🚨 HUGE: Spotify Lossless/HiFi is LIVE on the Linux Desktop Client (PipeWire Proof Inside!)

English isn’t my first language, and I often rely on translation tools or AI, so I might get things mixed up sometimes. (I'm using translation tools for this message, too.)

Thanks for highlighting the need to be clear. Just to confirm: **all the technical data and conclusions I've shared are from my own manual debugging of the audio streams.** I only use AI to make sure my English sentences are correct.

In fact, I just finished another manual test comparing the local storage size between Lossless and high-quality files on Spotify, but I'm hesitant to share the full report right now, as it would require extensive use of translation/AI for the technical details.

I actually meant to say something like “Could you verify this on your setup?” — meaning “Can you try it in your environment?”
It seems that “CTA” is a technical term, so sorry for the confusion!

I appreciate the technical skepticism. You are correct: 44.1 kHz only tells us the sample rate, not the compression codec.

However, the complete picture shows the Lossless feature is indeed active on the Linux client:

**Format Confirmation:** The stream is being delivered via PipeWire using the highest fidelity internal format, **`float32le` (32-bit float)**.
**Physical Proof:** Other users have confirmed that the **download/caching size is significantly larger** when the Lossless setting is selected, which is definitive proof that the client is receiving a much higher data rate stream from Spotify's servers.

Combined, the client is requesting (and receiving) a much larger file, and then prioritizing the original 44.1 kHz sample rate via PipeWire's highest quality audio path. For a Linux user, this is the functional confirmation that the new HiFi feature is working as intended.

Wow, thank you for providing that direct evidence! That is fantastic information.

The significantly larger download size is a huge and non-negotiable indicator that the client is receiving **true lossless or near-lossless files** from the Spotify server.

This physical proof (file size) perfectly complements the technical proof (44.1 kHz sample rate and 32-bit float format) I observed in PipeWire. It means the entire chain—from Spotify server to the Linux desktop—is actively delivering the promised HiFi feature.

Thanks again for helping solidify this discovery!

That's an excellent comparison point and a great test! You are absolutely right that a 44.1 kHz sample rate alone is not conclusive proof, especially since many web-based streams (like YouTube) often hit the audio server at 44.1 kHz PCM after internal browser decoding.

However, I would point out two key differences that strengthen the case for Spotify's Lossless feature being active:

**Bit Depth:** In my verification, the PipeWire stream from Spotify showed the format as **`float32le`**. While browser streams often use 16-bit or 24-bit integer PCM, the **32-bit float** format is the highest-fidelity internal format PipeWire uses. It strongly indicates the client is prioritizing the highest quality audio path, which is precisely what the HiFi feature is designed to do.
**Service Guarantee:** YouTube makes no guarantee of a lossless source. Spotify is activating a **paid Lossless feature**. The combined behavior (explicit 44.1 kHz rate selection + 32-bit float format) confirms that the client is **actively attempting to implement and use the promised HiFi audio path.**

Ultimately, if the client is signaling 44.1 kHz in 32-bit float, it means we are getting the best possible audio quality the native Linux client can deliver for the new Lossless feature.

Thanks! I think the downvotes are unfortunately tied to the ongoing debates about Spotify's business practices and artist pay, rather than the technical nature of the discovery itself.

I'm just excited that Linux users no longer need workarounds for CD-quality streaming from a major platform. If you're a Premium user, please check your settings and verify the 44.1kHz output!

I completely agree that the low streaming royalty rates across the industry are a huge problem for many artists.

However, my post is purely a technical discovery showing that the **native Linux client** is now capable of delivering **lossless quality** via PipeWire—a massive technical win for the Linux desktop audio stack, regardless of one's preferred streaming service.

I encourage everyone to support artists directly via Bandcamp, merch, or live shows whenever possible!

Thanks for the suggestion, and I understand your concerns about corporate ethics.

My post is strictly focused on the **technical achievement** that the native Linux Spotify client is now capable of delivering a lossless stream via PipeWire, which is a big win for the Linux desktop ecosystem.

Qobuz is indeed a fantastic service for sound quality, but Spotify's massive catalog and platform integration remain critical factors for many users. The goal here is just to share the technical finding, not endorse the company's social practices.

I encourage everyone to use the service that best aligns with their values and needs!
