this depends on how you store the data: fixed-point formats will clip
your data to -1..+1
for floating point soundfiles, i guess it depends on the actual format
you are using (but i am no expert here)

i just tried to store a table with a maximum sample value of 2.9199 with
the soundfile-object as 4byte floating-point (-nextstep -bytes 4), and
lo and behold! the file restores to the exact values (maximum 2.9199)

at least the arrays look the same, i haven't done any scientific
