what is the sample rate of spotify stream (libspotify)?
spotify
Solution
The audio you get in the `music_delivery` callback is indeed raw PCM data. The sample rate and bit depth is described in the `sp_audioformat` struct given in that callback.
The audio format can change depending on the track being played, so make sure your audio pipeline can deal with that.
Problem
What is the sample rate of spotify stream? The call back function "music_delivery" in libspotify example playtrack takes audio format from libspotify directly. Is the audio decoded to be raw wave data already? Is the sample rate 44.1kHz/16bit by default? Does the libspotify convert the original audio sample rate to be 44.1KHz/16bit? Thanks.
