They didn't specify bit depth either. I understand all of this reads like pointless pedantry, but a) it feels good indulging in it b) certain word combinations (such as "CD quality") have meanings backed by broad consensus, please use them responsibly so readers do not have to overexert their loose interpretation muscle. If they mean wide band, say wide band, noone will bat an eye.
