Every year since 2004, the c/o pop Festival has transformed Cologne into an urban pop culture mecca. With hundreds of program items - from concerts in unusual locations to surprising experience formats - the streets and stages in Cologne-Ehrenfeld are transformed into a pulsating festival center - and at the same time the c/o pop Convention offers a central meeting place for the music industry - with space for creative exchange at eye level. What makes c/o pop special? The tireless desire to discover new things and experience unforgettable highlights together. Artists such as Moderat, Giant Rooks, Ski Aggu, Bilderbuch and AnnenMayKantereit were on stage here long before they had their big breakthrough. Instead of big headliners, the festival deliberately focuses on diversity and brings current pop culture right into the heart of the city. Open spaces, DIY events, performances and a lively market in Ehrenfeld make c/o pop special. With a clear focus on Diversity, Equality & Inclusion (DEI), it promotes FLINTA* and queer artists as well as other underrepresented groups. Everyone is welcome here! At the same time, the c/o pop Convention offers practical keynotes, inspiring talks and workshops that deal with the current challenges and future issues of the music industry. During the day, it is a place for valuable impulses and networking, before celebrating the diversity of pop culture together in the evening.

This app allows you to easily switch and compare Dolby Atmos mixes like Spatial Audio (Apple Music) and Binaural with the Stereo format. This makes it easier to give feedback, suggestions or approval before release. This app is for headphones only, as it's the easiest way to hear and compare the different Dolby Atmos versions without expensive studio equipment. Immersive Check works with any headphones connected to the iPhone. (Of course, Apple-specific applications such as head tracking etc. only work with Apple headphones). Immersive Check works very simply. Once the final mixes from any Dolby Atmos studio have been uploaded to the server, you get access with a personal code and can listen to the different versions. There is no download option. It is also possible to adjust the volume of the different versions, The respective volumes can be entered in an info field by the studio for the consumer so that they are played at the same volume.

Verdict
The clearest difference is update cadence: Immersive Check at every 3 weeks against c/o pop's every 6 months. Immersive Check also leads on iOS requirement (12.1 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.
