Thanks for your info.

I know baudline but I'm a (happy) windows user. I also know SpectrumLab because Wolf (DL4YHF developer) is my friend (I am also one of the software debugger). I was looking for an alternative for the analysis of wave files. SpectrumLab is the best software for direct processing, but it has some gaps on the recording files post processing.

Bye, Renato

Host Forum: Sonic Visualiser / Spectrogram contrast

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
