Sample rate conversion question

Only in arithmetic. It's really no easier to convert 88.2 kHz to 44.1
kHz as to convert 96 kHz, or 50 kHz or 163.4 kHz. You still have to
recalculate every sample. You can't get good results by simply taking
every other sample as some people infer.
You can, IF you do a lowpass at 22 KHz first. This is called "filtering
and decimating" and is sort of the crudest possible sample rate conversion.
Most actual realworld software, though, uses the same algorithm whether or
not you are dividing by an integral factor.
