The submission portal, which can be used to contribute to the tmt33 congress program, is open.

In our anniversary year in particular, we want the program to be extraordinarily colorful and varied! We encourage speakers from the classical sound engineering sector as well as representatives from broadcast, theater, and other live sectors, production, science, technology, and art to submit interesting contributions. Shape the tmt33 program with us!

Our exhibitors can book so-called product contributions which will be open for all visitors of the tmt33. Important: The submission of product contributions will be possible until the beginning of October. If you have any questions, please contact the or the .

A team of curators and program planners ensures that we get many exciting contributions for the Tonmeistertagung. The team specifically ask potential presenters to submit contributions. Contributions which are submitted through the call will be integrated into the appropriate sessions.

The program is therefore made up of actively invited contributions as well as those that are offered to us directly. This is how we achieve diversity! By the way: The earlier a contribution is submitted, the sooner the right environment for this contribution can be found.

The Tonmeistertagung will take place from November 12 to 15, 2025 at the CCD Düsseldorf.
