ÄÄNIAALTO is an annual festival featuring audiovisual performances, new media and sound art as well as workshops free of charge. The festival is open to everyone in the Helsinki region. Throughout its different editions, ÄÄNIAALTO has become a linking platform between emerging and established sound artists in their field.

ÄÄNIAALTO VII will be held in two parts at two locations: at Vuotalo from 2–3 September and at Vapaan Taiteen Tila from 23-24 September in the evenings.

The theme for both ÄÄNIAALTO is "ECHO-systems", to be understood as reflection of energies and pulses in an environment. Delays, different densities, changes in temperature and pressure might create illusions of ECHO-systems. Depending on the assemblages we make, we can enable interaction between each of these parts. How can we create ECHO-systems that highlight communication? How can different ECHO-systems function together enhancing sustainability?
