True - "beat frequency" between two very
close tones
may be much lower frequency than the tones themselves.
However, these lower frequencies would be recorded if you
are using live sources. Your room mic(s) should pick these
up and they would be recorded at 48KHz.
Jan, thanks. "Beat frequency" gives me a trail.
