Hi Rob, I just installed an evaluation license of the REAPER software and l=
ooked at it's 'Source properties...' command. I now believe that the incomp=
atibility of my recordings regarding the 'bext' chunk is caused by its unus=
ual location at the end of the file behind the 'data' chunk. I could change=
 that, but unfortunately this would cause a lot of re-programming work that=
 is usually also associated with some risk to introduce new bugs...

I believe that probably every other commercial field recorder places 'bext'=
 chunk before the data chunk, which should prevent such compatibility issue=
s.

It should be possible to write a software that allows to edit and rearrange=
 the individual chunks within a .wav file. I believe that the degree of dif=
ficulty involved in a such a software project would be mainly determined by=
 the experience of the programmer with the .wav file format and the RIFF ch=
unk concept. If he or she was already familiar with these things, then it s=
hould be quite easy and could probably be done within a few days.

Regards,
Raimund
