Recording a 32bit float file would mean there's no need to apply an additional dither process to convert to 24bit for file transfer and the mastering engineer could probably remove any clips (overloads) inadvertently incurred during mixing. The target for 32bit float files is really for transferring files to say a mastering engineer (for example). You have to remember that 32bit float has no more accuracy than 24bit fixed, it essentially just provides an exponent which means that it's almost impossible to clip. The "people" you have spoken to are misinformed, they will not achieve higher quality by converting to 32bit float. Who was the target audience for 32 bit recording and processing? I have spoken to a few people who have mentioned to me that they wish to import in the production audio and up convert the 24bit files to 32 bit WAv files so they can have better sound quality when they are cleaning up noisy dialogue with RX2 and other audio suite plugins. ProTools 32bit processing has been around for about a dozen years and is nothing new but apart from the potential benefit of almost unlimited headroom, doesn't offer much (if any) audio quality improvements over TDM fixed point. Situations where 32bit audio files would be an improvement over 24bit audio files are rare and unlikely to impact most audio post workflows. Ed - You seem to be confusing 32bit audio files with 32bit processing/mixing. On balance, there is not much difference, except you have to be careful to follow decent gain staging with TDM mixing. It's a bit more complicated with ProTools HD (TDM) though, because we are comparing 32bit float with the TDM mixer which is often using 48bit precision, 56bit summing and 24bit data paths! Additionally, fixed point doesn't have the problems with dither that 32bit float can have. Not really an interesting read as the article is comparing 32bit floating point with 16bit fixed point processing, no contest. The floating point path is much better than fixed point. He is talking about internal headroom, and yes you get more headroom.
