Time Stretch and Pitch Shift Algorithms in Cubase

hello everybody Andrew Blake from Thedigitalaudiomanual.com Today Let's TalkAbout Time Stretch and pitch shiftalgorithms in Cubase but before we startI want to remind you that there's a linkbelow to the free content navigationguide which is an easy to navigatewebpage with links to all the content onthis channel and besides that in thenear future I'm going to begin addingtips and other bits of information thatwill only be available there you knowthings like simple steps that will getyou started and up and running quickthings that are in the videos but arewritten down in simple steps that serveas quick reminders when you needinformation down the road if you'reworking with programs like wave lab orCubase plugins or the cable guys shaperbox and many many other projects thatare in the works then I know you'regoing to find just like I have that thisis an invaluable study Aid and the otherthing I want to make sure you understandis that this is not a simple PDF this isa constantly updated page that has anyinformation that is new or anytimevideos are changed it's really anythingupdated and once you have it you willalways have the latest informationconstantly updated so if you haven'tgotten it already go to the link belowclick on it and save it to yourfavorites it's my gift to you and it'sabsolutely free Okay so let's getstarted so as you're working with audioin Cubase you will encounter thesethings called the time stretch and pitchshift algorithms these will allow you todo is when you do things like TimeStretch or pitch shifting they will helpyou keep your audio more intact typicalexample is a drum Loop if you speed itup or slow it down these differentalgorithms will keep the hits of thedrum sounding like the hits of the drumit will help you realize more accuratelywhere the actual hits occur or whenyou're using vocals many times and youstart pitching your vocals up or downthese algorithms can help you retain thequality of the vocal or sometimes evenadd an effect if you're trying to go fora specific effect but either way you'regoing to find these in Cubase and you'regoing to see these terms for algorithmsand you'll see a term like standard orelastic or sometimes this mpex and ifyou've never seen them before you'regoing to look at them and go what arethese so let's have a look at thissubject let's start by looking at whereyou're going to encounter these variousalgorithms the first place is right inthe project if you click on a piece ofaudio and you look up on the info linecategory that says algorithm and if youclick in that algorithm category youwill see the two categories of elasticand standard standard are the originalalgorithms and these elastic ones arethe newer ones but again they are bothgood at different times depending onwhat you're trying to do if I quicklybrowse through these if I go to thestandard option there's one for drumsand plucked and pads and vocals so theone that says mix and custom and solothen if I go to the elastic category Ihave time and pitch and tape format timeformat pitch formant tape and then timepitch and tape we'll explore some ofthese in examples as we go along herewhere else will you find these if Idouble click on this piece of audio openup in the sample editor and I look atover these tabs one that says audio warponce it again I will find that samecategory of these different algorithmsanother place you'll find them if I goto the audio part editor and I click ona part and I open it up right now youwon't see anything but if I click on anactual part once again the info linewill light up and there I'll see thealgorithms in the info line anotherplace we'll find these algorithms if wego up to my media come down to open thepool window and in the pool you'll findevery piece of audio that you have inyour project and connected with thatyou'll see a category that saysalgorithm which again you can click onand change these different algorithmsanother place you'll find these is ifyou open up your direct offlineprocessing window many ways to do thatbut if you go to audio down to directoffline processing you've done videos onDirect offline processing but in theprocess category there's a tab up hereif I pick either the time stretch or thepitch shift let me take pitch shift heredown in the lower right again I willhave algorithms and this time I'll finda different set of algorithms findmyelastic algorithms like I had before Ino longer can see my standard ones now Ihave this new category of mpex or MPXand this gives us a whole category ofdifferent algorithms to try as well soyou will encounter these algorithms andthe choice to use them just about anyplace that you encounter audio in Cubaseso let's do an example of how this canactually affect the audio I'm back inthe sample editor and I have this drumLoop and if I play ityou can hear that it's really not lockedto the beat very well so if I go to myquantize panel I have musical modechecked and I've got free warp on hereand the algorithm is set to