OpenMusic 6.7, Audio Architecture, and LW-Linux Version
J. Bresson, D. Bouche, A. Vinjar
The principal addition in version 6.7 is the new modular Audio and MIDI architecture, allowing better integration with rendering engines. This new architecture has allowed at a first glance to extend the functionalities of the Audio Player in OpenMusic, offering more flexibility in audio output control. The new version also integrates the new OM-Faust library, allowing the creation and compilation of audio effects and synthesizers using the FAUST programming language as dynamic, on-the-fly modules loaded on different audio channels, that can be controlled interactively or automated.
OM 6.7 has also been ported to LispWorks Linux in a collaboration with the BEK center. The Linux version also uses this new architecture to interface varied open source systems for MIDI and audio rendering.
SoMax
L. Bonnasse-Gahot
SoMax is the new prototype technology out of OMax for controlled and arranged live improvisation.
J. Bresson, L. Bonasse-Gahot, D. Bouche, A. Vinjar (Musical Representations Team, Ircam)
15:30-16:00

In this talk I will present my recent developments for the integration of spatial sound synthesis in computer-aided composition, carried out in collaboration with the Music Representation team at Ircam. More precisely, I will discuss 3 libraries for the computer-aided composition environment OpenMusic: OMPrisma (for spatial sound synthesis), OM-SoX (for multichannel sound processing), and OM-Pursuit (for dictionary-based sound modelling). After introducing the libraries and their respective functionalities, I will demonstrate how they can be used in combination, forming a high-level framework for spatial sound composition.

A demonstration of the latest version of the TIAALS software (Tools for Interactive Aural Analysis) being developed as part of the project ‘Technology and Creativity in Electroacoustic Music’ (TaCEM) based at the Universities of Huddersfield and Durham in the UK. The software enables users to investigate electroacoustic works imaginatively using an interactive sonogram, selecting regions in time and frequency and auditioning them in real time. These can then be used to create analytical charts that are both interactive and aural. Another feature of the project is emulation software developing greater understanding of how technology influences creative processes.The overall project aims to develop greater understanding of the creative and technical processes in EA music and their interrelation to the benefit of researchers, student composers and general public. Eight case studies are being studied in depth, 3 of them works produced at IRCAM. The project is funded by the UK’s AHRC.

With the development of upcoming Ultra High Definition TV standards and the emergence of immersive audio systems in movie theaters, audio technology companies and standardization organizations (such as MPEG, EBU and ATSC) have begun developing next-generation multichannel audio technology applicable in the cinema and broadcast industries. MDA (Multi-Dimensional Audio) is an open and future-proof multi-channel audio content production and interchange format designed for the creation, archiving and distribution of immersive audio content for the cinema and broadcast industries. It extends the existing multi-channel audio formats to support three-dimensional sound field encoding and the addition of a plurality of audio object channels accompanied with positional rendering metadata. This new paradigm allows breaking the current constraints tying the creation format to the playback configuration, while enabling a more natural listening experience and a new level of innovation in entertainment services and media.

11:00-11:30
As composers, we have often felt the need to integrate the complexity of results derived from computer-aided composition with the logics of real-time interaction. While very developed tools are available in each field, we did not find a way to easily bridge them. Moreover, our perception is that this need is shared by an increasingly large number of composers. bach – automated composer’s helper is an attempt to answer this problem: a library of Max externals and patches aimed to bring sophisticated tools for musical notation and formalization into the real-time world, along with a data structure capable to support the complexity of musical representation.

A methodological approach to sound design will be presented through the development of a sample application
in watchmaking industry, led by Ircam SPD Team, and in association with the composer Sebastien Gaxie.
The objective of this project is to achieve the sound of a set of watches called “minute repetitions”;
it includes three phases:
• the elaboration of a set of sound loads: from a corpus of reference sounds, timbre space, preference cards, and a series of portraits allow to characterize semantic attributes that constitute the target sound.
• the phase of creation, led by composer S. Gaxie based on analysis of data from the first stage .
The work resulted in the implementation of several approaches , especially in terms of sound synthesis (additive synthesis, physical modeling via Modalys, etc.) .
• a validation step which is to examine the various proposals in the light of criteria of sound typing
initially set and leads to a small set of optimal solutions.
Nicolas Misdariis (Sound Perception and Design Team, Ircam)
12:30-13:00
Germination is a piece for 13 musicians, electronics and vegetal and electronic materials. It was created during the Manifeste festival in Juin 2013 at Ircam. The idea of the piece is to infer he architectural particularities of a site. The piece takes as model the growth model of plants, in form of a concert-installation in two parts: The first part, for ensemble and live electronics, is played in a concert hall ideally located underground, and the second part is electroacoustic, produced in an open public space, using fifty small speakers. The form and the musical material in Germination all came from the world of plants: generative processes, directivities, root growth models and fractal forms.

Stephanie is a musical language in form of a container using Lua, Esterel, Action Script 3, Java, Max and Skipper. It is based on a Subsumption architecture, a multilater presentation with a persistent database for representing the actual state of the system. In Stephanie, subsumption is the organization, reorganization and behaviors that exist and interact at some point between the musician and the interactive tool. This presentation will demonstrate the language architecture and its use in musical applications.

This presentation extends certain aspects of the work presented in the Thinking Inside the Box Project, by exploring efficient software-based methods for improving sound reproduction within the concert hall. The key problems discussed are: (1) the detrimental effects of room acoustic and/or sub-optimal loudspeaker design on the frequency response of amplification systems for concert use; (2) the non-ideal frequency responses typically encountered when using close-microphone techniques or contact transducers, methods often more suitable for live applications, especially when utilising live processing. The need for pragmatic, musician-centric software addressing these issues is identified, along with a set of criteria relevant musicians working in the fields of live electronic performance and interactive technologies.These problems, along with proposed solutions and software tools are investigated practically in both controlled conditions and real world scenarios, and the outcomes of experimentation and testing discussed in detail. Real world testing is essential in order to ensure that any developed tools and correction procedures are robust and viable for use within the constraints of a typical concert performance of electronic music.

Finally, a generic procedure is presented for rapidly generating and applying inversions to speaker/room combinations and close audio capture using software developed to satisfy the requirements outlined earlier (The HISSTools Impulse Response Toolbox). The full paper as well as the toolbox are available for free download at http://eprints.hud.ac.uk/18549/.
