1 | And here it's all just tonic, just the basic primordial note upon which all these other tones are built. | |
2 | The system cannot be made to sound any notes other than the fundamental and the various overtones. | |
3 | As in previous studies, the volunteers could not recognise melodies with fundamental tones above 5 kHz. | |
4 | A new Pitch Detection Algorithm (PDA) based on multi-phase filter group is presented in this paper. | |
5 | Wavelets transform is used to detect the pitch period of speech signal, and attain a good result. |
