[Openal] Filter problems

[Daniel PEACOCK]

Hi Andy,

I believe the equation is correct.  It seems to give sensible results when
plugging in different source and listener positions and velocities.  Are
you getting unexpected pitch shifts?

Page 15 of the OpenAL Programmer's Guide quotes the doppler equation as:

f' = f * (SS - DF*vls) / (SS - DF*vss)

Should this not be

f' = f * (SS - DF*vls) / (SS + DF*vss)

(ie. plus instead of minus in the divisor)? Or am I misreading the
equation?
