True Apple Spatial Audio Playback

From the very beginning, we believed there should be a way to upload and play back MP4 JOC files in MixReview, because only MP4 JOC is rendered on iOS devices the same way Apple Music delivers Apple Spatial Audio.

The Challenge

When the Spatial Audio renderer is enabled in the headphone settings, it also affects the Stereo Reference and Dolby binaural mixes, thereby altering how they sound.

How MixReview Solves This

The app automatically manages the headphone settings so that:

• Stereo Reference and Dolby Atmos binaural downmix remain untouched
• Apple Atmos (MP4 JOC files) gets "spatialized"

This ensures that your client hears exactly what you intend.

We believe this feature makes MixReview truly unique, giving mix engineers confidence in what is being reviewed.
