A Prototypical Service for Real-Time Access to Local Context-Based Music Information

In this contribution we propose a generic service for realtime access to context-based music information such as lyrics or score data. In our web-based client-server scenario, a client application plays back a particular (waveform) audio recording. During playback, the client connects to a server which in turn identifies the particular piece of audio as well as the current playback position. Subsequently, the server delivers local, i.e., position specific, context-based information on the audio piece to the client. The client then synchronously displays the received information during acoustic playback. We demonstrate how such a service can be established using recent MIR (Music Information Retrieval) techniques such as audio identification and synchronization and present two particular application scenarios.
