SpatDIF

h1. Introduction

Many spatialization algorithms use a self-contained syntax and storage-format, wherein control messages (e.g. trajectories to move a sound virtually) programmed for one application are incompatible with any other implementation.

This lack of a standardization complicates the portability of compositions and requires manual synchronization and conversion of control data - a time consuming affair. Incompatible data formats also prevent collaboration between researchers and institutions.

The general idea is to development of a format to describe, store and share spatial audio scenes across 2D/3D audio applications and concert venues.

Therefore we call for a collaborative developing of *SpatDIF - a format to describe spatial audio information in a structured way* to support real-time and non-real-time applications.

h1. Goals

*Platform independence:* Ideally any 3D audio rendering algorithm on any computer platform should technically be able to understand SpatDIF;

*Easily understandable syntax:* to prevent misunderstandings when stored data are shared;

*Extendability:* Easy adding of descriptors to extend the specification especially as long as SpatDIF is in development;

*Free and open source:* to increase the acceptance and widespread usage of this new format;

*Easy to connect:* with interfaces, controllers and sensors for real-time control of spatialization;

*Use of existing standards:* to focus on conceptual rather than technical development.
