Update: Designer Stijn de Vries has found an apparent logo for the Apple Music Lossless feature.

Apple Music is currently promoting a teaser for a special announcement later this week. Several different signs point to it being the addition of a lossless audio streaming option for Apple Music subscribers.

The references indicate that tracks in Apple Music will soon be available in a higher-quality lossless format.

This lines up with findings by 9to5Google in the Android Apple Music app. Apple Music for Android is readying support for two ‘lossless’ bit rates: 24-bit/48kHz and 24-bit/192kHz.

The strings in the Android app suggested the highest quality lossless stream will consume up to 36 MB of data for a single 3-minute song.

The lossless references are also next to mentions of ‘Dolby Atmos’ and ‘Dolby Audio’. It its possible that some songs will be authored in this way and enable a 3D soundstage with the Spatial Audio features of AirPods Pro and AirPods Max.

We expect Apple Music to officially announce its new hi-fi tier sometime this week. A previous report pointed to a May 18th date.
