Logic Pro 9 32 Bit? 64 ? Options

[zam]

Hello ,
I ve just installed the upgrade from logic pro 8 to logic pro 9 , and in the same time i ve upgraded my OSX to snow leopard .
I thought that now logic will be in 32 bit , but when i load sample in 32 bit , nothing ??
When i go in the preference / audio and try to set the resolution ( i ve live ableton and the 32 bit work fine) , only 24 bit can be activated .
My question is , it is normal to have this system set like this , on my screen when i start the soft , it display logic pro 9.0.1 ( 32 bit) , so the soft start in 32 bit , how can be sure that the soft is in 32 bit , and if i want to increase to 64 bit , what is the operation to do.
Thanks a lot , in advance for your answer

You have undersoot dsomething wrong. 32 or 64 bit software depends on Operating system (32 bit OS or 64 bit OS) and this depends of You rmachine CPU. Most computers are 32 bit.
SO most probably Your Mac (and thus your sogtware) is 32 bit (means - built for running on computer with 32 bit CPU)
This has nothing to do with AUDIO BIT DEPTH that you are talking about.
Audio bit depth describes the number of bits of information recorded for each sample. Bit depth directly corresponds to the resolution of each sample in a set of digital audio data.CD quality audio, is 16 bits, and DVD-Audio 24-bit. Most studios record with 24 bit anf for CD they downsample it to 16 bit 44.100kHz

There is no point to use 32 bit audio. First - you have to downsample it to 24 or 16 anyway. Unless you have a 32-bit audio interface (and software), then you will not actually be recording nor playing at that rate. Most audio interaces for semi-prusers don't have 32 bit hardware ! 24 bits cover more than enough dynamic range than we can make use of and most audio interfaces do not have a low enough noise floor to push that to its full potential. recording at 32 bit would have no advantage over 24 bit.

Logic does npt suppert 32 bit audio import or export (nor does the Pro-Tools !) because there is no actual point for that. Just convert your files to 24 bit is what I can Suggest !
