Host Forum: Sonic Visualiser / Spectrogram contrast
« on: December 10, 2009, 21:48:59 »
Hello everyone,
I am the creator of the website www.vlf.it, and I am dealing with radio signals of natural origin and seismic precursors radio. I just discovered Sonic Visualizer and I am very impressed: it is a good tool for the analysis and study of the signals.
But I am not able to do one thing: as I do to increase the contrast in the spectrogram? The color palette is distributed over the entire dynamic of the signal (90 dB if the file is 16-bit). As you set to ensure that the color range is spread for example on only 30 dB? I found the volume control but that moves the palette up or down, it does not change the extension.
Thanks, Renato
