One to 12 octaves can be measured and displayed.
1/1-, 1/3-, and 1/12-octave true center frequencies related by the
formula: f(i+1)/f(i) = 2^(1/n); n=1, 3, or 12; where 1000 Hz is the
reference for 1/1, 1/3 octave, and 1000*2^(1/24) Hz is the reference
for 1/12 octave. The marker returns the ANSI standard preferred
frequencies.
