Immersive Check vs QUARK Play

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.

QUARK Play easily transforms up to four iOS devices into a wireless, quadraphonic sound system. Place iPhones, iPads, and/or Macs around the space (or connect them to bluetooth speakers), hit play on the host device, and build a true, immersive surround sound environment anywhere. The Quadraphonic Universally Accessible Resource Kit (QUARK) is open source software used in Digital Audio Workstations (DAWs) and similar platforms to encode four channels of discrete audio into two channel (standard stereo) audio, then back to four channels again. This allows for the distribution of four-channel spatial recordings via widely accessible two-channel formats such as vinyl, cassette, and radio, as well as digital platforms such as YouTube, Spotify, and Qobuz. QUARK is made possible by dublab & the National Endowment for the Arts.
