Prototyping of Ubiquitous Music Ecosystems.
In: Fifth Workshop on Ubiquitous Music (V UbiMus): From Digital Arts to Ubiquitous Music, 29 October - 1 November 2014, Vitoria, Brazil.
This paper focuses the prototyping stage of the design cycle of ubiquitous
music (ubimus) ecosystems. We present three case studies of prototype
deployments for creative musical activities. The first case exemplifies a ubimus
platform, mow3s-ecolab. The second case study makes use of the
HTML5 Web Audio library to implement a loop-based sequencer. The third prototype
- an HTML-controlled sine-wave oscillator - provides an example of using
the Chromium open-source sand-boxing technology Portable Native Client
(PNaCl) platform for audio programming on the web. This new approach involved
porting the Csound language and audio engine to the PNaCl web technology.
The Csound PNaCl environment provides programming tools for ubiquitous
audio applications that go beyond the HTML5 Web Audio framework. The
limitations and advantages of the three approaches proposed - the hybrid Java/-
- are discussed in the context of rapid prototyping of ubimus ecosystems.
