There are labels (e.g., 2L.no, trptk.com and spiritofturtle.com) that sell Auro-3D files embedded in FLAC as part of their downloadable music productions in various formats. The recorded from above acoustic reflections are mixed into 5.1, 7.1 or even 9.1 PCM streams. An Auro-3D capable device will decode the original 3D information. If there is no suitable decoder, then the original surround PCM recording will be rendered.
