Phonature PhonTuner is an advanced guitar tuner that can be used to tune violin, piano, and vocal practice like barbershop quartet. It is the FIRST real-time precision tuner to detect off-tuned notes in continuous performance and a cappella singing. It is the best companion for choir, musicians and studio / bandroom professionals. You even use it to tune your DRUM and other tricky instruments. With PhonTuner for your mobile phone, you don't need standalone tuners any more.

Named by many satisfied customers as their most used PDA software, the PhonTuner gives you excellent value for money.

Enjoy seeing the secrets of popular singers' tonal accuracy and temperament used by top violinists ;-) It can also alerts when you need to tune your piano.

Based on the Mathematical Cochlea of Phonature theory, almost perfect pitch measurement over a 3 octave range can be clearly seen. Calibrated Sound Texture pattern in the middle reflects the timbre of sound and reveals fusing of multi-part voices.

PhonTuner indicates the playing note on the Mathematical Cochlea with a big dot and needle for you to see clearly whether it matches the target tone. Singing mode automatically shows singing or whistle in the chromatic scale; users can define target tones for up to 6 strings in Custom mode.

Features:

1. Show the tone of the loudest note in multipart music (more than one sound input) or noisy environment.
2. Tuning Modes with tuning marks for Cello, Viola, Violin, Guitar.
3. 2 Custom Tuning Mode for user to define up to 6 target notes.
4. 1 Singing Tuning Mode for vocal tuning with automatic range tracking.
5. 1 General Mode for general instrument tuning with automatic range tracking.
6. Real-time indicator showing accurately the pitch of music. Even off-tuned notes of live performance, recording and CD can be located.
7. Fast note tracking for singing & vibrato practice and to follow quick melodies. The Symbian UIQ phone (P800 P900) can now show depth of vibrato clearly.
8. Frequency locking for musical instrument tuning to hold the frequency value of a tuning string when the sound is clearest.
9. Fading effect for easy identification of pitch and error variation.
10. Adjustable frequency scale to set reference note A4.
11. Calibrated Sound Texture pattern reflects the timbre of sound.
12. Background noise suppression.
13. PhonTuner is a Shareware that stops after 60-second on trial.

PhonTuner for vocal training
Get the initial 'do' tone correct by adjusting your air pressure and muscle tension. Notice any unintention tone fluctuation. When you have get a stable 'do', practice the whole octave do-re-mi-fa-so-la-te-do' to see whether the fading needles all fall on the marks C-D-E-F-G-A-B. Improve the tone that is most seriously off-tuned in conjunction with its neighbouring tone. After mastering the basics, look out for subtle errors such as pitch drop near end of note indicated by the needle pointer rotating anti-clockwise.

Note: Application of calibrated Sound Texture

1. Achieve perfect pitch tuning for just intonation.
2. See fusing of consonant notes and chords.
3. See subtle time variation of musical notes such as that of church organ.
