Sound acceleration

[Baine]

Can anyone tell me what the difference in performance is between full sound acceleration, regular acceleration and no acceleration.
I sort of understand video acceleration _ good acceleration means better video performance. But what does sound acceleration do? Is there such thing as sound performance (and why don't we have gaming geeks everywhere worried about their sound rate, or whatever the sound equivelent is of frame rates).
I have noticed that my game performs better in regular  acceleration than in full. I don't get as many hesitations and sudden short stops. So, naturally, I'm wondering if I'd be even better off if I just turned acceleration off completely.
Can anyone explain the mysteries of sound hardware?
(P.S. _ I have probably the lowest cost and worst performing onboard sound chip in my system now. One reason I haven't upgraded to some nifty high-priced soundboard is my total ignorance of sound performance issues (that and, well, I'm just a cheap bastage).

Hnmmm..good question.  I ve asked it before and got completely
contradictivbe answer.
 Answer #1.  Sound acceleration uses your sound card in order
                     to relieve the CPU of sound burdon, thus your
                     performance improves, as far as frame rate goes,
                     when u increase your sound accelleration.  
                     
Answer#2.    Sound acceleration is like a perk.  The more u use,
                     the more resources are diverted to sound from
                    the CPU so your performance, as far as frame rate,
                   suffers.

Answer#3.  Sound has no effect on frame rate.


My tests indicate, no significant changes in frame rate with
  sound acceleration maxed out, as compared to min'd out.
I run mine at one notch below max, just cause that seems to be
the consensus.
  However, I am convinced that, sound can cripple frame rate.
For example, I am attacking a b17 form that is 1000 ft over the
vh, the 17s drop bombs as I am geting ready to open fire, the
bombs hit, explode, my frame rate drops off to grammas slideshow just as the massive esplosions start to rattle
and frame rate back to normal as they stop.
  Now, I have custom sounds.  Particularly, my bomb explosions
are awsome jaw rattlers at close range, and very real sounding at  a distance.  It is 279kb's, so I have deduced that this is
the problem.  If you have custom sounds and experiecne
bad frame rate during busy sound activitity, chk the size of
your sound files.
