In this article, an analysis of the piece Desdobramentos do contínuo for violoncello and live-electronics is addressed concerning instrumental extended techniques, electroacoustic tape sounds, real-time processing, and their interaction. This is part of a broad research about the computer-aided musical analysis of electroacoustic mu- sic. The objective of the analysis of this piece is to understand the spectral activity of the emergent sound structures, in terms of which events produce huge timbre variations, and to identify timbre subtle nuances that are not percep- tible on a first listen of the work. We conclude comparing the analyses results to the compositional hypotheses pre- sented in the initial sections.

Compositional Method

Real-time computer music is now common and ubiquitous, no longer a new or experimental practice. In its infancy, it helped to solve perceived issues with the fixity of tape pieces, a natural continuation in the practice of live electronics. However, real-time computer music did not have the same consequences as live electronic music. This situation engendered many discussions about the liveness of real-time computer music performances at the time. It is now 20 years past those first conversations, and it is important to revisit what is ‘live’ and how it applies to real-time musics. Additionally, in some ways, the language surrounding descriptions of fixed medium works, mixed works, live electronics and real-time computer music has evolved and, perhaps, even settled into conventions distinguishing musical approach and philosophies. This article first defines the language, not to proselytise, but rather to ground the argument. The conclusion asserts that liveness is a spectrum despite the fact that ‘live’ is often used categorically. Though one may have an intuitive understanding of what constitutes a ‘live’ event, this article explicitly articulates the most significantly contributive factors. The nature of real-time computer music is explored in relation to these factors of liveness. Using musical examples, this article shows that ‘real-time’ music does not guarantee a ‘live’ performance, contrary to what is typically held to be true. Instead, ‘real-time’ simply becomes a descriptor of compositional method, and any real-time work can exist along a broad range of the liveness spectrum.

Different Levels

The study of cognitive phenomena is best approached in an orderly manner. It must begin with an analysis of the function in intension at the heart of any cognitive domain (its knowledge base), then proceed to the manner in which such knowledge is put into use in real-time processing, concluding with a domain’s neural underpinnings, its development in ontogeny, etc. Such an approach to the study of cognition involves the adoption of different levels of explanation/description, as prescribed by David Marr and many others, each level requiring its own methodology and supplying its own data to be accounted for. The study of recursion in cognition is badly in need of a systematic and well-ordered approach, and this chapter lays out the blueprint to be followed in the book by focusing on a strict separation between how this notion applies in linguistic knowledge and how it manifests itself in language processing.

Reference Processing

Abstract This study examines the use of discourse-level information to create expectations about reference in real-time processing, testing whether patterns previously observed among native speakers of English generalize to nonnative speakers. Findings from a visual-world eye-tracking experiment show that native (L1; N = 53) but not nonnative (L2; N = 52) listeners’ proactive coreference expectations are modulated by grammatical aspect in transfer-of-possession events. Results from an offline judgment task show these L2 participants did not differ from L1 speakers in their interpretation of aspect marking on transfer-of-possession predicates in English, indicating it is not lack of linguistic knowledge but utilization of this knowledge in real-time processing that distinguishes the groups. English proficiency, although varying substantially within the L2 group, did not modulate L2 listeners’ use of grammatical aspect for reference processing. These findings contribute to the broader endeavor of delineating the role of prediction in human language processing in general, and in the processing of discourse-level information among L2 users in particular.

As the amount of collected spatial information (2D/3D) increases, the real-time processing of these massive data is among the urgent issues that need to be dealt with. Discretizing the physical earth into a digital gridded earth and assigning an integral computable code to each grid has become an effective way to accelerate real-time processing. Researchers have proposed optimization algorithms for spatial calculations in specific scenarios. However, a complete set of algorithms for real-time processing using grid coding is still lacking. To address this issue, a carefully designed, integral grid-coding algebraic operation framework for GeoSOT-3D (a multilayer latitude and longitude grid model) is proposed. By converting traditional floating-point calculations based on latitude and longitude into binary operations, the complexity of the algorithm is greatly reduced. We then present the detailed algorithms that were designed, including basic operations, vector operations, code conversion operations, spatial operations, metric operations, topological relation operations, and set operations. To verify the feasibility and efficiency of the above algorithms, we developed an experimental platform using C++ language (including major algorithms, and more algorithms may be expanded in the future). Then, we generated random data and conducted experiments. The experimental results show that the computing framework is feasible and can significantly improve the efficiency of spatial processing. The algebraic operation framework is expected to support large geospatial data retrieval and analysis, and experience a revival, on top of parallel and distributed computing, in an era of large geospatial data.
