◆ mtof [1/2]

int mtof ( int midi_note )

friend

◆ mtof [2/2]

int mtof ( uint8_t midi_note )

◆ Q16n16_mtof

Q16n16 Q16n16_mtof ( Q16n16 midival_fractional )

friend

Converts midi note number to frequency with speed and accuracy.

Q16n16_mtofLookup() is a fast alternative to (float) mtof(), and more accurate than (uint8_t) mtof(), using Q16n16 fixed-point format instead of floats or uint8_t values. Q16n16_mtof() uses cheap linear interpolation between whole midi-note frequency equivalents stored in a lookup table, so is less accurate than the float version, mtof(), for non-whole midi values.

Note: Timing: ~8 us.

Parameters

midival_fractional a midi note number in Q16n16 format, for fractional values.

Returns: the frequency represented by the input midi note number, in Q16n16 fixed point fractional integer format, where the lower word is a fractional value.
