What is a good way to show the pitch of an audio input??
I was thinking of using the frequency alone, but I've been told is not accurate enough...

[fiddle~] or [sigmund~] ?
Thank you for the answer! I am just reading [fiddle~] Help and it seems that it is the right solution. I guess the third outlet will do the job.. (hope so)
Katjav's [helmholtz~] could be a candidate too, maybe :

Now I'm a bit confused. Can someone define "pitch" please...
All sounds can be described as a sum of many individual sinewaves at different frequencies.
Sounds are considered "pitched" when it is composed of frequencies that are harmonically related. That means that there is a fundamental frequency, and the other frequencies are integer multiples of that frequency. For example, an A can have a fundamental frequency of 110 Hz. The other frequencies are 2*110=220, 3*110=330, 4*110=440, etc. They all contribute to the overall sound, and the ear interprets them as a single pitch. Melodic instruments produce pitched tones.
Non-pitched sounds tend to have many frequencies that aren't related, such as white noise (all possible frequencies at once) or percussion. Cymbals, for example, have frequencies all over the place.
It's not always so cut and dry, of course. Sometimes you can have pitched percussion (like bells), but that is usually because they are designed in such a way that the noisier elements die out while the pitched ones resonate. So the ear doesn't take the noisier elements into account as much. Even melodic instruments often have a bit of noise to them (think the breathy parts of a flute sound).
The more simple answer is: if you can hum it, it is pitched.
thank you very much! Good explanation for a newbie!
Is there a way to describe the pitch of a speech?
I am thinking of the [fiddle~] object and his third outlet which is "raw pitch" (from the Help).. but I'm not sure it will work fine.
A little coincidence, just bought "Musimathics" by Gareth Loy and found this:
2.3 Pitch
Frequency is a physical measure of vibrations per second. Pitch is the corresponding perceptual
experience of frequency.
Pitch has been defined as “that auditory attribute of sound according to which sounds can be
ordered on a scale from low to high” (ANSI 1999). Unfortunately, stipulating precisely what “that
auditory attribute” is turns out to be a complex scientific affair that has spanned across centuries
of research. While our sense of pitch is proportional to frequency, it is also influenced by frequency
range, loudness, and the presence of other higher or lower frequencies. Pitch is limited to sounds
within the range of human hearing, but frequency is not.
There are at least two motivations for developing measurements of pitch: scientific curiosity and
the requirements of music engineering. I take up the scientific interests in chapter 6. Meanwhile,
there is the more pragmatic problem of engineering the pitch range of human hearing for musical
purposes so that we may communicate musically about pitch.
2.3.1 Frequency and Pitch
If we restrict ourselves to simple tones such as might come from a flute or tuning fork, then for some
tone with frequency f we hear some corresponding pitch p. For instance, if the frequency of a tuning
fork is f = 440 Hz, then the pitch p that we hear is conventionally called A440, the pitch commonly
used by modern Western orchestras to tune all instruments together. The reference pitch used by
orchestras has not always been set at 440 Hz but has varied through the ages. It became standardized
at 440 vibrations per second in the early part of the twentieth century (see section 3.2.3).