standarddrums if I go ahead and hit quantizeit puts in some warp markers and does apretty good job of quantizing it if Iplay these drums nowstill need some work in terms of where Iwant the Beats to hit but it'sdefinitely lining up to the beat nowwatch what happens when I change some ofthese algorithms to something differentfrom drums let's go down to standard I'mgoing to put it on pads listen to whathappened to the drum soundsoh you have all kinds of strangeartifacts and this beats in there put iton vocalsso you can hear without the rightalgorithm even though you go through thesteps trying to line things up you canget some real unpredictable results letme switch it back to the standard drumssee now all the hits are nice and cleanI can go back and take these drums andstart moving them to different spots andI'm going to get predictable resultsbecause the algorithm is set tounderstand what drum hits areall right so I've got a vocal sample inhere nowa technique I kind of became aware ofwatching uh Warren hewart video he has avideo on thickening vocals he does it inPro Tools and he has a kind of aspecific way of doing it and it's agreat video to check out and learn thosespecific steps I've done it that way aswell but in Cubase you can do it alittle bit differently but it'simportant to remember that you want toset this algorithm to reflect vocals notdrums or some other option you have inhere so I'm going to go through thesteps really quick and you can see theresult the first thing I'm going to dois repeat this track eight times I'mgoing to bounce each one of these so Ihave unique vocal samples and I'm goingto change the fine tuning on it a littlebitI'm going to go over to the track delaywhich allows these tracks to move alittle bit forward or backwards slightlyout of sync I'm going to continue doingthat to each one of these tracks realquick and you can make some pretty fastwork of this once you get sometechniques down for example I'll use myup and down arrows to move through thesetracks and as I move down I'll slightlychange this track delay a little bit ifI go back through each track and justset the panning far left and far rightfor each one now I'm going to change ofthese algorithms to the vocalsnow I went ahead and put a little bit ofReverb and delay on it as well if youhave headphones on you're going to see ahuge difference here from one singlevocal layered onto itself here it isplayed just the original vocalohI feel the way now when I kick on thethicker vocals with it[Music]and it makes a big difference whenyou're using this algorithm for thevocals as opposed to something else solet's break down some of the meanings ofthese different terms when we look atour elastic algorithm it looks like wehave this whole list but really this isonly a few of them with differentvariations if you look at it closely ithas elastic Pro three different timesand then it has elastic Pro with theword formant after it and that's threedifferent times and then at the bottomit has elastic efficient and there'sthree of those so there's really justthree of these elastic Pros but in threedifferent variations each one of themhas a time a pitch and a tape if youtake any of the ones that have the timeoption they're going to favor timemeaning that if you change the tempo upor down these are going to be the betteroptions if you choose the one that sayspitch back like an example we just didwith vocals or a pitched instrument thisis going to be a better option and thenwhen you use this tape option again thisis kind of a special effect for exampleif I change the tempo on this drum Loopand I put this elastic throw tape on itthen I'm going to get the effect of thetempo slowing down but you're also goingto hear it drop and Pitch trying toreflect what a tape machine does here itgoes[Music]if I change this to the elastic Pro timeand I play this at its original tempobut then I dropped the tempo way down tolet's say 80.gonna hold more of the sound of the drumbut just slow it down the other thing onthese elastic choices the elastic Prothe first three options and the elasticPro with the formant these are the morehigh quality options the elasticefficient is more of a computer friendlyoption these days I would assume that'sreally not a big deal for the most partyou'll always want to use the elasticPro options all right it's going to wrapit up for today as always if you haven'tgrabbed your navigation guide be sure tograb that from the link below this videogives you quick easy access to all

way so today we looked at thepitch shift and Time Stretch algorithmswe kind of talked about what they arewhere you're going to see them like inthe project the sample editor audio parteditor and the pool and then we got intokind of what are they the standard theelastics different examples with drumsand vocals and then we just got intosome of the definitions of the wordsalways working towards getting a betterunderstanding of your tools as alwaysit's great to have you guys here andI'll see you on the next video
