Maybe that was not what you WANTED to do, but that is what you did. You
used atempo, the name is quite clear, it changes the tempo. And if you
do not trust the name, trust the documentation: "Adjust audio tempo.".

Compare to what was suggested to you:

>> Yes, this is possible with a combination of asetrate, atempo and
>> aresample filters.

You need to start paying attention.
