A demonstration of the latest version of the TIAALS software (Tools for Interactive Aural Analysis) being developed as part of the project ‘Technology and Creativity in Electroacoustic Music’ (TaCEM) based at the Universities of Huddersfield and Durham in the UK. The software enables users to investigate electroacoustic works imaginatively using an interactive sonogram, selecting regions in time and frequency and auditioning them in real time. These can then be used to create analytical charts that are both interactive and aural. Another feature of the project is emulation software developing greater understanding of how technology influences creative processes.The overall project aims to develop greater understanding of the creative and technical processes in EA music and their interrelation to the benefit of researchers, student composers and general public. Eight case studies are being studied in depth, 3 of them works produced at IRCAM. The project is funded by the UK’s AHRC.
