Japa's 'flat' response setting seems to approximate a Fletcher-Munson curve (see wikipedia). 'Prop' gives a flat response to a pink noise source (just route japa back to itself using qjackctl's connections window). I'm certain there are use cases for Jaaa's linear frequency axis, but I have never felt the need for it.
