Re: Decoding only a certain frame results in different values than when decoding the entire file

When I already decoded something, and the decstate is not erased or 
reset, shouldn't that be sufficient to decode other frames with a good 
quality?

For example, when I have decoded 30 frames without decoding the previous 
frames, the sound quality may not be too good, but afterwards the 
decoder should (in my opinion) be in a "good" state.
But when I decode other frames afterwards, it is as if I did not decode 
anything before...
Can someone explain this?

Does the decoder need to have decoded the adjacent previous frames or is 
it sufficient that the decoder has just decoded anything?

Thank you.
