it just turned out to work very simply and intuitively when using midi-dB (i prefer to refer to pd's dB as such) with quite everything (this is: human perception, 16bit audio and MIDI)
For those not using MIDI (which I believe is the case of most PD users), midi-dB is not that intuitive... And I don't see any reference about midi-dB in Miller's book. I can believe that midi-dB is handy and make sense, but I used MIDI and I don't understand your explanation (and the conversion pseudo code).
If 128 values are used to control a 0-100 dB range, it means that the midi-dB resolution is 0.78 dB. For 16 bits audio, the range is 0-96 dB, so the midi-dB resolution is 0.75. For 24 bits audio, the range is 0-144 dB, so the midi-dB resolution is 1.125 dB. Is that correct? -- Marc
