Timestretch 1 minute to 10 (or more)

benthomas1977 · Post by **benthomas1977** » Sun May 22, 2005 11:40 pm

Anyone do this with Live? I am trying to do some EXTREME timestretching without clicking or side effects or pitch changes.. Basically I want to turn a 1 minute violin clip into 10 minutes and then add some things over it..

Anyway, I have lookeed into trying to do it in Max but gave up and so far I have not had much luck getting it to work in Live the way I want (Ive tried tones, texture, beats etc in the warp window already)

Anyone know a plugin, shareware, MAx patch or way to do this effectivley in Live? My computer is definitley fast enough to handle it..

Thanks!

i know i have seen some offline command line interfaced extreme timestretcher before, but I doubt anything will streth 1 minute to 10 without some kind of audio artifacts.

i think you would be better off slicing up your violin sample. use recycle or something and get a .wav for each note you need in your 10 minute long violin piece.

now rather than try to timestretch these, find the correct loop points for each note you want so you can play your loop notes from the violin sample as slow as you want (even 1000% slower).
you will probably want to use a sampler that is slightly more advanced than simpler so you can split each note into its own keyzone so you can play it all from 1 midi performace/track.

alternatively if you have a decent violin patch for a sampler you could simply play along to the violin sample and learn it by ear, then record that to a midi clip (get the notes right, you can adjust the timing errors and add vibrato and swells and all that later). now you can simply take the midi clip and stretch the notes out to wherever you need them to be.

or simply play the violin part (via midi) as slow as you want it to be in your song. once you know which notes you want it should be pretty easy to play something 10x slower.

Thanks for the advice..

I want to achieve something like this guy did with beethoven basically:

There is White Noise Dopplemangler..... It is resynthesis.... Haven't heard it, but imagine it'd be a cool toy.

I did a track once, where a one-second sample was stretched to 1½ minutes, and then layered - sounded phenomenal!!!

Granulab, if you're on pc - you want some kind of extreme granluar processor, preferably with many adjustable/randomizable parameters, so that it won't go machine-gun on ya.

Dude that Beethoven's 9 is crazy. I think an Akai sampler will do that.

Beethoven was done under Linux free and open source SND editor.

on Mac:

Tom Erbes "Soundhack" is famous for doing these things. It it freeware and does convolution, fft based time strech, binaural spatialisation and lots of things more!

should be easy to find via google.

on a Mac, AudioSculpt (software) or Kyma (software&hardware) can do this....
I time stretched a bell sound 1000% in AudioSculpt with no artefacts

Some discussion here too.

soundhack is www.soundhack.com

i would be very interested to hear a 1000% timestretch that has no audio artifacts, did you only do a bell sound or have you tried with any kind of melody or polyphonic material?

sorry, but that Stretched Beethoven sounds pathetic. The idea represents everything wrong with Sampling and electronic music. talk about a complete waste of time. This officially ceases to be music, and becomes a discussion of whether its even art.

Thats no comment on what anyone here is doing, just seems like the Beethoven is , perhaps, the dumbest idea ever.

"timestrech with no artefact"
Are you folks kidding ????

I wounder if the people who talk about the sound quality of different "audio engines" would agree on this

iiiifffff yoooouuuuuuu ttttttthhhhhiiiiinnnnnkkkkk thhhhissss is proper oxford english you may also find a timestrech with no artefact.

Okay, maybe this is too ironic. All I want to say is that a timestrech IS an artefact. It only depends on how you like the result.

I quite liked the timestretch of the glorious Ninth, by Ludwig van.

But then I often listen to quite ambient stuff when I am working on website code, so it fit right in with my other playlists.

I was impressed with the relatively glitch free stretching myself, I expected worse. The tonalities were interesting to me - still very definitlely strings and vocals, voices, etc.

Although I guess it depends what you like as music whether you actually enjoy it. I still listen to Fripp and Eno's Swastika Girls after 20 years. Its a similar deal for me
