But as you'll see, it's not for float, or at least float in the sense of
continuous, parameters. It's for parameters that have descrete choices,
with unit type kAudioUnitParameterUnit_Indexed. What you are looking for
is not here yet but will come with the next update, as Bill mentioned a
couple days ago, with a new kAudioUnitProperty_ParameterValueName
property.

Of course, you could also make the parameter's unit type be
kAudioUnitParameterUnit_Decibels and provide the parameter's value range
in the actual dB range (or something close enough, since probably won't
want to make the minimum literally -infinity). But maybe that doesn't
work well for your particular case, I don't know...
