Perhaps a better title would be "pitch detection" (taking into account
known perceptual aspects). Fortunately, for this basic task (identifying
the pitch of a (pitched) source relative to the Western scale), we don't
need to know how "exactly". Had we waited until this exact knowledge was
obtained, the whole highly-successful pitch/MIDI conversion industry
would simply not exist. To say nothing of query-by-humming services,
voice-tracking karaoke, etc. Exactitude is not always possible.
Sometimes a little fuzziness works pretty well (e.g. time/frequency
tradeoff, which applies to the human ear just as much as to a pitch
detector).

Unfortunately "utter bilge" is not, as far as I am aware, a technical
term. Perhaps you could elaborate. And suggest some non-bilge references
("ballast"?) instead. Easy to make unsupported judgements (and always
useless to the reader) - but on this list it is preferred that some
supportive evidence be proffered! if you have better references, I am
sure the FAQ writers will be happy to consider them.

"Q2.5: How does pitch perception work, and how do I implement it on my
DSP chip?"
Considering the fact that nobody knows exactly how human pitch
perception works how can you possibly implement it on a DSP chip ?
Aren't you supposed to know exactly what you are doing before you even
touch the damn chip ?
I don't even want to discuss the references they suggest - utter bilge
like I said...

Didn't seem like a joke to me. Seems like a perfectly fine general FAQ
to me. I even had it bookmarked even though it was the one I was
thinking of. CHILL ;]

There's some discussion of theory at http://www.dspdimension.com/

You are joking, right ?
Have you read the FAQ yourself before suggesting it to somebody else ?
This is utter bilge creating nothing but confusion.

A friend came across some software for changing playback speed without
distorting pitch. I know I've seen a FAQ that covers the application.
Where should I refer him. He's a musician with a BSEE.
