Daala (Core Author)

Daala is the code-name for a new video compression technology. The effort is a collaboration between Mozilla Foundation, Xiph.Org Foundation and other contributors. The goal of the project is to provide a free to implement, use and distribute digital media format and reference implementation with technical performance superior to h.265.

Opus (Core Author)

Opus is a totally open, royalty-free, highly versatile audio codec. Opus is unmatched for interactive speech and music transmission over the Internet, but is also intended for storage and streaming applications. It is standardized by the Internet Engineering Task Force (IETF) as RFC 6716 which incorporated technology from Skype's SILK codec and Xiph.Org's CELT codec.

Speex (Project lead, main author)

Speex is an open source (BSD-licensed) audio codec that is optimised for voice. Unlike other codecs like MP3 and Ogg Vorbis, Speex is specially designed for compressing voice at low bit-rates for applications such as voice over IP (VoIP). It uses the Ogg container format and is meant to be complementary to the Vorbis codec.

FlowDesigner (Core developer)

FlowDesigner is a free (LGPL) "data flow oriented" development environment. It can be use to build complex applications by combining small, reusable building blocks. In some way, it has similarities with Simulink and LabView, although it is not designed (and far) to be a "clone" of any of them. So far, it has been used for tasks like signal and speech processing, neural networks, vector quantization, fuzzy logic and robotics.

ManyEars (Main author)

ManyEars provides FlowDesigner building-blocks for microphone array processing. This includes sound source localisation, tracking and separation.
