The Web Audio Conference is an international conference dedicated to emerging audio-related web technologies such as Web Audio API, Web MIDI and Web RTC / WebGL. This year, from 19th to 21st of September the fourth edition was organized at the TU Berlin gathering web developers, music technologists, computer musicians, application designers, researchers, and people involved in web standards.




Oscar Mayor from Voctro Labs presented a demo of the research on audio transformation and synthesis technologies being developed during the TROMPA project:

    VOICEFUL: Voice Analysis, Transformation and Synthesis on the Web
    Oscar Mayor, Jordi Janer, Hector Parra and Álvaro Sarasúa


During the hands-on demo, the attendees were able to experience themselves with some web prototypes able to analyze their voice and extract meaningful musical information, transform the characteristics of their vocal timbre in real-time or synthesize a musical score changing the lyrics of it. All these technologies are available in the Voiceful Toolkit

The feedback from the audience was quite satisfactory and many people was asking about the availability of these tools on the web to be used by anyone for instance for improving musical skills.
