Key issues for audio system configuration

Abstract
As communication technology advances, the opportunity of applying it in different contexts arises. A challenging context is music education over large distances where music education could be available for a range of people that would not be able to attain it otherwise. In order to enable a successful communication, the technical quality criteria for professional musical education over distance have to be known. This paper will review these quality criteria; what they are when focusing on the perceived audio quality and the limitations of the systems used. Also results from a paper survey conducted in a master class will be presented. The review shows that the major criteria found to be necessary for musical educations include; Audio quality of minimum 16 bit word length and a sampling frequency of 44.1 kHz (CD standard) for the music’s dynamics; minimum of two-channel stereo for accurate position of sound sources; full frequency range (20 Hz–20 kHz) for tone quality; near total synchronization of audio to video (lip-sync) as well as low delay between sender and receiver for interactivity and for rhythm practices. The major limitations are: teleconferencing systems designed for speech; inadequate echo cancellation; slow internet connections and large delay induced by the system configuration between sender and receiver. Further research is also proposed to investigate if these criteria change depending on the type of musical education performed and if haptic responses can further enhance music education over distance.

ICT as an expansion of the music teacher profession
Erik Lundström & Sture Brändström
Department of Music and Media, Luleå University of Technology
Abstract
The purpose of this article is to present earlier and ongoing research about music teachers’ use of technological tools. A certain focus will be on instrument teachers in an environment where music technology and computer communication characterizes teaching. Firstly, some examples are given to show how socio-cultural learning theories could be helpful to describe and understand the music teacher profession. After that follows a review focused on research dealing with music technology and education. The review has been divided into three different content areas: Development of software and physical interfaces, Computer based composing, and Distance music education. At the end of the paper the project Vi r Music is presented. Luleå University of Technology participates in the project 2009-2010 together with Finnish and Norwegian music institutions. Present authors are involved as researchers. The main purpose is to create an active network of distance music educators and in the long run to permanent the use of virtual instrumental pedagogy. The preliminary results point to the technology as an important and at the same time difficult factor to handle for a music teacher in action.

Good experiences on cooperation
Vi r Muscic project started 1st of February 2009. Within nine months we have had several good experiences on common virtual experiments both in teacher education and in virtual music classes. In general, Virtual meeting experiences have been positive and expected sustainable impact is seen valuable due travelling between three participating countries and five organisations was reduced dramatically compared to traditional meeting and education arrangements. It's time to present what we have achieved until now.
As the project is divided into four work packages, the first report was also structured according to them. Shortly, following results have been achieved in different WP's:
WP0, Management (Kemi-Tornio University of Applied Sciences)
- Common meetings have been organised both virtually and face-to-face. In addition, information and publicity activities and project bureaucracy are taken care within this WP.
WP1, Methods and Practices (Luleå Tekniska Universitet, Musikhögskolan i Piteå)
- Research papers on "Music Education over Distance" and "ICT as an expansion of the music teacher profession".
WP2, Teacher training (Oulun seudun ammattikorkeakoulu)
- Technical definitions on suitable equipment
- Establishing further cooperation between different music education schools
- Virtual music education pedagogy training "Basic Course of Educational Technology"
- First common international workshop 11.-12.9.2009
WP3, Virtual Classes (Särestön kamarikonsertit ry)
- "Levi Master Classes" 22.-27. June 2009, including also section when distance teaching from Finland to Japan was tested for the first time with small children playing violin.
- "Olos Virtual Classes" in autumn 2009.
- Different virtual testings have been run in addition to other virtual classes which have been orgnanised.
Samples from classes will be linked to these pages later.
