We report on the practical implementation of a higher order Ambisonics decoder for irregular 3D loudspeaker layouts in the form of the open source project IDHOA. The developed decoder, which uses a nonlinear search algorithm to look for the optimal Ambisonics coefficients for each loudspeaker, has a number of features specially tailored for reproduction in practical 3D audio venues.
