Dolby Atmos and Lossless Audio Are Not the Same Thing, and Rarely Combine
Streaming tags like 'Dolby Atmos' and 'Lossless' refer to two separate audio technologies: Atmos creates a 3D soundstage by placing sounds in space, while lossless audio preserves the full quality of a recording without the data loss found in formats like MP3 or AAC. Because Atmos typically relies on the lossy Dolby Digital Plus codec, and lossless streaming uses formats like FLAC or ALAC, most platforms can't offer both simultaneously.
