Proper dB read from the Amplifier Beginner Question

Indeed to put x in dB it's just 10*Log10(x)

There is no Log10 stream component but you can use a code component with the following:

streamin in; streamout out; out = log10(in);

What about from float output of Knob thats controlling the amp.

You can directly connect Float data to any of stream connectors.

Since a sample is a representation of a voltage, shouldn't it be 20*log10(x)?

That's what I thought too, 20*log10(x). Hrmmm!
