Although I dont often use the graphic tuner or waveform generator portions of the program, the spectrographic and waveform analysis, accompanied by live pitch recognition and feedback, helps my singing intonation and the harmonics mode gives me useful feedback on formant tuning.
I appreciate the variety of temperaments available, which allows accurate tuning in solo practice for accompanied and a capella works.
It would be nice to have a simultaneous waveform and harmonic display.
