A method for recreating complex soundscapes for tasks related to audio quality evaluation is presented. This approach uses an ambisonics-inspired basis for recreating dynamic noise in a system compatible with ETSI standard EG 202 396-1 for background noise reproduction. Recordings were captured with a spherical 32-microphone array and processed to match the two-dimensional four-loudspeaker array by creating four directional beams, each feeding an individual channel. As a result, a spatial background noise ambience is recreated, preserving the transient characteristics of the original recording.
