UltraPitch Manual

Chapter 2 - More about pitch

What is pitch?

Pitch is the subjective property of a simple or complex tone enabling the ear to allocate its position on a fre-

quency scale. The pitch of a trumpet playing the note ‘A 4’(la) is 440Hz, even though the sound produced

contains many other frequencies (harmonics).

What is pitch shifting/scaling?

Pitch shifting or scaling involves raising or lowering the frequency of a sound through octaves (twelve

notes). UltraPitch has a range of between one octave up, to one octave down from the original tone.

What do the terms ‘voiced’ and ‘unvoiced’ sound mean?

‘Voiced’ sound is a sound with a consistent pitch detectable by the human ear. ‘Unvoiced’ sound is a sound

that has no recognizable pitch, such as a collision, a “shhh” sound, or a gun shot.

What is a harmony maker?

A harmony maker detects the pitch of a note/tone and adds a tone to it that can be octaves, or some inter-

val, above or below the original tone.

What is a formant?

Resonance frequencies, such as those from an oral delivery, are called formant-frequencies or simply for-

mants. Formants depend upon the shape, construction and dimensions of the sound-producing source

(speaker, singer, guitar, trumpet etc.).

What is formant correction?

Formant correction alters the timbre (character) of a sound. To demonstrate formant-correction, pinch

your nose and sing a note. Then release your nose (keep singing!) and notice the new sound. The new

sound is a result of the formant-correction you applied when you altered the dimension and shape of your

nasal tract. It’s OK for your kids to try this at home!

What is monotonic pitch shifting?

A monotonic sound source has one pitch at a time and no others, such as a note produced by a trumpet,

flute, or (“monophonic”) synthesizer. UltraPitch can shift the pitch of a monotonic sound source.

What is polyphonic pitch shifting?

A polyphonic sound source has two or more simultaneous tones.A monophonic sound source may become

polyphonic during heavy reverb. UltraPitch is a formant-corrected pitch shifter, and does not support poly-

phonic pitch shifting because in order to correct the formant, the pitch must be determined, which requires

a monotonic (one-note) input.
