We present the WASABI 1 Song Corpus, a large corpus of songs enriched with metadata extracted from music databases on the Web, and resulting from the processing of song lyrics and from audio analysis. More specifically, given that lyrics encode an important part of the semantics of a song, we focus here on the description of the methods we...

In this paper, we detail our on-going browser-based re-creation of a famous tube guitar amplifier and describe the JavaScript implementation we have been developing using the WebAudio API. The tricky part of such an amplifier is the power stage (Power Amp) which contains a parametric negative feedback loop. We show the limits of the high-level...

In this paper are exposed our latest experiments with the WebAudio API to design different types of gears for guitarists: real-time simulations of tube guitars amplifiers, fx pedals, and their integration in a virtual pedal board. We have studied different real guitar tube amps and created an interactive Web application for experimenting,...

This paper presents a tube guitar amplifier simulation made with the WebAudio API, that reproduces the main parts of the Marshall JCM 800 amplifier schematics. Each stage of the real amp has been recreated (preamp, tone stack, reverb, power amp and speaker simulation, and we added an extra multiband EQ). The " classic rock " amp simulation we...

We propose to present a tube guitar amplifier simulation we've been designing using the Web Audio API with the aim to faithfully reproduce the main parts of the Marshall JCM 800 amplifier schematics. Each stage of the real amp has been recreated (preamp, tone stack, reverb, power amp and speaker simulation). We've also added an extra multiband...

The ANR project WASAB will last 42 months and consists in developing a 2 million songs database with interactive WebAudio enhanced client applications 1. Client applications target composers, music schools, sound engineering schools, musicologists, music streaming services and journalists. In this paper, we present a virtual pedal board (a set...

Wikis are social web sites enabling a potentially large number of participants to modify any page or create a new page using their web browser. As they grow, wikis may suffer from a number of problems (anarchical structure, aging navigation paths, etc.). We believe that semantic wikis can improve navigation and search. In SweetWiki we...

Since 2012 and the advent of the Web Audio API, the development of computer music applications within web browsers has become feasible. Recent improvements in this API and other advancements in web browser technology have significantly expanded the possibilities for new developments. Thanks to the WebAssembly and AudioWorklets APIs, code...

In 2016, we pioneered an approach to reproduce and experiment with Web-based simulations of classical tube guitar amplifiers, initially the Marshall JCM800 used by many famous musicians (e.g. AC/DC). Our implementations run within standalone Web browsers. The different stages of the amps are perceptually approximated using simple tools from the...

This article presents WAM Studio, an opensource digital audio workstation (DAW) that leverages W3C standards such as Web Audio, Web MIDI, Web Assembly, and Web Components, as well as the Web Audio Modules (WAM) plugin standard (aka "VSTs for the Web"). WAM-Studio has been developed as an open-source demonstrator of Web standards and contains...

This article presents WAM-Studio, an opensource digital audio workstation (DAW) that leverages W3C standards such as Web Audio, Web MIDI, Web Assembly, and Web Components, as well as the Web Audio Modules (WAM) plugin standard (aka "VSTs for the Web"). Developed since 2022, WAM-Studio and its fork Attune have already been the subject of several...

In this paper we propose an approach to manage access rights in a content management systems which relies on semantic web models and technologies. We present the AMO ontology which consists (1) in a set of classes and properties dedicated to the annotation of resources whose access should be controlled and (2) in a base of inference rules...

This paper presents WAM Studio, an open source, online Digital Audio Workstation (DAW) that takes advantages of several W3C Web APIs, such as Web Audio, Web Assembly, Web Components, Web Midi, Media Devices etc. It also uses the Web Audio Modules proposal that has been designed to facilitate the development of inter-operable audio plugins...

This article introduces WAM Studio, an open-source online digital audio workstation (DAW) that takes advantage of several W3C APIs and standard technologies, such as Web Audio, WebAssembly, Web Components, Web Midi, Media Devices, etc. WAM Studio is also based on the Web Audio Modules (WAM) standard, which was designed to facilitate the...

This paper presents our approach to collaborative and semi- automated semantic structuring of folksonomies. Tags freely provided by users of online communities are not semanti- cally linked, and this hinders significantly the potentials for browsing and exploring these data. We propose a socio- technical system combining automatic handlings of...
