Re: [PD] fader gain
hi derek
as Dafydd mentioned it, i use also a 'squared' scale. it is somehow in
the middle of the both extremes 'linear' and 'logarithmic'. linear is a
pain, when trying to adjust the volume in the low level area, whereas
the 'logarithmic' scale is too accurate in that area.
i'd say 'mathematically' correct is, what makes sense for your ears,
since all scales are 'mathematically' correct, but different. i
remember, that miller pucket posted once, that he uses {0-1}^4 (square
of a square).

[*~] (multiplied by sound from channel)
I know that this is the mathematically correct way to do decibels to
RMS, but it doesn't sound right. The bottom 2/3rds of the slider are
almost silent, then the sound comes in very loud at the top. What other
kind of setup are people using to control gain?

Re: [PD] fader gain
Hi Roman and Dafydd,
squared scale seems to work for what I'm using it for right now. Thanks
for the suggestion. If it still needs some tuning, maybe I'll try the
squared-square.
squarely yours,

Re: [PD] fader gain
Hi Derek Probably not the best solution, but to my ears, it sounds good to scale the input to 0-1 and then square it. cheers dafydd On 2/18/07, Derek Holzer [EMAIL PROTECTED] wrote: I've been using the following to control the output volume of a channel from my MIDI faders: [ctlin 7 1] (in from faderbox) | [* 0.787402] (scale 0-127 to 0-100) | [dbtorms] | [pack 0 50] | [*~] (multiplied by sound from channel) I know that this is the mathematically correct way to do decibels to RMS, but it doesn't sound right.

I want to point interested people to the great iem abstraction [fadtorms] and [fadtodb], in the cvs abstractions.
