-- Free REal TIme Audio Analyzer (version2)
pronounced \fʁe.ti.ja\ ("frétilla", which means wagged in french) also accept \fʁe.s.ia\ , which means nothing I think ;-).
Fretiaa2.0 is a software to make real time audio /acoustical analyses.
- Oscillogram
- ...to come Spectrum
- ...to come Spectrogram (Time-Frequency representation)
- ...to come Fractional-Octave-Band Spectrum (e.g. 1-Octave, 1/3-Octave, ...) [according to the NF EN 61260:1995 Standard]
- VU-Meter (in dBFS)
- ...to come dB-Meter: A-, C- or Z- Weighting, and Fast, Slow or Impulsional time integration [according to the NF EN 61672-2:2002 standard]
- MultiMeter: maximum, minimum, average and RMS (Root-Mean-Square) values
All charts include exploration tools (zoom, auto zoom, selection of Region of Interest), axes ranges and single value viewing.
- ...to come: Hear the signal
- ...to come: Open/Save the signal as audio file (.wav file)
- ...to come: RealTime HighPass-filter (Fc=20Hz)
- ...to come: Single Shot Trigger: stop recording when the signal exceeds teh trigger level
- Signal amplitude adjustement according to the input acquisition set-up (mic, preAmp, ADC input gain (in dB, dBV or dBu)
- ...to come: Choose between Volt and Pascal representation unit
- Select zone using rectangle used to compute Oscillogram, Spectrum, Spectrogram, Octave-spectrum, Multimeter, dB-Meter, or VU-Meter
- Export data from charts in csv format
- Export graphs as pictures
