Pick a "reference level" for the toolbox #10

Closed achabotl closed 10 years ago

achabotl commented 10 years ago

Should pick a "reference level" for signals. For example, should a signal with an RMS value of 1 correspond to 0 dB, 100 dB, or something else?

We could use a physical standard too, where an RMS of 20e-6 corresponds to 0 dB, i.e.

level = 20 * log10(rms / 20e-6)
