- Since 2007, ethnomusicologist and engineers have joint their effort to develop a scalable and collaborative web platform for management and access to large digital sound archives. This platform has been deployed since 2011 and hold the archives of the \emph{Center for Research in Ethnomusicology}, which is the most important collection in Europe.\r
- This web platform is based on Telemeta, an open-source web audio framework dedicated to digital sound archives secure storing, indexing and publishing. It focuses on the enhanced and collaborative user-experience in accessing audio items and their associated metadata and on the possibility for the expert users to further enrich those metadata.\r

\r
Telemeta architecture relies on \emph{TimeSide}, an open audio processing framework written in Python which provides decoding, encoding and streaming methods for various formats together with a smart embeddable HTML audio player. TimeSide also includes a set of audio analysis plugins and additionally wraps several audio features extraction libraries to provide automatic annotation, segmentation and musicological analysis.\r
\r
In social sciences like anthropology and linguistics, researchers have to work on multiple types of multimedia documents such as photos, videos, sound recordings or databases. The need to easily access, visualize and annotate such materials can be problematic given their diverse formats, sources and given their chronological nature.\r
%With this in mind, some laboratories\footnote{The Research Center on Ethnomusicology (CREM), the Musical Acoustics Laboratory (LAM, UMR 7190) and the sound archives of the Mediterranean House of Human Sciences (MMHS)} involved in ethnomusicological research have been working together on that issue.\r
\r
- In the context of ethnomusicological research, the Research Center on Ethnomusicology (CREM) and Parisson, a company specialized in the management of large audio databases, have been developing an innovative, collaborative and interdisciplinary open-source web-based multimedia platform since 2007. \r

-This platform, Telemeta is designed to fit the professional requirements from both sound archivists and researchers in ethnomusicology. The first prototype of this platform has been online since 2011 and is now fully operational and used on a daily basis for ethnomusicological studies. A description of theses archives and some use cases are given in Section~\ref{sec:archives-CREM}.\r

\section{The Telemeta platform}\label{sec:Telemeta}\r
\subsection{Web audio content management features and architecture}\r
- The primary purpose of the project is to provide the ethnomusicological communities with a scalable system to access, preserve and share audio research materials together with their associated metadata, as these data provide key information on the context and significance of the recording. Telemeta\footnote{http://telemeta.org}, as a free and open source\footnote{Telemeta code is available under the CeCILL Free Software License Agreement \texttt{http://cecill.info/licences/Licence\_CeCILL\_V2-en.html}}, is a unique scalable web audio platform for backuping, indexing, transcoding, analyzing, sharing and visualizing any digital audio or video file in accordance with open web standards.\r

+The time-based nature of such audio-visual materials and some associated metadata as annotations raises issues of access and visualization at a large scales. Easy and on demand access to these data, as you listen to the recording, represents a significant improvement.\r

+ \item On the fly audio analyzing, transcoding and metadata\r
+ embedding in various formats\r
+ \item Social editing with semantic ontologies, smart workflows,\r
+ realtime tools, human or automatic annotations and\r
+ segmentations\r

\subsection{Metadata}\label{sec:metadata}\r
In addition to the audio data, an efficient and dynamic management of the associated metadata is also required. Consulting metadata provide both an exhaustive access to valuable information about the source of the data and to the related work of peer researchers. \r
Dynamically handling metadata in a collaborative manner optimises the continuous process of knowledge gathering and enrichment of the materials in the database. \r
It also allows researchers to exchange data online with communities producing their music in their home countries.\r

\r
Further works on the user interface will enhance the visualization experience with time and frequency zooming capabilities and will thus improve the accuracy and the quality of time-segment base annotations.\r
