4 vacantes disponibles en el IRCAM - Desarrolladores e Investigadores - Urgente



INTRODUCTION TO IRCAM
IRCAM is a leading non-profit organization dedicated to musical production, R&D 
and education in acoustics and music. The organization is located in the center 
of Paris (France), next to the Pompidou Center. It hosts composers, researchers 
and studen from many countries cooperating in contemporary music production, 
scientific and applied research. The main topics addressed its R&D Department 
are acoustics, psychoacoustics, audio synthesis and processing, computer-aided 
composition, user interfaces, real-time systems, sound design, human cognition, 
musicology.

Detailed activities of IRCAM and its groups are presented on our WWW server:

JOB TITLE : Software developer in signal processing applied to music

JOB DESCRIPTION : Full-time position for a software developer (4 months). The 
aim is to develop a prototype application, in collaboration with an industrial 
partner, based of audio processing of singing. The main specific aims are: - 
The integration of C/C++ software libraries using an API provided by the 
industrial partner under Windows. - The creation of simple algorithms and 
adjustment of settings for the specific needs of the applications. - Tests and 
validation of the application

 REQUIRED EXPERIENCE :
 •     Solid background in C/C++
 •     Strong familiarity with OSX, Windows and Linux
 •     Musical knowledge and/or practices of digital audio technologies
 •     Familiar with audio signal processing
 •     Good communication and collaborative skills

 AVAILABILITY : The position is for October 1st to January 2012 in the 
Real-time Musical Interaction team of the R&D Department at IRCAM. For foreign 
candidates, to be able to begin at once, you will have to have the necessary 
working papers to be able to work in France. Extensions of the contract may be 
proposed according to the result of this first development phase.

 DURATION : 4 months, with possible extension according to the results of this 
first development phase

 SALARY : According to background and experience.

 LOCATION : IRCAM is located in the center of Paris (FRANCE), and next to the 
Pompidou Museum for Modern Art. 1 Place Igor Stravinsky, 75004 PARIS, FRANCE

 TO APPLY : Send your application letter with a resume including your 
qualifications and pertinent information by email to : 
[email protected], Object : Voice developer position



 JOB TITLE: Researcher and Developer for the Audio2Note (A2N) Project

 A full time researcher position is immediately available in the 
analysis/synthesis team of IRCAM.

 The Analysis/Synthesis team is researching and developing new and advanced 
algorithms for sound signal anal synthesis and transformation. The A2N project 
aims to establish signal processing libraries for accessing individual note 
polyphonic possibly multichannel audio signals. The algorithm is based on a C++ 
implémentation of an algorithm for mul fundamental frequency estimation that 
has been developed previously in the Analysis/Synthesis team. The objective of 
position is to finalize, evaluate and optimize the current implementation and 
to conduct research and development of the library for a number of applications 
in the context of different software environments.

 RESEARCH AND DEVELOPMENT TASKS: The candidate will perform the following 
tasks: o conduct research into algorithmic improvements of the existing      
algorithms o conduct research into adaptations as well as extensions of the 
existing    algorithms for new applications. o supervise students working on 
problems related to the A2N project o evaluation of existing and newly 
developed algorithms o design, implement and continually improve the library 
and the corresponding API for integration into different soft applications. o 
communicate with other developers to ensure a smooth integration of the library 
in existing software environments. o testing of the library. o create and 
distribute demo packages and beta releases for testing purposes. o handling of 
user feedback. o prepare software releases.

 REQUIRED EXPERIENCE AND COMPETENCE:
 o Excellent knowledge of digital audio signal processing algorithms
 o Several years of experience with signal processing algorithms covering the 
fields: polyphonic fundamental freque estimation, spectral masking, signal 
separation, spectral domain representations, sinusoidal models.
 o Excellent knowledge and multiple years of experience with the MATLAB 
programming environment.
 o Good knowledge and experience of C++ and C programming language.
 o Experience with STL.
 o Interest for music. o High productivity, methodical and autonomous work, 
creativity, good communication skills, and excellent programming style.

 AVAILABILITY: The position is available in the "Analysis/Synthesis" team in 
the R&D department starting as soon as possible.

 DURATION The initial contract is for 6-8 months, a prolongation of the 
contract is intended. It will depend on the results obtained during initial 
working period.

 SALARY: According to background and experience.

 TO APPLY: - Please send your resume with qualifications and other pertinent 
information preferably by email to:
 [email protected] (Axel Roebel, Head of the Analysis/Synthesis team)
 or by fax at: (33 1) 44 78 15 40, to Axel Roebel
 or by surface mail to: Axel Roebel, IRCAM, 1 Place Stravinsky, 75004 Paris.



 JOB TITLE: Post-doc - Hierarchical object based unsupervised learning for 
machine listening

 RECRUITEMENT DATE: as soon as possible

 DURATION: 8 months

 DESCRIPTION OF THE PROJECT: Despite recent advances in machine perception, 
largely due to advances in machine learning techniques, much remains to be d in 
the field of Computational Auditory Scene Analysis (CASA), which aims at 
bringing mechanisms of the human auditory syste machine perception by 
automatically understanding an auditory scene through identification and 
description of sound sour CASA is today an active research field at the 
intersection of audio processing and machine learning.
 The prospective researcher will study with the supervisor the potential of 
novel unsupervised learning techniques to tackle r world CASA problems as part 
of an ANR project entitled Hierarchical Object based Unsupervised Learning 
(HOULE). In this proj our approach tries to benefit from the schemes of 
existing CASA approaches: first, to tackle the intrinsic hierarchical structur 
audio scenes (atoms gather into sound objects that are instances of classes 
such as "Piano C4 notes", itself an example of "Pi note"); and second, to 
benefit from the redundancy present at many levels of the hierarchy. This 
redundancy will potentially let identify templates upon which to build a robust 
and meaningful representation.

 EXPECTED PROFILE: Candidates must hold or be about to defend a PhD in audio 
signal processing and/or statistical machine learning. Proficient co in Matlab 
and C++ is necessary.

 SALARY: depending on experience and education

 APPLICATION: Applications including a resume must be sent before September 9, 
2011 preferably by email to Mathieu Lagrange : [email protected]
