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