We report on the practical implementation of an Ambisonics decoder for irregular 3-D loudspeaker layouts. The developed decoder, which uses a non-linear search algorithm to look for the optimal Ambisonics coefficients for each loudspeaker, has a number of features specially tailored for reproduction in real-world 3-D audio venues (for example, special 3-D audio installations, concert halls, audiovisual installations in museums, etc.). In particular, it performs well even for highly irregular speaker arrays, giving an acceptable listening experience over a large audience area.
