Aerophones in Flatland: Interactive Wave Simulation of Wind Instruments

We present the first real-time technique to synthesize full bandwidth sounds for 2D virtual wind instruments. A novel interactive wave solver is proposed that synthesizes audio at 128,000Hz on commodity graphics cards. Simulating the wave equation captures the resonant and radiative properties of the instrument body automatically. We show that a variety of existing non-linear excitation mechanisms such as reed or lips can be successfully coupled to the instrument’s 2D wave field. Virtual musical performances can be created by mapping user inputs to control geometric features of the instrument body, such as tone holes, and modifying parameters of the excitation model, such as blowing pressure. Field visualizations are also produced. Our technique promotes experimentation by providing instant audio-visual feedback from interactive virtual designs. To allow artifact-free audio despite dynamic geometric modification, we present a novel time-varying Perfectly Matched Layer formulation that yields smooth, natural-sounding transitions between notes. We find that visco-thermal wall losses are crucial for musical sound in 2D simulations and propose a practical approximation. Weak non-linearity at high amplitudes is incorporated to improve the sound quality of brass instruments.

Can you download this?

great software, i really enjoyed the visual representation of the functions of the different reed instruments. This would be a great software for music schools, great respect, keep up the good work.

[@PAYPALMEAARONLYSTILA]

really most amazing ever. The ai and code development but also its use. In action. This is amazing amazing to see never mind use and create. What. Im still like blown away how much I learned by watching. Amazing. How stuff works. crazy the computer and virtual design then music from vibrations that feel good because they vibrate your brain in a way that makes you release compounds that make you feel good! Crazy. all of it.

It doesn't use AI.

Love it!

I was thinking about trying to program this myself but if this is on Microsoft Research this might just be out of my capabilities ^^

[@thepiedpiper9801]

For sure it is : )

[@SamChaneyProductions]

Is there an online-accessible version of this model anywhere? I would pay good money to have access to this model, or be able to run it on my own GPU. This would be incredibly helpful for woodwind instrument makers like myself, and I'm also very interested as an engineer and software developer.

[@jasonlandry1035]

When is this going to be available and how do we purchase it?

[@Antsaboy94]

I don't know. It sounds a bit... ... two-dimensional.

[@nyuszi36]

Was there a paper published for this?

[@jasonevans473]

I want this :)

[@pipolwes000]

As a retired band kid, I was hoping to maybe see how your software handles a model trombone (my instrument), but neat tool regardless

[@SHAMANDANCE]

What about 3D simulation? And can you give more information about used model and how it implemented on gpu? thanks! really interested in this simulations, since I'm sax\flute player and physicist. p.s. it should be interesting to compare simulated clarinet in the room (with wave reflection) with the real clarinet. (but maybe this simulations becomes not real-time in that case?) similar to this video (also in your channel) Precomputed Wave Simulation for Real-Time Sound Propagation of Dynamic Sources in Complex Scenes

[@mieggiel2]

Any luck modelling it? I'm and engineer and am trying to do the same to design speaker cabinets

[@incription]

@@mieggiel2 There are papers that cover 3d sound modelling that are in much higher resolution with greater fidelity, however they may take hours to render at a time. See these videos: kzbin.info/www/bejne/qKTOlX97oZVogas kzbin.info/www/bejne/oajUnphuoqqasJY kzbin.info/www/bejne/hn62h2p5n6eokKs

tuning is important lol

[@talesdemidioful]

can you reverse a sound into a instrument? i can

[@SamuelWooPiano]

How? May I ask?

[@talesdemidioful]

@@SamuelWooPiano deep learn Ai, it got perfected with brass sounds, but the project have been halted for years

[@SamuelWooPiano]

@@talesdemidioful Interesting! Thank you for replying. I wonder if it is possible to achieve that using some high level mathematics. (I know very less about physics and computer science)
