十二平均律でのMIDIノート番号の対応表
・音名表記：ノート番号0をC-1とするものと
C-2とするものの二系列がある
・周波数：ノート番号69を440Hzとした場合
・cent (a)：ノート番号0を0centとした場合
・cent (b)：ノート番号69を0centとした場合
cent値の計算式
■比率をcent値で表わす
例） 9/8をcentで表わすと？
1200*LOG(9/8,2)=2003.9100
■cent値を比率で表わす
例） 100centを比率で表わすと？
POWER(2,100/1200)=1.0595
■440Hzが0の場合のcent値に対応する周波数
| 周波数＝440*POWER(2,cent値/1200) |
例） 100cent先の周波数は？
440*POWER(2,100/1200)=466.1638
・POWER(a,指数）は数値aのべき乗を返す関数
・LOG(b,底）は数値bの対数を返す関数
|
