can anyone tell me, when recording or playing back paf files in paris, is there any kind of compression scheme going on, or is it strictly a linear affair of digital audio, with absolutely no compression going on at all?
I ask this because, when I use an alesis m20 to record or playback, there is no compression whatsoever used- and you can HEAR it. it sounds like open reel to reel, to MY ears, only even better! Paris comes very close to sounding like open reel, but not quite- and I'm wondering if any kind of compression scheme or algorithm might at least in part explain it--- or, like the m20, does paris record and playback TOTALLY in linear fashion?--- VERY useful information to me to know- and I'll very much appreciate anyone who can give me a correct and knowledgeable answer. thanks in advance.

I once did a test. I recorded something at 24 bits. I then made a copy and truncated it to 16 bits. I flipped the polarity of the 16 bit version and mixed it back into the original 24 bit file.
I knew that the audio that was left over would be the extra information captured at 24 bit but not present at 16 bit.
I played back the file and heard...absolutely nothing.
I zoomed right in, and I could see something down at -90 dB. It was hiss.
When one considers the dynamic range of the best mics barely approach 90 dB, it makes sense that the additional bits in a 24 bit file are capturing mostly hiss from the mic.
Of course, headroom is good. But, it's not like 16 bit sounds bad.
All the best,
Mike
