In the nokia smart messaging Document the sclae of one note is from 5 (440Hz) to 8, but in the rtttl format is from 4(440Hz) to 7. I asume that 4 is equal to 5 refence in the smart messaging document.
What is the correct definition of the sclae in rtttl?
<scale> :=
"5" | ; Note A is 440Hz
"6" | ; Note A is 880Hz
"7" | ; Note A is 1.76 kHz
"8" ; Note A is 3.52 kHz
or
<scale> :=
"4" | ; Note A is 440Hz
"5" | ; Note A is 880Hz
"6" | ; Note A is 1.76 kHz
"7" ; Note A is 3.52 kHz
