For over ten years, the DIGITAL AUDIO seminar series has seen itself as an independent forum for the exchange of ideas on future topics in the field of professional audio technology. The last event took place some time ago. Due to many requests and the exciting current developments, we have decided to dedicate this seminar to the topic of surround sound again. As always, we will be focussing on the future, but this time we have placed particular emphasis on complementary acoustic demonstrations. At the seminar, away from the hustle and bustle of the trade fair, you can find out in detail about the latest developments in multi-channel sound technology, which is playing an increasingly important role in music production, theatre, sound reinforcement and broadcasting.
