The Apple Music app on Android seems to have revealed new details on the company's rumoured lossless offering. 9to5Google found code snippets referring to two different tires of high-fidelity audio—"Lossless" and "High-res Lossless." The former will supposedly have songs encoded in Apple's ALAC codec up to 48kHz, while the latter improves the quality up to 192kHz.
Dolby Atmos or Dolby Audio wasn't spotted in the code for Apple Music 3.6, but it was referenced by the company in iOS 14.6 beta 1 before it was removed from beta 2.
