Octave Stretch
People generally feel that a note whose frequency is twice another notes
frequency is somehow "the same note" only higher. If you have a piano handy,
play the D note (between the pair of black notes) in each octave. The frequency
of each D note is about twice that of the lower D note.
But many people feel that the octave is not EXACTLY 2.0 times the lower
note. To many people, two notes whose ratios is slightly different than
2.0 sound more alike.
Important: please do NOT hit the "Print Stretch" button until the
instructions tell you to!
To Do:
-
Slide the fader all the way the left.

Hit the "Play Stretched Octave" button. Listen to the two notes.
-
Slide the fader all the way the right.
-
Hit the "Play Stretched Octave" button. Listen to the two notes.
-
Adjust the fader until the two notes sound like the same note an "octave"
apart.
-
Hit the "Print Stretch" button to see what your ears hear as an octave.
Note that there is no right or wrong answer but most people feel that a
5 to 10 cent stretch sounds best.
