Pitch Perfect
Pitch perfect helps you train your voice by picking out the pitch that you are singing at. Click on the play ▶ button to start detecting the pitch. Click on the stop ▣ button to stop, and on the ►‖ button to pause or resume pitch detection. The pitch is shown both as the closest note, and the frequency.
If you are using the built-in microphone, the algorithmically detected pitch is generally 10% lower than your true pitch. To correct for this, the default pitchfactor is set to 1.087. If you are using headphones, the detected pitch will usually be accurate, and you will need to select pitchfactor as 1.0 from the Settings ⚙ menu.
Currently the vocal range of detection is from C2 to B4, and we are working on an update that will expand this. All notes are based on A4=440Hz.
If you are looking to select a pitch for singing Carnatic music, a typical primary pitch (for the root note Sa) to aim for is C3 for Men, G3 for women, and A3 for children. The other notes are derived equally spaced from the root note. For example, when Sa=A3, for the standard scale (Shankarabaranam), Ri=B3, Ga=C3, Ma=D4 Pa=E4, Da=F4, Ni=G4 and Upper Sa=A4.
We now have the option of the scale that is being displayed. When you use the Western scale, you can set the low and high notes of the range you are aiming at. For Carnatic scale, you choose the value of the root key Sa (typical C3/G3/A3), and the Raga that you want. This reduces the 12 note positions to the actual 7 note positions used by that raga. Maya Malava Gowla uses S R1 G3 M1 P D1 N3, and the Raga Shankarabaranam uses S R2 G3 M1 P D2 N3.
