Your voice makes this sound like its a professional documentary! I love it so much!

[BrontoScorpioMusic]

This is just brilliant!

[sonosolomarco]

AMAZING!

[peccoz]

inspiring! thank you very much!

ok.. I'm new to this.. and what do I need..to do this... this looks very very usefull!!!

cycling74 just reconnected the old share page contents. You can download 16 patches to study spectral sound processing - I updated the link in the video information.

really good example, going to check patch out and use open sound control to link with face tracking / color tracking / ipod touch accelerometer data for a performance, ohhhhhh spoke too soon, your link to cycling is INVALID, pity, no patches....

[jfcharles]

Hi there, thanks for your comment. Yes, indeed, cycling74 just updated their web site, and their "user pages" are in "coming soon" state now. Hope they fix that soon. In the meantime, just e-mail me and I will send you all of these patches (you should find my contact when visiting my blog).

I have all these patches if you want them...Brendan

[interactiveartsNI]

Cheers Brendan, but jfcharles has kindly mailed them to me, will have a mess around with them and see what I can do, do you know any dance groups in belfast brendan who might be interested in a performance using face/color/motion tracking/dmx lighting and the likes, using wii and/or ipod touch?

[ronnie9253]

try giving Keith Acheson a ring, the asst. manager at the Crescent Arts Centre in Belfast. That's all I can think of at the moment. Shall we trade email addresses?

[jfcharles]

Thanks for the comments. Yes, reading the article may be useful to get more insight. Otherwise, just playing with the Max patches can be fun. You can even use them without a Max license: you can use Max runtime and play with most of them, generate sounds, and maybe record the sounds (using some audio routing software such as SoundFlower or Jack, etc).

Hi I read your article and appreciated it very much.

spooky almost orchestral sound in places

[strictpolicy]

great sounding tstretch

[Quadrange]

highly impressive

[littlescale]

This is a fantastic video, I have downloaded your Max/MSP patches and I look forward to playing with them! Thanks for your time and effort in putting all of this together :)

[bakagaigin]

So now I know how Klimek gets his sound! neato.

[midinerd]

jf! Glad to meet you, I will friend you now.

[grendel7]

This is great. Is it possible to do this with incoming audio and not just a loop? Is there a patch available for download?

[jfcharles]

Thanks for your interest. It is indeed possible to time stretch a sound in real time: just record the sound directly in spectral domain, while you playback the sound with the time stretching algorithm. This is exactly what I designed for my composition "Plex" for solo instrument and live electronics. The best thing is that you can time-stretch the beginning of a sound before it is completely recorded. Not enough characters, see link to patches in next comment.

The Max MSP Jitter patches are on the cycling74 web site. See link in the video info (standard position is top right in your browser). Use for instance "Phase Vocoder" #3 as a basis. Add #8 to get the transient-controlled playback rate. I add in the video info a link to a recording of Plex - you can hear the real time extreme time stretching from the first note on (live recording).
