Re: Is this lossless or lossy?

frequency analysis isn't really indicative of anything related to lossy data compression.

Room acoustics, mics, recording system (or transmission system, if recording a broadcast" can all show HF roll off. It is not, by itself, indicative of lossy data compression.

There are MP3 encoder settings that don't roll off much, if at all. Still chunks of data missing.

A good spectrum analyzer is the only good way to be sure if something has been run through lossy data compression, like MP3, ATRAC, etc.
