time stretch question

Hi, i finally got around to trying to learn how to use and incorporate the time stretch feature in my beats. However, im having a difficult time trying to grasp the concept of time stretch. would someone mind just telling me when i would use time stretch and what uses i would have for it? one question i have is.. is time stretch for recording riffs without a guide beat? for example.. say im going to use the mpc to sample the keyboard riff.. however.. i play the riff without any beats for guidance.. can i then sample that riff.. and then use time stretch to place that riff in any beats i make regardless of bpms???? and also can i use time stretch to alter sounds.. for example..if i sampled a keyboard sound. can i copy the same exact sound put time stretch on the duplicate and layer it over the original to get another sound?? any help would be appreciated.. thanks.

I want to know too dang it.....!

Although I have used it before I really didn't know what the FunK I was doing it just worked.... shed some light shed some light.... plus I use recycle as outlined by the Board of Edamacation (MPC-Tute) and still find that samples from the same song still need a lil editing... will time scretching help fix the odds and ends????

timestretch is used to change the length of a sample without changing its pitch.

but if you try to stretch it too much it sounds a little **** up

the timestretch feature on the mpc is kind of a hard feature to utilize, reason being is that by streching on the mpc the sound quality takes a crap and it takes a minute to process the time strech... I'd suggest using something else like some computer programs do it pretty well and the zoom sampletrack does this nicely too.

AND also the converse - you can change the pitch of a sample without changing its length/speed.

.

true. it can be used to do pitch correction

the esiest thing is to simply get a software programs to do wav editing in. i have wavelab and cool edit.

in these programs, timestratch and pitch correction are two different functions. software processes the change very quickly too so its your best bet if you have a pc

acid is the best timestretching program out, some of the cheaper versions leave artifacts all over the audio but think the pro version is pretty, well, pro...for extreme time stretch use acid.....

i quite like using the mpc's timestretch for that old-skool 'time-stretched' sound as its not great but nor was the time stretch on the early samplers of the day...

This might be of some help.

yeah, but when you time stretch shit doesnt anything take some what of a drop in sound quality, mpc or comp?

i mean i havent noticed much of a difference between timestretching on the comp and on the mpc....

and for computer programs, i reccomend Sound forge... I think cool edit is aiiiiiiiight, Sound forge is more simple IMO

i gettcha, Im just sayin I used to have a zoom sampletrack where you could change the pitch without altering the tempo...thats my only beef with my mpc...

ANY amount of time stretching will change the original quality. It just depends on HOW much you stretch. My advice is to try small stretches and
extreme stretches to see/hear the differences and then go inbetween to find a middle ground somewhere you are happy with that gives you the stretch AND quality you desire.

yeah i know, usually when you stretch shit to much it comes out sounding metallic... but specifically does the mpc's timestretch drop quality more then say a computer and cool edit?

yeah, theyre probably not a whole lot different, like a picture when you enlarge it the pixels of color spread out which kills the quality of a photo, same thing, just a wave form...yeah.

extreme time stretching was used as an effect in early hardcore techno.

Sounds good to me,

yeah, every now and then when creating my custom synths on the Triton I will go extreme and junk. It's different, I'll say that. You would never think something like that has any place in hard hiphop beats but it does, there's a place for everything and everything has a place.
