Your reasoning is excellent, as any beat tones produced in the audible range could be recorded on a CD. However, where the beat tones come from is another matter.Some researchers discovered that the presence of the ultrasonic components was not audible if the ultrasonics and the audible signal were produced by different speakers. It seems that the intermodulation distortion produced by the interaction of of the audible signal and the ultrasonic signal was audible. However, when the intermodulation distortion was removed by using separate speakers, the test subjects could not disprove the null hypothesis in the DBTs.
Reference: Ashikara Kaoru and Kiryu Shogo, "Detection threshold for tones above 22 kHz," Audio Engineering Society Convention Paper 5401, presented at the 110th Convention, 2001 May 12-15, Amsterdam, The Netherlands.
