Post Processing Designed from the Ground Up with Ngara.

The Firefly software package designed by ARL is a data management/visualisation and audio waveform post-processing platform designed to operate seamlessly with the Ngara™ Noise Logger.

Firefly allows the user to view recorded statistical data (such as Leq, Lmax and Ln) over the entire period for which the logging occurred or as a daily view.

"... display a side-by-side comparison..."

Statistical data can also be re-processed with different frequency weightings or statistical intervals depending on the user's requirements. Firefly also allows the user to zoom in to regions of interest and display a side-by-side comparison of data from multiple Ngara™ loggers.

"...allows the Ngara™ system to function as a 1/1 and 1/3 octave analyser..."

Firefly also allows the Ngara™ system to function as a 1/1 and 1/3 octave analyser by extracting octave band data from the recorded high-resolution audio waveform files. Users can also view the octave analysis output while listening to the recorded audio and even output a section of the audio session as a compressed .mp3 file.

Octave data can be output with the following parameters:

  • Frequency Weighting: A, C and Z
  • Time Weighting: Fast and Slow
  • Customisable Filters: Low Pass, High Pass, Band Pass, Band Stop and All Pass
  • Percentile sound levels: Ln (1% to 99%, Max 8 values)
