Ordinary tapes record analog signals and do not have any bit rate. The average tape is played for 60 minutes on both sides and 30 minutes on one side. If a song takes 5 minutes to play, it can store about 12 songs. Converted to commonly used computer storage capacity, I think it should be roughly converted to the size of a WAV file.

The sound quality of tape playback depends on the equipment used for recording and playback. The most important thing is the magnetic head. In my impression, it seems that the better magnetic heads can reach about 50-15KHZ, but the poor magnetic heads cannot reach such a width.
