precision (based on PITCH_SPEED_PRECISION). Note that these are

all constant expressions, which will be evaluated at compile time,

2020-10-26 16:38:22 +00:00

That's just to get the precision right.

2020-10-26 16:38:22 +00:00

I calculated these values, starting from 50, as
|
2009-07-11 16:46:19 +00:00
|
|
|
|
|
|
|
x(n) = 50 * 2^(n/12)
|
|
|
|
|
|
|
|
All that math in each entry simply converts the float constant
|
|
|
|
to an integer equal to PITCH_SPEED_PRECISION times the float value,
|
2009-07-12 17:14:01 +00:00

|
with as little precision loss as possible (i.e. correctly rounding
|
|
|
|
the last digit).
