Spotify is seemingly preparing to launch a lossless audio version of its streaming service. The offering, which is currently called Spotify Hi-Fi, will offer lossless CD-quality audio to users -- similar to what Tidal offers in its Hi-Fi service. From a report: For an extra $5 to $10, you could get all the features in Spotify Premium as well as lossless high fidelity streaming. There could also be a couple of new features. What is lossless quality anyway? Currently, if you go into Spotify's settings and choose the highest quality, Spotify serves you 320kbps audio files. It's very high quality, but it's not perfect -- in other words, it's a compromise. This way, files are still quite small and load quickly. Lossless files are perfect copies of the songs on an audio CD. They are then compressed, but without any quality loss.
