In this paper, we present the HOA Library, an open source high order ambisonic spatialisation tools collection programmed in C++. We expose the objectives and characteristics of the project, which treat the potential of high order Ambisonics in a musical perspective, based on the practice and the creativity of the electronic musicians. We clarify the context of use, the choice of optimization and decoding. We review the implementations of the library in various environments, such Max, Pure Data, and Faust. We discuss the use of feedback from musicians and members of especially Max and Pure Data community. Finally, we advance the prospects of the HOA library in its current developments in three dimensions.
