Физическое моделирование звука: различия между версиями

[[Yamaha]] подписала контракт со [[Стенфордский университет|Стенфордским университетом]] в 1989<ref>Johnstone, B: ''Wave of the Future''. http://www.harmony-central.com/Computer/synth-history.html, 1993.</ref> для совместной разработки метода цифровых волноводов, и с тех пор большинство патентов в этой области принадлежат им.

 

 

В то время как эффективность синтеза методом цифровых волноводом сделала физическое моделирование доступным для обычного аппаратного обеспечения для обработки сигналов, реалистичная эмуляция физических инструментов зачастую требует использования нелинейных элементов. В этих случаях цифровые волноводы часто совмещают с [[Метод конечных разностей во временной области|методом конечных разностей во временной области]],<ref>The NESS project http://www.ness.music.ed.ac.uk</ref> finite element or wave digital filter methods, increasing the computational demands of the model.<ref>C. Webb and S. Bilbao, "On the limits of real-time physical modelling synthesis with a modular environment" http://www.physicalaudio.co.uk</ref>

 

 

''Примеры методов физического моделирования звука:''

* [[Формантный синтез]]

 

 

* Tension, Electric, Collision, Corpus – входят в состав Ableton Live Suite

* Ultrabeat, EVP88, EVB3, EVD6, Sculpture – входят в состав [[Logic Pro]]

* [[Native Instruments]] Reaktor

* [[SuperCollider]]

* [[IRCAM]] Modalys

* [[Arturia]] [http://www.arturia.com/evolution/en/products/brass/ BRASS] – труба, тромбон и саксофон

* Keolab [http://www.spicyguitar.com Spicy Guitar] – акустические гитары

* Yamaha S-YXG100 + VL и S-YXG1000 + PolyVL (второй выпускался только в Японии). These were basically software-only equivalents to the hardware (and hardware-assisted software) MIDI synth capabilities of the DS-XG cards / YMF chipsets mentioned in the next section. The PolyVL had eight voice polyphony for the physical modelling, whereas the VL and all of the hardware Yamaha VL synths only had one voice, or two for the original VL-1. Like the DS-XG .VxD drivers required for VL support of the DX-XG chipsets, these would work only on pre-NT kernel versions of Windows (9# and ME), and not on NT, 2000, XP, etc. Yamaha quietly discontinued these years ago.

* [[Image-Line]] Sakura

* Madrona Labs Kaivo

 

* [[Korg OASYS]] and [[Korg Kronos]] – STR-1 Plucked string

* Korg OASYS PCI

Various Roland synth models (V-Synth, V-Combo, XV-5080, Fantom, etc.), use a technology called COSM ("Composite Object Sound Modeling") which uses physical modeling techniques to more accurately replicate guitars, brass and other instruments. COSM has been superseded by "SuperNatural", which is also based on physical modeling techniques. Introduced first in 2008 as part of the ARX expansion boards for Fantom hardware synthesizers, "SuperNatural" modeling is used in Roland's [[V-Drums]] (TD-30, TD-15, TD-11), V-Accordions (FR-7, FR-8) and various synth models (Jupiter 80, Integra 7, FA-08, JD-Xi, etc.)
