We are working on an project called Rifff.
It's about making music that is intimately connected to a physical object. If
MP3s make music ephemeral, Rifff is a project to re-embody it.

Description:
The Viterbi Algorithm
A speech recognition algorithm searches radio waves for conversations about
money. As an ongoing investigation of the Viterbi algorithm, this project
seeks to understand the influence of a mathematical entity that is infused
throughout the fabric of contemporary society.
Two versions of the system have been testedd - one as an installation in an
old porters office in Goldsmiths University, the other as a mobile version
built into a shopping trolleyt. The porters office version displayed two very
dull looking computers one of which was a speech recognition server built
around the open source project CMUsphinx, and the other was a software
defined radio server (SDR) which was built around a hacked £10 USB TV tuner.
The speech server listened to the audio output of the SDR and if it detected
speech then it would stay on that radio station in the hope that it would
find a keyword from a list (Money, Credit, Debt, Thousand, Billion, Trillion
etc), if it didn't find any words within 20 seconds, then it would trigger
the SDRS to find another station where it would begin the process again.
