A compositional approach to analysis re-synthesis
This report summarises the work achieved in the framework of a composer in research project in the IMTR team at IRCAM. In this project we have experimented with different realtime processing techniques for the analysis, transformation, and resynthesis of particular morphological aspects of live performed voice and instrumental sounds. Based on segment-wise sound descriptions, the developed tools allow for re-orchestrating and re-organising particular morphological aspects of the live performer's sound using concatenative synthesis of pre-analysed sound materials driven by the real-time analysis. The relationship between the morphology of live performance and the synthesised sound materials is controlled by a set of compositional tools manipulating the extracted sound descriptions in real-time.
First Steps in Relaxed Real-Time Typo-Morphological Audio Analysis/Synthesis
This paper describes a real-time audio analysis/resynthesis system that we developed for a music piece for ensemble and electronics. The system combines real-time audio analysis and concatenative synthesis based on the segmentation of sound streams into constituting segments and the description of segments by an efficient set of descriptors adapted to the given musical context. The system has been implemented in Max/MSP using the FTM & Co and MuBu libraries and successfully employed in the production and performance of the piece. As more and more research in the domain of music information retrieval, we use the term of typo-morhpology to designate the description of sounds by morphologic criteria including the temporal evolution of sound features that also can provide pertinent means for the classification of sounds. Although, the article mainly insists on the technical aspects of the work, it occasionally contextualizes the different technical choices regarding particular musical aspects.
Arc flash hazard assessment in the mining industry
When it comes to electrical safety in the workplace, arc flash has become the most prominent topic over the past decade. The Occupational Safety and Health Administration (OSHA, including state chapters) is the only government body that recognizes NFPA-70E, Standard for Electrical Safety in the Workplace. However, OSHA does not have jurisdiction in mining operations. Electrical safety for the metal and nonmetal surface mining industry is covered by the Code of Federal Regulations (CFR) Title 30, Part 56, Subpart K (Electricity). The Mine Safety and Health Administration (MSHA) is responsible for enforcing electrical safety in mining operations. CFR Title 30 does not reference personal protective equipment (PPE) to protect electrical workers against arc flash hazards. This paper provides maintenance and safety personnel in surface Metal/Nonmetal mining operations with a step by step guide to implementing an electrical safety program that meets the requirements of MSHA, CFR Title 30 and NFPA-70E.
