Dear all,
I have five chimes. I've worked out the frequencies (using Audacity) of the
5 strongest partials of each chime. I now want to be able to work out how
to change the octaves of the various partials? My original intention was to
find the nearest midinote and just use those but after listening to the
results I would much prefer to keep the original ratio's whilst being able
to alter the 'inversions'.
Here's the list that I have already:
BT1
912Hz
2434Hz
4575Hz
7175Hz
11584Hz
BT2
1081Hz
2861Hz
5339Hz
8325Hz
15209Hz
BT3
1211Hz
3196Hz
5935Hz
9199Hz
15206Hz
BT4
1347Hz
3553Hz
6569Hz
10128Hz
18139Hz
BT5
1812Hz
4699Hz
8525Hz
13264Hz
15469Hz
Is there one piece of mathematrical wizardy that can sort this in Pd?
Cheers,
Jbz
