About UE Systems

UE Spectralyser

The UE Spectralyzer program provides the user with the tools for performing basic spectral analysis on audible sound images. The program displays spectral (FFT), time series, dual (FFT and time series), waterfall, and parametric information on 5 main display windows.


  • 44.1KHz Max Sampling Rate Supported (hardware dependant Averaging: Vector, Peak Hold, RMS
  • Frequency Span: (0 to 1/2 of selected sampling rate)
  • Weighing: Exponential, Linear
  • Single Channel Operation
  • FFT Windowing
  • Spectral Overlays
  • Modes: Realtime, Record & Playback
  • Narrowband FFT sizes through 32,768 points
  • Cursors: Frequency & dB, Harmonic & Alarm
  • Displays: Spectrum & Time Series
  • Alarm Cursor: Low Frequency, High Frequency & dB Setpoints
  • Frequency Markers


A spectrum analyzer creates a visual image of sound. It displays the amplitude and frequency components of a recorded sound in a screen that looks similar to that of an oscilloscope (an oscilloscope shows time and amplitude). The frequency limit is set by the parameters of the computer sound card. This is related to the sampling rate capabilities of the sound card. The sampling rate establishes how many times a second the analogue input signal is sampled by the sound card. 

The software user can perform program functions by selecting options from the programs main tool bar. The user can control particular aspects of the display windows using program controls. The program controls appear on the scale legend, cursor controls, graph pallet, overlay pallet, and plot legend.  Additionally the user can control the operation of the spectral analysis by using the control buttons (REC, RUN, STOP & RWD).
