New things from Unfiltered Audio

[Julien Unison]

So after a lot of playing around with SpecOps I made another video.

I used my Ableton Push 2 this time for the live performance and I think SpecOps works great this way. Sandman Pro does the delay/reverb.

Amazing!

[Soarer]

Thanks guys
No preset. I picked the effects I found most useful and then just played with Amount and Start parameters. Later I switched quickly through the effects for the glitch sounds and then picked another effect.
The only thing that passes through SpecOps is that single Arpeggiated synth line so it's actually really cool that you can get so many textures with it.

Very cool! Thanks for posting that.

The granulator is something that we've wanted to do since starting the company. Curtis Roads showed me a lot of excellent OS 9 granular software that had crazy amounts of power. A lot of these had, ehhh, "academic" interfaces and/or required a lot of work to use and run. He emailed me to let me know that he will happily consult with us while we design and test it. We plan on doing a granular effect this year, and potentially a granular instrument next year. Our goal is to do something similar to what we did with SpecOps: lots of algorithms and techniques distilled down to a modulation and performance friendly interface.

Oh, nice! Will we see any dictionary-based/matching pursuit granular concepts in there? I've been absolutely fascinated with the concept since reading about it, but can't find any PC software implementing it (and I'm not sure if Scatter for OSX by Roads et al is freely available outside university walls anyway). I've used Michael Klingbeil's SPEAR since my university days and that's let me play with some of the editing possibilities (e.g. deleting 'atoms' above/below a certain amplitude or duration threshold), but I'm sure I'm missing an awful lot when the only item in the 'dictionary' is a sine wave function.

Citation please for this dictionary granularization?

Just got back from NAMM! We had a great time there.

The short version is that it's kind of the granular equivalent of analysis/resynthesis.

Imagine your typical resynthesis type effect - it'll recreate your input sound using a load of sine waves (in its most basic form). Dictionary based granular methods essentially make it possible to resynthesise a sound using arbitrary elements. A sine wave function could be one of those elements, but you could also throw some things that sine waves struggle to recreate in there: some attack sounds, some noise timbres, a little bit of this, a little bit of that - that's your dictionary. Dictionary based granular resynthesis will take your input sound, then look how to best recreate it using the items in your dictionary.

OK...NOW, I'm intrigued ;]

I'm not sure how reasonable I was in even suggesting it to be honest. It seems like an inherently non real-time process. A lot of the more interesting bits (to me) seem non real time anyway. It's the editing possibilities that interest me most. On the resynthesis data you could say, delete all all atoms (as the elements once resynthesised are called) below/above a certain amplitude, below/above a certain length, etc... I mentioned SPEAR in my earlier post as it lets you do this kind of editing, but of course sine waves are the only element in consideration.

Thanks for the simple explanation. So in a synth like this, it's (one of?) my job(s) to define.../choose/weigh the elements of the dictionary?

Honestly, we're getting well above my working knowledge here. My description of what's going is very simplistic and I assume corrections will be incoming.

Here's a demo of Scatter by Roads et al which shows some of the editing possibilities. https://www.youtube.com/watch?v=JgGR6VjTiaA

The interface was apparently inspired by SPEAR (which I've used since my uni days a decade ago) and much of what's possible here is also possible there. It seems the DBM method in Scatter is a lot more robust to noise and heavy transformation, but SPEAR is definitely worth a go if you'd like to check a subset of the editing possibilities. http://www.klingbeil.com/spear/

As an example, all the 'disconnected' lines of harmonics/partials running through the first minute and a half or so in this track of mine were accomplished with SPEAR. This track is nearly all SPEAR and CDP (Composers Desktop Project) working on a 2-note sung phrase. https://soundcloud.com/charityqueen/no-i

I cannot say a lot to this Least I can say, I love resynthesis and do it sometimes... But like this: Audio->Melodyne->MIDI->SomeInstrument

Just realized, UA did VCV Rack extensions... https://www.unfilteredaudio.com/pages/vcv-manuals
A reminder about yet another huge playground. Will try and go more in depth when days have 80 hours.

[Terrafractyl]

Thanks for that info cron!

.

I may be missing something - isn't this simply revoicing? Using Melodyne to extract MIDI from audio and then feeding that to another instrument?

Hey, it is what it is and likely OffT--- I am not familiar with terminology, sounds like you are right
