Question

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.

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.

I've played more than 60 tracks and all of them has 44.1kHz sample rate. Do you have any tracks that are not 44.1kHz so I could try? Thanks. – mile Jun 05 '12 at 13:00
