Like the HE-AAC V2/eAAC+ .m4a Profile uses Parametric Stereo by default, is PS also used, or something like it, within the HDC Codec of HD Radio?
It is known, HDC, to be based, partially, on the HE-AAC V1/AAC+ standard, but did it borrow that stereo trick, or something like it, for "Parametric Stereo"?
If so, does it help or harm sound quality, in a general sense?
Is the Stereo generally pretty convincing for normal listening enviornments (not ABX, normal)?
