Listening to the Mind Listening

The following explains what mappings have been chosen for a sonification of several data channels from set containing a recording of the neural activity of a person listening to a piece of music. This piece, and also the sonification, is exactly 300 seconds long. My aim is to provide a sonification/composition that can be created in (near) real-time and takes its title literally. This is done by loading the data into a software program - Artwonk by John Dunn and performing all mappings in real-time. The results are, again in real-time, sent to several software samplers that `play' the music. Software samplers were chosen because of their low CPU cycle consumption. If the number of sonification data streams is low (3 to 5) near real-time sonification is certainly possible. REDUCTION The first thing that was done was that the amount of data was reduced by a factor of 10. The original data format was sampled at 500Hz, which is a sample every 2 milliseconds. This is too fast a rate t...
