Talk:Pitch shift

From Wikipedia, the free encyclopedia

"Pitch-shifting may be done both in analog and in digital recording" Is it true that only digital recording can do it in real time. —Preceding unsigned comment added by 144.139.85.123 (talk • contribs)

Not with a pitch control, on an analog tape machine. TEAC's old units used to boost or cut pitch by fifteen percent (or a whole step and then some). Zephyrad 04:53, 11 January 2006 (UTC)

"Berry was already in his thirties when he began having hits; his producer wanted him to appeal to the youth market." This reminds me of Leonard Cohen who nowadys sings in a bass register and wonder why he hasn't added sped-up vocals to his more reccent studio recordings. —Preceding unsigned comment added by 144.139.85.123 (talk • contribs)

[edit] Speed shifting

Speeding up and slowing down a recording is not the same as pitch shifting. This needs to be clarified. — Omegatron 15:32, 13 July 2006 (UTC)

The TERM discussed is "pitch shift", which in analog terms DOES refer to the speeding up or slowing down of a recording; the speed control on an analog machine is labelled "Pitch Shift" or "Pitch control". When pitch is shifted in a digital recording, it plays back faster or slower, unless the shifter is set to change pitch but preserve length (which takes some number-crunching).

Hmm... Maybe that's an older definition of the term then?

pitch-shifting or pitch-transposing 

Recording. An effect that changes the pitch (frequency or tone) of musical notes without changing their length, or timing. - Rane

PITCH SHIFTER 

Device for changing the pitch of an audio signal without changing it's duration. - SOUND ON SOUND TECHNICAL GLOSSARY

Pitch Correction 

A process whereby the pitch of a selected track or part can be changed (or corrected) without changing the speed at which it occurs. - Sweetwater glossary — Omegatron 16:56, 13 July 2006 (UTC)

[edit] Pitch correction merge

Pitch Correction and Pitch shifting are related but are two completely different algorithmic processes and are used for different reasons in audio production. Pitch Correction is a note by note process while Pitch shifting is more often used globally on a track or tracks for creative or overall adjustment to pitch. In older eras of engineering pitch shifting via tape adjustment or external digital processors was used for pitch correction, but the term pitch correction is not used interchangeably with pitch shifting and has a more specific meaning in modern times. True you can do pitch shifting using a pitch correction process or you can do pitch correction via a pitch shifting process, but they are two different things so a merge is not needed as per WP:MM Dissolve 22:58, 28 January 2007 (UTC)

I disagree. The processes are very similar and typically (in current digital systems) use the same algorithms. I'd suggest pitch correction should be a subsection of the pitch shift article, since pitch correction is an application of pitch shifting. Granted it is done on a note-by-note basis, but that only makes it pitch-shift with an automated control element. --mcld 11:02, 20 April 2007 (UTC)

Regardless of the technological basis for comparison between pitch-shifting and pitch-correction, the artistic and cultural implications of the two techniques as historically used in popular music are so diametrically opposed that merging the two subjects can only lessen the understanding of either process. Pitch-shifting as used, for example, by George Martin and the Beatles, was done in order to render otherwise natural-sounding performances strange (for artistic purposes). Pitch-correction, as used on many contemporary pop singers, is used to transform otherwise unlistenable performances into seemingly natural (and technically proficient) singing. These two very distinct uses of pitch manipulation deserve separate entries, exactly as we wouldn't lump foreign language translation software and spell-checking into one entry because they both use software dictionaries to modify the words that we type. --Electroniceye 08:38, 21 April 2007 (UTC)
