Adjustable dynamic range/white point in spectrogram

[adventuretc]

Some microphones are good in sound quality, but insensitive.
The audio that I observe gets colors from the low end of the Color map and it would be nice to be able to use the whole color map.

Can you please make a setting for Spectrogram "upper limit" or "white point"?

If the "View Range Setting" would apply to the colors of the Spectrogram that would be great as well.

So you want to increase the contract of low-dB part right?

There are several possible options:

• There is a setting: "Spectrogram range" in preference, you can set it to 150dB to cover the low end. This actually decrease the contract a bit, but make the picture brighter so that it may help.
• Pick a color map that have higher contract at low end, e.g. Parula, Jet or Hot.
• Pick a sound source that have a higher gain, e.g. MIC, DEFAULT, different phone have different gain setting, you need to try this out.

If all these suggestions fail to meet you needs, the "View Range Setting" will be good place to implement it as you suggest :-)
