Subject: software for pitch analysis

Hi,

does anybody have a suggestion for Software for the following tasks:

2. Pitch (Hz) to Cent calculator

-----------------------------

In base o this procedure it may make the Program.

1) Divide the given Hz by the Hz of the ocassional tonic, ( Let's say

440 ).

2) Make the LOG (10) of the result.

3) Multiply by 3986.3138. This result is the absolute Cents.

4a) If the result is major than 1200 rest 1200, and so on until the

result gives a quantity smaller than 1200 and major than 0. For this

variant 4a this is the Octaved final result.

4b) If the result is smaller than 0, add 1200, and so on until the

result gives a quantity major than 0. For this variant 4b this is the

Octaved final result.
