLA60 - Sound Lab Noise Level Analysis Module
This software module enables a variety of noise-related analysis tasks to be managed quickly and efficiently. It allows analysis of environmental noise and statistical noise, for example, enabling detailed measurements to be carried out.

Annotation tags can be added to individual events, which can be labelled and stored for reference. The module's statistical display function can show a breakdown of Leq occurrences, and a pair of cursors can be placed on the display to focus on areas of special interest.

The module also enables fine time resolutions to be captured over very long periods, and Leq measurements at one-minute intervals over a 24-hour period are easily taken. With its totally flexible approach, this module represents an extremely comprehensive noise analysis resource.
