Generating a Signal from Waterfall
This section shows how to generate a signal from a Waterfall file, which includes a series of successive spectra associated to several RPM calculation points.
Note: The processing used in Sound: Analysis and Specification assumes that for each RPM
point, the frequency lines are the same (for all RPM points: same number of frequencies, and
same order of frequencies). Then, Sound: Analysis and Specification generates sinusoidal
components whose frequency and level evolve according to the RPM. A linear interpolation of
the dB level value is made to create the data between the known RPM points.
Sound creation is made using a linear RPM profile, in an RPM range specified by the user.
To use any RPM evolution (not neccessarily a linear one) you can define a harmonics source in the Sound Composer application (see Creating a Track with a Harmonics Source).
To Create a Sound from Waterfall Calculation:
The sound is created in a temporal window.
Tip: Next is right-clicking the waveform to calculate the spectrum.
