Equalize the intensity of sounds for the same chosen volume.

Hello.
Thanks for this great app.
I noticed that the noises listened to for the same volume setting do not seem to be on the same power level. Is this the case? If so is this normal? For example the fuzz, gray, gray 2, brown and blue sounds seem lower to me than the white or pink sounds.
It seems to me that if possible, it would be desirable to equalize the intensity of all sounds to the intensity of the white or pink sound.
Cordially.
