Spotify HiFi and Lossless Audio Leak Hints at Imminent Launch with FLAC Support and Spatial Sound

Spotify's long-awaited HiFi tier may finally be nearing release, according to fresh leaks from the latest desktop app update. The scoop comes from Spicetify, a command-line tool used to modify the Spotify desktop client, which surfaced multiple screenshots and strings pointing to lossless audio support in version v1.2.66.

The most eye-catching addition is a new option in the Audio Quality settings: Lossless (up to 24-bit/44.1kHz FLAC)—confirming CD-quality audio. The onboarding screens also reference lossless streaming for Premium subscribers, suggesting the feature may be tied to an upgraded subscription plan.

Beyond lossless, the leak hints at new audio enhancement features, including a mode promising a “cleaner, more natural sound” when used with supported headphones. There's also a reference to spatial audio, though no mention of standard formats like Dolby Atmos, hinting that Spotify may use proprietary tech exclusive to select headphone models.

Interestingly, there is no sign of high-resolution audio (above 44.1kHz), setting Spotify's implementation apart from competitors like Apple Music, which offers Hi-Res Lossless and Atmos for free under its standard plan.

It's important to note that these features were uncovered using the override product state function in Spicetify and aren’t currently available to users, even with the tool. What exists now are internal references—proof Spotify is actively testing HiFi internally.

Originally announced in early 2021, Spotify HiFi was expected to launch soon afterward—until Apple Music undercut the company by launching lossless and spatial audio at no additional cost. Since then, Spotify has remained silent, reportedly recalibrating its strategy. Rumors suggest the HiFi tier may still cost extra but will bundle exclusive content, including podcasts and enhanced artist features.

As of now, there's no confirmed release date. The Spotify HiFi tier could go live in a matter of days, months, or possibly not at all. But with these latest signs of life, it seems Spotify hasn’t given up on audiophiles just yet.
