A fresh 2 channel file, with a tone at 1 kHz on both channels. I also 
added the log files.
(some day i will have my own Raspi-based webserver, but there are still 
to many open projects already).
It looks like the effect is even more expressed at 1 kHz relative to 500 
Hz.
In the attachment you can see how it looks in SpecLab.
First the attachment size was 294 kB. The mail didn't arrive on the 
reflector. Now it is resized to 238 kB. Let's see if it comes through 
now :-)
