Why is Tidal HiFi showing such low kbps?

[Nstzya]

So far I am liking my trial of the WiiM Pro as a digital transport into my DSP active speakers using Tidal HiFi streaming. The app confirms Tidal HiFi at 16/44.1 but shows a bitrate of only 600-800 kbps - far below CD rate of 1411. Why might this be??

Think the define CD quality as Red Book says "up to 1411"...so it may depend on their source material.

It includes a stream compression.

Audio CDs must ensure only the, from today's point of view, low transmission rate of 176.4 kB/s, (corresponding to a transmission rate of 75 blocks per second).

So Tidal is compressing? Lossless, I presume.

In terms of the stream/file compression it's lossless.

As do most streaming services when they use FLAC. If you were sending a CD quality WAV file which isn’t compressed, you‘d get 1411kbps. If you use FLAC, it‘s generally significantly less - lossless compression is FLAC’s raison d’être after all
