How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

For network music performance (NMP), end-to-end delay is the most critical factor affecting the quality of experience (QoE) of the musicians, as longer delays prevent the musicians from synchronizing. To analyze the sensitivity of QoE to delay, we performed a controlled NMP experiment, where 11 pairs of musicians performed under a wide range of del...
This thesis investigates the temporal and spectral differences of the sound produced by the folk Greek organ bouzouki recorded using a condenser mic and electromagnet. These two techniques produce different audio results when they are used to record the sound of the bouzouki. The differences can be easily detected by the human ear. Our main goal is...
Music collaboration over the Internet, known as Network Music Performance (NMP), remains a challenge for researchers and engineers, since transmission, switching and audio processing delays hinder the synchronization of the participating musicians. Although widely available Web-based voice and video communication tools are not designed for real-tim...
Audio delay is a crucial factor in the Quality of Musicians' Experience (QoME) in Network Music Performance (NMP). Previous studies have explored the tolerance of musicians to delay and its dependence on the timbre of the instruments used and the tempo of the performance. Although their findings are intriguing, the small size of these studies makes...
In Network Music Performance (NMP), audio quality and audio delay are considered to be the most critical variables affecting the Quality of Musicians' Experience (QoME). In order to quantify the extent to which these parameters affect QoME, we executed a pilot study where eight musicians performed music in pairs in a controlled NMP setting and were...
Many existing open source systems provide support for Network Music Performance (NMP), with each one catering to a specific system and usage scenario. As our research in evaluating the Quality of Experience (QoE) of NMP systems as perceived by musicians involves widely different scenarios and requires extensive instrumentation of the platform, we b...
Considerable research has been conducted on network and system level metrics related to Network Music Performance (NMP). However, little empirical evidence is currently available to assess the actual Quality of Musician's Experience (QoME) over NMP. We propose a research framework that integrates both subjective and objective aspects of musicians'...
