| holger@0 | 1 function freq = midiPitch2Freq(midiPitch, tuningFreqInHz) |
| holger@0 | 2 % freq = midiPitch2Freq(midiPitch, tuningFreqInHz) |
| holger@0 | 3 % |
| holger@0 | 4 % converts midi pitch index to frequency given a tuning frequeny |
| holger@0 | 5 |
| holger@0 | 6 freq = tuningFreqInHz * 2.^((midiPitch - 69)/12); % midi pitch 69 belongs to A4, the standard pitch, for which the tuning freq is given |
