[PD] what happens when you send signals between 0..1 instead -1..1 to dac?

[Lucas Cordiviola]

I think the DAC/audiobackend/soundcard will accept those values "As is".

The Amp and the Speaker will just work on "one half" of their normal 
area. (50% of its audio loudness).

It shouldn't hurt the amp or the speaker as long as you don't try to 
pump up the volume. You might break the speaker if you increase too much 
the volume. (it will sound soft but you are pushing it too much to one 
of its extremes).
