      Digidesign's Pro Tools studio softwarehas had it for longer than the Antares has been around. I think the first mac versions did it. Hence the careers of most MTV staples.

      For example, if you know what to listen for (hard 'edges' to notes on vocals) you can hear it all over Britney's music.

      One interesting quote from the article:

      MIT's Vercoe, who lauded Taito for finding a way to bring the sound synthesis technology to market, said pitch correction with Csound had been demonstrated long ago. It could even convert a spoken voice into melody, in real time.

      "It's in the technology. You just have to switch it on," he said.

      This makes me think that Vercoe did NOT ship the pitch correction "switched on." My suspicion is that this is due to IVL's patents. IVL is a Vancouver, BC company that has been marketing formant-preserving pitch shifters for quite some time now. IVL's technology is licenced by Digitech and TC Electronics, among other companies. One of IVL's patents makes claims on the idea of pitch shifters that automatically harmonize and correct pitch.

      Personally, I think that IVL's claims in this area are somewhat tenuous. They have taken a pitch-shifting algorithm that they did not come up with (the algorithm in question was originally from a Computer Music Journal article in the late 1980's), and added a few features that ARE obvious to those "skilled in the art." Still, it sounds like Vercoe didn't want to take any chances. It seems like Vercoe provided a pitch output from the pitch shifter, and let Taito do what they want with it. Nice way to sidestep any legal issues.

      Antares uses the same basic algorithm as IVL. Both companies have their own proprietary pitch detection algorithms.

      It is interesting to see that Extended Csound is still up and running. I thought that it was pretty much dead in the water since 1999 or so. Hmmm...

      Pitch correction boxes are beat (no pun intended).

      They work "sort of ok" for simple harmonies, but as soon as you try them with complex harmonies they kind of suck. Plus they push the voice to the pure tempered tones, which is unnatural for a sliding instrument such as the voice. A natural voice (like a violin) will lean microtones off from the tempered pitch in the desired direction of the tendency tones. The result of pitch correctors is a very artificial sound.

This is about the time I start explaining to clients that they need to seriously consider if they want to use this effect or not.

      In moderation, it can helps vocals, but can be done far better manually - ie., non-autotune. On my site, one of our latest interviews, Steve Duda of Nine Inch Nails (or at least the latest album) discribes some of his techniques for doing this:

      http://interview.sonikmatter.com/duda/

      I personally would use a piece of software called Melodyne. Its not real time, BUT has some of the most natural algorythms around. It is practically a Pitch Word Processor. You can leave in as much vibrato as you want, kill it all together (like most Autotune apps above) or even add it naturally for those that don't know how to articulate it very well. You can shift notes as far as a 5th before they start to sound funny, and it still keeps all the tied notes together so that you can slide between pitches without the sudden note being triggered as is so commonly found in todays image concience talent free musics.

      I personally know a lot of folks that make their bread and butter fixing vocals for the stars and I'm not against it at all...I just wish the producers would get a little more credit as they are the ones doing all the work these days. Everyone has a natural desire to express themselves, as noted by the Karaoke main heading, and this sort of thing allows people to focus more on being creative instead of blindly honing a talent that can only go so far (face it, some people are never going to be able to sing naturally no matter how much practice...I'm one of them).

      The problem comes when someone tries to be deliberately counter-tempo... it doesn't work any more. Of course, turning it off fixes the problem...

      Why be counter-tempo? Often, especially if you're doing something unusual like singing a harmonic of the original pitch, it actually underscores (pardon the pun) the original work better.

      Songwriters (or composers) write for the voices in their heads, or to specific types of voices that they expect to be singing their work. Sometimes some tweaking can make things sound better, especially if you're not their "target" performer. For example, I can imagine a barbershop quartet doing a really awesome cover of "Closer to God," but certainly not by singing it exactly like Trent Reznor does...

    Man of La
    Mancha, and brought new flair to Baby Got Back by Sir Mix Alot. In the
    beginning I was a scared lone singer up on stage, my voice was terrible and I
    was afraid.

    other singers and start around 6:00. Each song I conquered represented a fear,
    so in essence, I was conquering my fears.

    "The Rat Pack" We got other singers into this clique and sort of set
    the place on fire not only with our alcohol finely tuned voices, but with our
    stage presence and showmanship as well.


    The rat pack ended when Frank Sinatra had a kid. I miss those harmonic
    days of bliss long since past.

    it to this comment, I honestly have to say that I don't think this will totally
    help all people. You still have issue's with stage fright, crowd response,
    the singers harmonic vocalizations and how well they dance around and put on a
    show.

Done very carefully, yes you CAN clean up anything.

    This new machine proposes to take the engeneer's seat as well as the processing equipment's. It will most likely read a signal telling what pitch the singer should be at and analize the incomming signal from the mic and based on a comparison of the two shift up or down.

    One problem I have always noticed with live, real-time pitch shifting (NOTE: not auto-correcting, simply pitch shifting) is there is a delay, a millisecond or two, but enough to be audible. Methinks adding all the analysis time into the mix will add a little more delay and the singing will sound off!

  35. Butchery isn't fun by Goonie · · Score: 2
    Having high-pitched, untrained female voices intermittantly scream into microphones (which seems to occur at least once at most karaoke events) isn't funny. It's just painful. Physically. Bad male singers are merely laughable.

    However, a pitch bender isn't the solution I'd prefer for these people. Personally, I'm thinking tasers :)

    I'd still be interested to see exactly what they'd come up with for real-time pitch correction though. I wanna see how it works.

    The only way I can see to do it is to assume the singer is wrong. Always. (This totally removes the ability for any deviation from "right", but how else could they know) At any given time, you know the Hz of note they're supposed to be hitting, so you just mod the vocal input to said Hz and you're good to go.

    But there's gotta be some fuzziness to the algorithm to find the how the vocal input lines up with the actual rythym (nobody's going to be exactly on time, especially when you'd probably have to be sampling for it at an absurdly quick rate) as well as some fuzziness in the Hz itself...it's possible to recognize a bend, technically, you could stick it in there as long as you wound up on the right note. I think I'm just more interested in how the hell they think they're gonna get it to work decently enough to use...

    But I'd still take it anyday for the transposition...very useful for all those songs that just need to be a half step lower/higher to fit in my range!
