This plugin allows creating a series of pre-calculated Acoustic Photos/Movies for all frequencies within the selected interval. These photos or movies can be generated from a spectrum and from a spectrogram.
Narrow-band analysis, 1/3 octave analysis, spectrum, replay of sources and listening to points in the picture are features of this plugin.
A spectrum can be used to display the frequency spectra contained in a time function. A spectrogram enables the user to display the frequency spectrum of a single channel or the average frequency spectrum of multiple channels over time. Here, sound pressure level (SPL) is displayed in color codes.
NLS (non-linear spectral dissection after Dahl) is possible in the spectrum as well as in the spectrogram.
