Logic Pro 8 16 bit files in a 24 bit world - Myth?

[mikekiraly1]

Ok, I am about to expose my weakness of believing everything I hear - but I am curious enough to know if it's based in truth....

I once heard that if there were various audio files in a project of differing bit rates (some at 16, some at 24) that any plug-ins that had to process both types of files (say a bus or the master) would lose some of it's processing quality in order to accommodate the lower bit rate file - something about it needing to process at the lowest common bit rate.

I am a pretty smart guy, and I have never read or seen any evidence to support this, but I still can't help but wondering. Can someone tell me if this has any basis in fact?

All audio in Logic (using the CoreAudio or DTDM driver) is processed using a 32 Bit Float engine. It doesn't matter what the source specs of the audio are.

I thought so -it sounded so crazy, but I've heard crazier 🙂
