Dynamic visualization replay software
A post treatment dynamic visualization of the data is possible with the dedicated software: DaViS. It performs acoustics analysis in replay mode from .wav file of your DORI underwater acoustic recorder.
DaViS displays :
- the spectrogram,
- the temporal evolution of Sound Pressure Level (SPL),
- the Power Spectral Density
- the third octave band levels.
In addition, this software allows an audio listening.
Key specifications of our underwater acoustic data display software DaViS
✓ Gain and sensitivity of hydrophone are automatically filled
✓ Acoustic levels directly in dB re 1µPa
✓ Modular display and user friendly
✓ Free of charge – included with recorders

Area of interest selection
The selection of a time interval of interest can be made by selecting directly in the spectrogram. Next, another section appears with final acoustic information about this selected interval: a zoom of the spectrogram, power spectral density, third octave band level and SPL values are shown while real time values are still displayed on the main graphs.
