Investigating computational models of perceptual attack time

The perceptual attack time (PAT) is the compensation for differing attack components of sounds, in the case of seeking a perceptually isochronous presentation of sounds. It has applications in scheduling and is related to, but not necessarily the same as, the moment of perceptual onset. This paper describes a computational investigation of PAT over a set of 25 synthesised stimuli, and a larger database of 100 sounds equally divided into synthesised and ecological. Ground truth PATs for modeling were obtained by the alternating presentation paradigm, where subjects adjusted the relative start time of a reference click and the sound to be judged. Whilst fitting experimental data from the 25 sound set was plausible, difficulties with existing models were found in the case of the larger test set. A pragmatic solution was obtained using a neural net architecture. In general, learnt schema of sound classification may be implicated in resolving the multiple detection cues evoked by complex sounds

Towards a style-specific basis for computational beat tracking

Outlined in this paper are a number of sources of evidence, from psychological, ethnomusicological and engineering grounds, to suggest that current approaches to computational beat tracking are incomplete. It is contended that the degree to which cultural knowledge, that is, the specifics of style and associated learnt representational schema, underlie the human faculty of beat tracking has been severely underestimated. Difficulties in building general beat tracking solutions, which can provide both period and phase locking across a large corpus of styles, are highlighted. It is probable that no universal beat tracking model exists which does not utilise a switching model to recognise style and context prior to application

Evaluating the Wiimote as a musical controller

The Nintendo Wiimote is growing in popularity with mu-sicians as a controller. This mode of use is an adaptationfrom its intended use as a game controller, and requiresevaluation of its functions in a musical context in orderto understand its possibilities and limits. Drawing on Hu-man Computer Interaction methodology, we assessed thecore musical applications of the Wiimote and designeda usability experiment to test them. 17 participants tookpart, performing musical tasks in four contexts: trigger-ing; precise and expressive continuous control; and ges-ture recognition. Interviews and empirical evidence wereutilised to probe the device’s limitations and its creativestrengths. This study should help potential users to planthe Wiimote’s employment in their projects, and should beuseful as a case study in HCI evaluation of musical con-trollers

Towards Machine Musicians Who Have Listened to More Music Than Us: Audio Database-led Algorithmic Criticism for Automatic Composition and Live Concert Systems

Databases of audio can form the basis for new algorithmic critic systems, applying techniques from the growing field of music information retrieval to meta-creation in algorithmic composition and interactive music systems. In this article, case studies are described where critics are derived from larger audio corpora. In the first scenario, the target music is electronic art music, and two corpuses are used to train model parameters and then compared with each other and against further controls in assessing novel electronic music composed by a separate program. In the second scenario, a “real-world” application is described, where a “jury” of three deliberately and individually biased algorithmic music critics judged the winner of a dubstep remix competition. The third scenario is a live tool for automated in-concert criticism, based on the limited situation of comparing an improvising pianists' playing to that of Keith Jarrett; the technology overlaps that described in the other systems, though now deployed in real time. Alongside description and analysis of these systems, the wider possibilities and implications are discussed

The Ubuweb Electronic Music Corpus: An MIR investigation of a historical database

A corpus of historical electronic art music is available online from the UbuWeb art resource site. Though the corpus has some flaws in its historical and cultural coverage (not least of which is an over-abundance of male composers), it provides an interesting test ground for automated electronic music analysis, and one which is available to other researchers for reproducible work. We deploy open source tools for music information retrieval; the code from this project is made freely available under the GNU GPL 3 for others to explore. Key findings include the contrasting performance of single summary statistics for works versus time series models, visualisations of trends over chronological time in audio features, the difficulty of predicting which year a given piece is from, and further illumination of the possibilities and challenges of automated music analysis

OK Computer Analysis: An Audio Corpus Study of Radiohead

The application of music information retrieval techniques in popular music studies has great promise. In the present work, a corpus of Radiohead songs across their career from 1992 to 2017 are subjected to automated audio analysis. We examine findings from a number of granularities and perspectives, including within song and between song examination of both timbral-rhythmic and harmonic features. Chronological changes include possible career spanning effects for a band's releases such as slowing tempi and reduced brightness, and the timbral markers of Radiohead's expanding approach to instrumental resources most identified with the Kid A and Amnesiac era. We conclude with a discussion highlighting some challenges for this approach, and the potential for a field of audio file based career analysis

The Impacts of Dune and The Lord of the Rings on American Culture

The middle third of the 20th century was a time of hyper-aggressive industry, invention, and progressivism. This portion of the 1900s was instrumental toward shaping modern popular culture. Two of the predominant works were J.R.R. Tolkien’s fantasy epic The Lord of the Rings and Frank Herbert’s political science fiction novel Dune. Both works inspired massive cult followings upon their release and grew in popularity largely due to the anti-war movement of the 1960s and ‘70s. They have each inspired countless works of inspiration that include some of the most popular movies and games from the 1970’s through the modern day. Their respective creations are so important because of this influence. These two masterpieces of literature have shaped our modern landscape of their respective genres. Thus, these two novels should be considered as the foundational pieces for our modern understanding of both science fiction and fantasy

The failure of consulting professionalism? A longitudinal analysis of the Institute of Management Consultants

© 2016 Taylor & Francis. Abstract: This paper offers a longitudinal analysis of the Institute of Management Consultants (IMC). Drawing on archive sources, we consider the manner in which the IMC sought to institutionalize a form of expertise specific to management consultants. Rejecting attempts to locate the boundaries of such expertise within idealized, archetypal frameworks, we analyse the IMC’s attempts to secure occupational closure in the field of consulting by means of normative, cognitive and symbolic mechanisms. While others account for the Institute’s professional project as a failure consequent upon consulting’s fragmentary knowledge base, we suggest that this project did not so much fail as drift towards another ‘hybrid’ form. In an attempt (a) to account for this shift and (b) to outline its key contours, we offer an archival analysis that explores the manner in which the Institute sought to reconcile the multiple interests and competing logics that construct professionalism within the field of consulting

Corposing a history of electronic music.

A current research project led by the author has collated nearly 2,000 historic electronic music works for the purposes of musicology; nonetheless, this collection is highly amenable to composition. New pieces can be realized by rendering a selected chronology of electronic music history. The context is a wider field of compositional endeavor in “corposition” over large audio databases especially opened up by new research in music information retrieval
