As a follow-up to the Historic Program on “Perceptual Audio Coding—The First 20 Years” that took place during the 125th AES Convention in San Francisco (2008), this workshop focuses on how new trends are likely to reshape the meaning and scope of Perceptual Audio Coding (PAC) during the next two decades. A panel of experts will discuss current issues and will highlight consistent signs existing today and that suggest significant shifts and gains. In particular: how did we get here and what are the main tools of the trade? What new paradigms and divide-and-conquer approaches will shape the future of PAC? Will PAC be driven by auditory scene analysis? Will PAC move from a set of techniques that perform fairly well with general audio, to a large set of compression techniques highly tuned to specific auditory objects (or audio objects/sources) and thus highly efficient? How efficiently can we compress speech or singing and what new advances are likely to take place? How efficiently can we compress individual instrument sounds?
