Personally, being a mere programmer and not any sort of audio geek, I don't understand why 0dB doesn't mean `dead silence'. I mean, that's what decibels are, right, a unit of sound intensity? So how can you have a negative sound intensity? -10dB reads to me like -10K on an absolute temperature scale would (and, yes, I know that -10K really does have a meaning, but it's a rather obscure one that doesn't relate to *thermodynamic* temperature, i.e. to what most people understand as `temperature'). I'm an extreme geek compared to pretty much everyone else I know off-net. I don't think I know *anyone* who wouldn't be confused by a negative volume. (It confused me enough that I hunted through the source to fix the bug, saw that it was intentional, and left it alone, shaking my head over the apparent bizarreness of this scale.) -- `The main high-level difference between Emacs and (say) UNIX, Windows, or BeOS... is that Emacs boots quicker.' --- PdSReceived on 2006-11-28 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
