wave file shape problem

When I drop the wave file, the sound comes out in sausage form, even though it is normal db.
The sound will be smaller, but if I want to get my shape back to normal, I’ll have to use the mousewheel to reduce it to about 40 db.
Does anyone know how to solve it?

Use the manual, or even the forum search for „waveform zoom (slider)“. The one top right

thank you!
