Logic and TDM - mixer resolution?

As far as I know, Pro Tools has a 48bit internal resolution, but Logic "only" 24bit.
Is the Logic mixer resolution also 48bit if I use it with a HD system?

G5 Dual 1,8, Mac OS X (10.4.8), 2 GB RAM ; Logic Pro 7.1.1 ; 2x UAD-1 ; RME FF800

Hi,

your information is not correct: ProTools (DAE) comes with a 48 Bit fixed point resolution, that partly truncates down to 24 Bit (fixed point again).

Logic is using a 32 Bit floating point audio engine, this is a different beast.

If you are using Logic with TDM: Now Logic is using the DAE too, with the same resolution as ProTools.

This is very quick and dirty information, you should investigate more by yourself into the differences between native and TDM (DAE) based audio and mixing engines.

Logic has a 32bit floating point resulution...? That's really new to me.

Are you sure, because when I got some Samplitude Files (which operates with an internal 32bit floating point resolution) I couldn't open them in Logic...

Hi,
you are confusing the resolution of a audio/mixing engine with the resolution of audio files.

Logic is mixing/processing with a 32 Bit floating point resolution.

Logic will not accept 32 Bit floating point audio files, only 24 or 16 Bit pcm audio files.

Logic is writing 32 Bit floating audio files internally when freezing.
