Audio Signal Processing in Faust
Audio Signal Processing in Faust Julius O. Smith III Center for Computer Research in Music and Acoustics (CCRMA) Department of Music, Stanford University, Stanford, California 94305 USA jos at ccrma.stanford.edu Abstract Faust is a high-level programming language for digital signal processing, with special sup- port for real-time audio applications and plugins on various software platforms including Linux, Mac-OS-X, iOS, Android, Windows, and embedded computing environments. Audio plugin formats supported include VST, lv2, AU, Pd, Max/MSP, SuperCollider, and more. This tuto- rial provides an introduction focusing on a simple example of white noise filtered by a variable resonator.

Sin su ayuda, esto no habría sido posible. − Finalmente, darme las gracias a mí mismo, por aguantar este ritmo de vida, tener la ambición de seguir y afrontar nuevos retos. Como me dice mi padre: “Tú hasta que no llegues a la Luna, no vas a parar, ¿no?”. Implementación de un sintetizador en un kit de desarrollo de bajo coste Resumen La realización de este proyecto consiste en el diseño de un sintetizador ‘Virtual Analógico’ basado en sintetizadores de los años 60 y 70. Para ello, se estudia la teoría que conforma la topología básica de los sintetizadores sustractivos, así como, los elementos que intervienen en la generación y modificación del sonido. -

Printed in Berlin by TU Haus-Druckerei — March 2007 Proc. of the 5th Int. Linux Audio Conference (LAC07), Berlin, Germany, March 22-25, 2007 LAC07-iv Preface The International Linux Audio Conference 2007, the fifth of its kind, is taking place at the Technis- che Universität Berlin. We are very glad to have been given the opportunity to organise this event, and we hope to have been able to put together an interesting conference program, both for developers and users, thanks to many submissions of our participants, as well as the support from our cooperation partners. The DAAD - Berliner Künstlerprogramm has supported us by printing the flyers and inviting some of the composers. The Cervantes Institute has given us support for involving composers from Latin America and Spain. Tesla has been a generous host for two concert evenings. Furthermore, Maerz- Musik and the C-Base have given us a place for the lounge and club concerts. The Seminar für Medienwissenschaften of the Humboldt Universität zu Berlin have contributed their Signallabor, a computer pool with 6 Linux audio workstations and a multichannel setup, in which the Hands On Demos are being held. -
