but when i try to decode with:

Fortran runtime error: Substring out of bounds: lower bound (-1) of
'infile' is less than one
Hi Oliver,
the file name of the .WAV file is important, it is used to reflect the
time in the decoded message prints. Name the .WAV file according to this
pattern YYMMDD_hhmmss.WAV . You can use nonsensical patterns for a test
like 000000_000000.wav .
