Digitization of Analog Phonic Archives in a University Lab: A Report on a Young Apprenticeship Initiative

[EN] This paper discusses an initiative of young apprenticeship for Italian secondary school students, carried out in a university lab rather than in a traditional working environment. The practical aim of the proposal was to make participants digitize phonic archives on analog media, such as open-reel tapes and vinyl records. The goal of the paper is to provide a comprehensive review of this experience, highlighting the educational value of young apprenticeship activities in an academic context and critically analyzing its strengths and weaknesses. The work will also discuss the feedback received from students.http://ocs.editorial.upv.es/index.php/HEAD/HEAD18Ludovico, LA.; Presti, G. (2018).

MIDI. Una guida al protocollo, alle estensioni e alla programmazione

illustratorIl testo mira ad affrontare l’intero ecosistema MIDI dal punto di vista dei protocolli, formati, dispositivi hardware e software e librerie di supporto alla programmazione. Il volume si articola in due parti, la prima delle quali è dedicata alla descrizione del protocollo originario e delle sue estensioni, fino alla recentissima introduzione del MIDI 2.0 (febbraio 2020). La seconda parte affronta il tema della programmazione di applicativi software secondo diverse filosofie, che spaziano dall’uso di linguaggi multi-piattaforma “tradizionali” (Java) all’adozione della Web MIDI API per la programmazione web

Sound and the City: Multi-Layer Representation and Navigation of Audio Scenarios

IEEE 1599-2008 is an XML-based standard originally intended for the multi-layer representation of music information. Nevertheless, it is versatile enough to describe also information different from traditional scores written according to the Common Western Notation (CWN) rules. This paper will discuss the application of IEEE 1599-2008 to the audio description of paths and scenarios from the urban life or other landscapes. The standard we adopt allows the multilayer integration of textual, symbolical, structural, graphical, audio and video contents within a unique synchronized environment. Besides, for each kind of media, a number of digital objects is supported. As a consequence, thanks to the features of the format the produced description will be more than a mere audio track, a slideshow made of sonified static images or a movie. Finally, an ad hoc evolution of a standard viewer for IEEE 1599 documents will be presented, in order to enjoy the results of our efforts

Musica Sull\u27Acqua : A motion tracking based sonification of an aquarium in real time

This paper presents a temporary multimedia installation set up at the Civic Aquarium of Milan. Thanks to four web cameras located in front of the tropical fishpond, fish are tracked and their movements are used to control a number of music-related parameters in real time. In order to process multiple video streams, the open-source programming language Processing has been employed. Then, the sonification is implemented by a Pure Data patch. The communication among the parts of the system has been realized through Open Sound Control (OSC) messages. This paper describes the key concepts, the musical idea, the design phase and the implementation of this installation, discussing also the major critical aspects

Algorithms for an Automatic Transcription of Live Music Performances into Symbolic Format

This paper addresses the problem of the real-time automatic transcription of a live music performance into a symbolic format. The source data are given by any music instrument or other device able to communicate through a performance protocol. During a performance, music events are parsed and their parameters are evaluated thanks to rhythm and pitch detection algorithms. The final step is the creation of a well-formed XML document, validated against the new international standard known as IEEE 1599. This work will shortly describe both the software environment and the XML format, but the main analysis will involve the real-time recognition of music events. Finally, a case study will be presented: PureMX, a set of Pure Data externals, able to perform the automatic transcription of MIDI events

Wii Remote-based Collaborative Interfaces for Music

Wii Remote is the main controller for Nintendo\u27s Wii con- sole. Thanks to the use of accelerometer and optical sensor technology, it presents motion sensing capability, which implies gesture recognition and intuitive pointing. Such a controller is user-friendly, inexpensive and easily available, due to growing Wii console\u27s popularity. These features make Wii Remote a good device to create and manipulate both music and audio in a home entertainment environment. In this paper, the most interesting characteristics of the controller will be reviewed. A case study will be presented, namely the creation of a virtual music instrument to be controlled in a collaborative way through a set of Wii Remotes

Head in space : A head-tracking based binaural spatialization system

This paper discusses a system capable of detecting the position of the listener through a head-tracking system and rendering a 3D audio environment by binaural spatialization. Head tracking is performed through face recognition algorithms which use a standard webcam, and the result is presented over headphones, like in other typical binaural applications. With this system users can choose an audio file to play, provide a virtual position for the source in an euclidean space, and then listen to the sound as if it is coming from that position. If they move their head, the signal provided by the system changes accordingly in real-time, thus providing a realistic effect

PureMX: Automatic transcription of MIDI live music performances into XML format

This paper addresses the problem of the real-time automatic transcription of a live music performance into a symbolic format based on XML. The source data are given by any music instrument or other device able to communicate with Pure Data by MIDI. Pure Data is a free, multi-platform, real-time programming environment for graphical, audio, and video processing. During a performance, music events are parsed and their parameters are evaluated thanks to rhythm and pitch detection algorithms. The final step is the creation of a well-formed XML document, validated against the new international standard known as IEEE 1599. This work will shortly describe both the software environment and the XML format, but the main analysis will involve the realtime recognition of music events. Finally, a case study will be presented: PureMX, an application able to perform such an automatic transcription

Music-Related Media-Contents Synchronization over theWeb: the IEEE 1599 Initiative

IEEE 1599 is an international standard originally conceived for music, which aims at providing a comprehensive description of the media contents related to a music piece within a multi-layer and synchronized environment. A number of o_- line and stand-alone software prototypes has been realized after its standardization, occurred in 2008. Recently, thanks to some technological advances (e.g. the release of HTML5), the engine of the IEEE 1599 parser has been ported on the Web. Some non-trivial problems have been solved, e.g. the management of multiple simultaneous media streams in a client-server architecture. After providing an overview of the IEEE 1599 standard, this article presents a survey of the recent initiatives regarding audio-driven synchronization over the Web

Integration of Audio Resources into a Digital Library: The BEIC Case Study

The focus of this paper is on the integration of audio resources with other content types in digital libraries. As a case study, we will present the most recent initiative of the Biblioteca Europea di Informazione e Cultura (BEIC), an Italian institution that pursues educational and instructional goals through the realization and management of a multimedia, free access, open shelf library. A new audio section will be added to the already-existing digital archive, allowing users to listen to about 1000 classical recordings in a multi-platform and cross-browser manner. This experience involves a number of heterogeneous fields, ranging from musicology to computer programming, from cataloging to digitization and archiving. In this paper, we will apply a bottom-up technique in order to provide a generalization of the specific case study, thus suggesting a methodological approach for similar initiatives
