piem's homepage

Welcome to my little home in cyberspace.

My name is Paul Brossier, a.k.a. piem. I am interested in several topics, including music signal processing and open source software.

From 2002 to 2006, I prepared my PhD at the Centre for Digital Music, in the Electronic Engineering Department of Queen Mary College, University of London. My research was about Automatic Annotations of Musical Audio for Interactive Applications. The final document of my PhD thesis is available online. You may also want to check my homepage at Queen Mary.

In 2006 and 2007, I worked at the Music Technology Group, in the University Pompeu Fabra of Barcelona. I worked on several algorithms for the extraction of descriptors from music signals. For instance, I wrote the tempo extraction algorithm that is running inside Cubase 5 and some MP3 players from Yamaha.

In early 2008, I was at Fluendo, a company specialised in multimedia software development. I worked on quality assurance and architecture specific optimisation of Gstreamer's audio and video codecs, and participated to the development of Codeina, a software to automatically install missing codecs.

In 2008 and 2009, I wrote and maintained the first versions of RjDj, a crazy music software running PureData on iPhone and iPod.

For my research, I started developping aubio, a C library for audio labelling, distributed under the GPL license. This is work in progress, and is likely to stay so. Aubio is now used in several projects, including Ardour and SonicVisualiser. Find out more on the aubio homepage.

I am involved in the Debian project, a free operating system. You can have a look at the packages I maintain.
