Rion DA-20PA1 Waveform Processing Software

Rion DA-20PA1 Waveform Processing Software

This simple but effective waveform processing software from Rion allows the user to carry out reanalysis of Rion DA-20 4 channel wav files. The DA-20PA1 automatically reads in the Rion wave file information from files recorded using the DA-20. DA-20PA1 can also be used with wav files recorded by the NA-28 and other Rion meters.

As well as carrying out FFT and 1/1, 1/3 octave band analysis of selected wav files, DA-20PA1 can also be used to obtain noise indices (such as LAmax, LAeq and LA90) and even 'Successive Statistics' (e.g. stats for specified successive periods within a recording) from the recorded wav file. When carrying out 1/1, 1/3 octave band analysis, the user can select to see the Statistics Panel, which will then allow the processing of environmental statistics on the 1/1 or 1/3 octave band data. For example, the user can obtain L90 or Lmax data in 1/3 octave bands.

  • Specific processed data can be exported and saved as a text file, ready to be opened into a spreadsheet.
  • Correctly opens Rion wav files automatically importing calibration settings and sensitivities
  • Replay the data via the computer's soundcard
  • Quickly pick out events (e.g. train pass bys), apply a work-zone and calculate results (e.g. 1/3 octave Lmax) for that event, then the next one...
  • Obtain 'Successive Stats' as if using a data logger to gather measurement indices for successive measurement periods (including indices for each octave or third octave band)
  • Apply noise frequency weightings to raw data
  • Apply time weightings to raw data
  • FFT Analysis (25 – 12800 lines)
  • 1/1, 1/3 Octave Band Analysis
  • Hi pass, lo pass and user-specified band-pass filters
  • First and second order differentiation and integration
  • Export processed data to a text file
  • Save selected portions of signals to new wav files
  • Graphs generated by DA-20 PA1 can be copied straight into reports
