Founded in 1998 in Montreal, Quebec, Applied Acoustics Systems is a pioneer in physical modeling synthesis software. The company was started by Marc-Pierre Verge and Philippe Dérogis, both trained musicians who completed doctoral research at IRCAM in Paris — Verge specializing in aeroacoustics and Dérogis in vibro-acoustics. Their scientific backgrounds in musical acoustics became the foundation for a product line that simulates the physics of real-world sound production rather than relying on samples or traditional waveform oscillators.

The AAS catalog spans a range of virtual instruments and effects available as VST, AU, and AAX plug-ins. Lounge Lizard EP-5 is their acclaimed electric piano, praised for its realistic tine and reed modeling. Chromaphone 3 is an acoustic object synthesizer that generates sounds by simulating the interaction of mallets, hammers, and resonating bodies. String Studio VS-3 replaces traditional oscillators with modeled strings, while Strum GS-2 offers physically modeled acoustic and electric guitar performance. Ultra Analog VA-3 covers classic analog synthesis territory, and Multiphonics CV-3 provides a full modular synthesis environment. Objeq Delay 2 rounds out the lineup as a creative delay effect built on physical modeling.

AAS products are used by electronic artists and sound designers including Richard Devine and Amon Tobin, who has contributed a preset collection for the platform. The company occupies a distinct niche in the software instrument market, with physical modeling at the core of every product rather than as an afterthought.

Applied Acoustics Systems has 123 products cataloged on Equipboard, including Soft Synth Presets, Expansion Packs, and Synth Plugins. Their gear is featured by 15 artists, with the strongest followings in Electronic, Rock, and Funk / Soul. Notable users include Richard Devine, Orbital, and Rob Swire. Most Applied Acoustics Systems products fall in the mid-tier range — professional-grade without flagship pricing.
