There are more factors than simple dynamic range
My thoughts exactly. The clue is in the name?: double _precision_. A
modular-ish synth plugin I am working on passes signals around
internally with double precision. A while ago I changed the whole
thing so it worked with 32 bit floats instead and I instantly felt a
loss of fidelity even though the AU outputs are obviously 32 bit
floats. Lots of people are starting to conduct tests like this and
many people report similar findings.
I don't think anyone has mentioned this yet and correct me if I'm
wrong but you can't do double precision computation with SSE/Altivec
which could be significant for certain plugins.
