Mathematically, no loss.
Implementation, possible loss.
Reversing the audio is relatively straight-forward, and
is usually implemented correctly in most DAWs.
If your DAW has an "audio file compare" function, you
can run a quick experiment to validate that the reversal
process is accurate:
- select a file
- make a copy of the file
- reverse the copy and then reverse it again (reverse 2x)
- save the "reverse 2x" copy
- compare the original file and the "reverse 2x" copy
The two files should be absolutely identical.
I just ran this test on my Cube-Tec Audiocube (64-bit
version of Wavelab 6.10) with a short 7-minute audio file,
and the entire process above took less than 4 minutes.
The two files were indeed absolutely identical.
