When there is a broken (incomplete) mp3 frame in an mp3 file, how do decoders handle them? Are they just ignored, partially played, some recovery is made, or something else? If such broken frame occurs in the middle of a file rather than at the end, how does it affect decoding the next adjacent frame? Suppose we have two mp3 frames f1 and f2 next to each other in that order, and f1 is incomplete. When decoding f1, is it
- possible to recognize f1 is broken (do something for that) and successfully decode f2,
- or the beginning of f2 is somehow mis-considered as part of f1, so f2 fails to decode?

How about garbage data after a valid frame? Are they completely ignored until another valid frame is detected?
