The 142nd Audio Engineering Society International Convention is now another one for the books. Held May 20 to 23 at the Maritim Hotel in the heart of Berlin near Potzdamer Platz, the venue was a larger and more convenient location than when the Society last visited Berlin in 2014. AES Berlin 2017 featured the traditional strengths of these annual gatherings: intensive and expansive technical program offerings; variety, with session topics that span the gamut of professional audio; engaged and energetic students; and an exhibition floor with the latest audio hardware and software on display.
