Special thanks to f.e chanfrault for the windows port.

cpPan~ object

March 24th, 2006

This object implements a constant power panning formula and applies it to any input signal. Panning info can be sent as audio or control data. Uses a lookup table, so it is very efficient. Also included in the granular toolkit.

Hipno Released

October 10th, 2005

Hipno is collection of over 40 audio plug-ins that is hard to categorize. The individual effects feature granular techniques, spectral manipulations, filters, delays and wild hybrids in between. Additionally it features a truly unique control interface called the Hipnoscope and XML import/export of presets. I worked with Electrotap to develop Hipno and Cycling’74 is handling the distribution and sales of this product. Visit their website to find out more.

mini-concrète

September 9th, 2005

“mini-concrète” was composed as an exercise in self-imposed limitations when faced with the myriad possibilities of the modern digital audio software. Only one channel of sound is used making the pacing and ordering of sound events the sole focus of attention. For a composer whose pieces usually focus on the interaction of slowly changing layers, this brief and compact work stands is a stark contrast.

Concert Review SCI Region IV Conference

December 8th, 2003

SCI Newsletter, Issue XXXIV:1.

EXCERPT – The third and final day of concerts for the SCI Region IV conference started after a paper session with an afternoon concert featuring several works for interactive electronics and various forms of new media.

Overall, the pieces and performances of this final conference day were well worth the trip many made to be present.  They showed the great variety of musical styles being explored by SCI’s members and reaffirmed the organization’s commitment to ensuring the performance of contemporary music by outstanding musicians at its annual conferences.

Music technology in higher education: different models, common issues and future trends

October 2nd, 2003

ATMI 2003 National Conference in Miami, FL.

Co-authored with Peter V. Swendsen.

EXCERPT – Programs in music technology certainly have individual approaches to teaching their students, emphasizing different aspects of the field in their curriculum. However, the differences are magnified in part by the multiplicity names these departments and research centers use to identify themselves. Names and acronyms such as CCRMA, TIMARA, iEAR and CARTAH come to mind. With their differences in the foreground, it can be difficult to see what they have in common beneath the surface. This paper will examine the differences between specific music technology programs in an attempt to identify the similarities in their approaches to the topic, as well as common issues that face these programs. We will also synthesize our observations about these programs and attempt to develop a theory for comparing these emphases within the field. Based on our findings and conclusions, we will then turn our discussion to how technology can act as a hub for arts pedagogy as a whole and not just music.

One question that we should address before diving into the topic is our motivation as authors and the unique perspective our experience allows us to bring to the topic. We are both, admittedly, young scholars at the beginning of our academic careers. But we are also part of a newer breed of students that have been able to pursue music technology as our subject of primary interest throughout our student careers. We were able to seek degrees up to the PhDs that we currently pursue that fall under the umbrella of music technology, a relatively new phenomenon for our field. It is from this perspective that we present our findings, as students who had to search through the myriad of schools offering programs fairly recently in order to choose the best fit for ourselves. We also present this paper as young academics, finding our way in our chosen field of study, and humbly submit it to those more established in the field in the hopes that it will encourage more dialog on these issues.

Understanding the Perception of Granular Processing

July 15th, 2003

SMPC 2003 National Conference @ University of Nevada – Las Vegas.

Co-authors: Gary Kendall and Scott Lipscomb.

EXCERPT -Granular processing of sampled audio signals (Roads 1985; Traux 1987) is a technique that has experienced increased interest in recent years. This processing technique has origins in the work of Dennis Gabor and his concept of the acoustical quanta (Gabor 1947), which was developed in response to perceptual research findings. He asserted that, “it is our most elementary experience that sound has a time pattern as well as a frequency pattern (Gabor 1947, p. 591).” Although several software applications are now widely available for realizing granular processing effects (Roads and Alexander 1997; Behles, Starke and Roebel 1998; van der Schoot 1999; Rolfe and Keller 2000), these programs have done little to clarify the perceptual connection between interface controls and audio output, a problem that has persisted since the first computer implementation was reported twenty-five years ago (Roads 1978). A better understanding of how the audio output is perceived is a necessary precursor to the development of a simplified interface that would require the computer “to interpret how to approximate a desired result” (Roads 2001a, p. 27).

In order to further this goal of understanding the perception of granular processing better, the author has conducted a series of three experiments based on models found within studies of musical timbre (Grey 1977; Wessel 1979; Kendall and Carterette 1991; Iverson and Krumhansl 1993). These studies have employed a method of exploring the topic using a similarity-scaling task. Subjects would listen to a series of pairs of sounds, rating the similarity of each pair member to the other while moving through all possible couplings of the stimuli. These similarity ratings were then averaged together and used as the basis for formulating a multi-dimensional scaling solution (Shepard 1962a, 1962b; Kruskal 1964a, 1964b). MDS uses these similarity ratings to produce a graphic representation of the relationships that exist within that data. Stimuli that are viewed as similar will be placed in close proximity to one another, while those viewed as dissimilar will be have a greater distances between them. The differences are represented in a single graphic plot of points representing the stimuli used. This seemed like an appropriate method to employ in our study, however we must emphasize that we are not attempting to draw connections between the results of our study and those found in timbre research. Our comparison is simply with their experimental methods.

Journal SEAMUS – Granular Toolkit v1.0

July 9th, 2003

Journal SEAMUS, Volume XVI:2, pp. 34-46.

ABSTRACT – Since the generation of granular textures was first automated using a computer (Roads 1978), granular synthesis has grown to become a popular tool for creating new sounds in electro-acoustic music. Many effects can be achieved through the granulation of sampled sound including time compression (Jones and Parks 1988) and expansion (Truax 1990) independent of pitch alterations. Such effects can be created using Cycling74’s Max/MSP software, allowing them to be utilized in real-time. However, the software does not include sufficient externals to meet the efficiency and flexibility needs for creating such effects. This paper details a collection of externals and abstractions for Max/MSP that the author has created with the aim of meeting these needs.

Griesinger Reverb v2.2

January 6th, 2003

Creates a stereo reverb in the style of Griesinger as detailed in Jon Dattorro’s September 1997 AES article.  The algorithm is similar to those found in the classic Lexicon reverb units and delivers a nice de-correlated stereo images.  Available in vst classic and vst carbonized versions for use in OS 9 and OS X respectively.
