I'm going to guess that you have a sample of middle C (midi value 60) recorded at 22000hz.

C one octave up should be double the pitch (22000 x 2).

Therefore C# (one note above middle C) should be 22000 + (22000/12).
Therefore:
D = 22000 + 2x(22000/12)
E = 22000 + 3x(22000/12)
F = 22000 + 4x(22000/12)
etc

Any use? Worth trying anyway.
