Room for Real-life Experiences

Immersive Calls

Share what happens in your life with a simple phone call. IVAS captures the 3D audio scene around you and transmits it to the listener. This is great for sharing the full immersive experience of an event or outdoor experience.

Ad-hoc Conferencing

Sometimes, you just have to do an impromptu meeting and call one or more participants on their smartphones. By positioning the telephone amidst your group, IVAS can pick up a realistic acoustic image of the surrounding people, convey and render it again at one or multiple receivers.

Multi-party Conferencing

Participating in a telephone conference with multiple callers can be an acoustic challenge. IVAS transmits voices as individual streams and spatially renders them on the receiving device – it can even match them to a video scene that is transmitted in parallel. Individual voices’ volume and position can be adapted as needed.
