Made for mixing immersive formats

The S5X are optimized for binaural/immersive mix translation between headphones and speaker setup (e.g. Dolby Atmos)

1. Capture Frequency response in a certified studio

Using Kemar HATS simulator by G.R.A.S we captured frequency response of a Dolby Atmos certified studio. That was the base for the development of the prototypes that were then used in human subject A/B testing.

2. A/B human subject testing

We all perceive spatial sound differently. The A/B testing with multiple mixing engineers gave us a more in depth understanding of what is required from headphones, to translate immersive mix, between binaural and speaker setup. We applied that knowledge as weights on the original target response.

3. Create a new target curve for headphones binaural mixing

Based on our own research and plenty of articles in AES library we derived a final target curve for the immersive formats and we belive, for the future of audio. The new target curve is used as compensation in all our published reports.
