Abstract

In previous papers we presented an algorithm for decoding higher order Ambisonics for irregular real-world 3D loudspeaker arrays, implemented in the form of IDHOA, an open source project. IDHOA has many features tailored for the reproduction of Ambisonics in real audio venues. In order to benchmark the performance of the decoder against other decoding solutions, we restrict the decoder to 2D layouts, and in particular to the well studied 5.1 and 7.1 surround layouts and in particular to the well studied stereo, 5.1,and 7.1 surrounds. We report on the results of the objective evaluation of the IDHOA decoder in these layouts and of the subjective evaluation in 5.1 by benchmarking IDHOA against different decoding solutions.
