Re: An introduction to compressed audio with Vorbis
...consistently zero
(not -32768). A "pure" tone is produced by samples whose values conform
to a sine function -- a "sine wave". The frequency of the sine wave
(i.e., how quickly the numbers go up and down) determines the frequency
of the sound, which we perceive as pitch. The amplititude of the sine
wave -- how far the wave deviates from zero -- determines how loud it is.
A sine wave that goes from, say, -1000 to +1000 is much quieter than
one that goes from -5000 to +5000. A sine wave that goes from -32767
to +32767 is as loud as you can get.
My explanation may leave a bit to be...
