The demand for the production, distribution and playback of audio content in surround or immersive multichannel formats and flexible playback setups has continued to grow in the cinema, broadcast and music industries. This trend motivates the continued development of multichannel audio signal processing methods for the conversion of recordings between different multichannel and spatial audio formats or layouts, including down- or up-mixing. These operations leverage a well researched frequency-domain processing framework nowadays commonly referred to as parametric spatial audio signal processing, to solve challenges including the primary-ambient decomposition of audio recordings. Bringing ML/AI techniques to bear in the development of novel spatial audio analysis/synthesis methods can unlock practical applications with transformative impact. In this workshop, we will review and discuss the fundamentals and recent progress in these methods.
