Spotify currently streams music in the Ogg Vorbis format, which supports a maximum bitrate of 320 kbps. However, the actual bitrate used may vary depending on the quality selected by the user, ranging from 96 kbps to 320 kbps. Spotify does not offer lossless or high-resolution audio streaming options like 16 or 24-bit.
It's worth mentioning that lossless audio formats like 16 or 24-bit are typically associated with higher audio quality and are often preferred by audiophiles or those with high-end audio equipment. However, for the majority of listeners, Spotify's highest quality setting at 320 kbps should provide a satisfying audio experience.
