I've just posted a public beta of Vutu for MacOS. Vutu is the sound analysis program for the upcoming Sumu synthesizer.
A Vutu quickstart video is also online now. I haven't had a chance to write any better documentation yet, and I"m not sure I will before I get the Sumu beta out. However, Vutu in its current form is pretty simple anyway, and most of what you need to know you can find out by fooling around with the dials and listening and looking.
Vutu analyzes sounds using Loris, developed by Kelly Fitz and Lippold Haken at the CERL Sound Group. A detailed intro to Loris is available on Hakenaudio.com: Current Research in Real-time Sound Morphing More publications are also linked from the CERL Sound Group Loris page. Loris is distributed under the GNU General Public License (GPL) and thus, Vutu is also. Vutu's source is available on Github.
Vutu is built on a cross-platform GUI framework I developed called mlvg. Compiling it for Windows and Linux should therefore be a reasonably easy task, but I know there will be a bunch of details to iron out, so I'm not taking that on until after I can make a Sumu beta.
That was a lot of info and links. Why would you want to play with Vutu right now? Some reasons might be:
- You want to get started making your own sound bank for Sumu.
- You have to try out the newest audio software, whatever it is, and this was just released today.
- You enjoy looking at bandwidth-enhanced partials and hearing odd noises.
Each voice of Sumu will be able to play back 64 bandwidth-enhanced partials simultaneously. A bandwidth-enhanced partial is basically a single sine wave, modulated with noise. So at any given instant of time, in addition to frequency, amplitude and phase, it also has a bandwidth, or noisiness. Making sounds out of such partials is a very powerful technique, and I think it's pretty easy to grasp. What's been difficult about additive synthesis is the large amount of control data that's needed. How do you generate it all? My answer in Sumu is to use the familiar patchable interface, but extended so that each patch cord carries separate signals for each partial. This allows sound design in a playful, exploratory way that should be familiar to any modular user. Honestly I think it will be fun as hell.
Thanks to Kelly Fitz and Lippold Haken for creating and sharing Loris. Thanks also to Greg Wuller for helping me get going with the Loris source code, and for utu, which became Vutu. Utu is a Finnish word for "mist" or "fog", like Sumu. Vutu is short for visual utu.
A Metal-capable Mac running MacOS 10.14 (Mojave) or greater.
Vutu is native for Intel and Apple Silicon.
Since it's an analyzer and not a real-time program (except for playing the results), CPU doesn't really matter.
I'm on Windows so I can't try it yet. Is FLAC import supported? If not, would you consider adding it?
Yes, I could add that at some point.
Amazing work !!
Is there a way to signup for the SUMU beta whenever it arrives ?
I've been looking for another additive synth for ages and I'm hyped. seeing your work on Vutu is super nice
Absolutely fantastic.! It works perfectly well. Thanks for sharing. How it will be the the real-time use of this in Sumu? How many Voices?
There's no need to sign up for the beta, I'll announce when it's available via the website.
Sumu voices: I'm not totally sure!
Unbelievably exciting! Thanks so much, Randy! And thanks to Kelly Fitz and Lippold Haken as well. This is a really wonderful development. Can't wait for Sumu, but am at the same happy to wait as long as it takes!
is the link to the .dmg down? i can't download vutu from the link you posted @randy.
Works for me. Did you save the link or something? It will change whenever the version changes.
it seems that chrome blocks the download, at least that's what my browser is telling me. with "save as" and a click on exemption it worked however! cheers
Glad that works. Everyone wants to protect you from evil people like me who might try to give you a computer program.
