Decoding only a certain frame results in different values than when decoding the entire file
Sorry, it seems I have only replied to Lakhdar, not to the newsgroup.
Below is my reply to Lakhdar, and I would like to make it more clear
now, using some pseudo values for simplicity:
I read bytes 1 to 124 from my encoded spx file.
I decode themt and get the values:
---Frame 1----
-293
-8234
2134
17
---Frame 2----
-9323
-732
189
2329

Decoding only a certain frame results in different values than when decoding the entire file
...set to the default state.
- In case 1, the decoder memory state has been modified by the
processing of FRAME 1.
If I got it wrong, please provide more details.

Decoding only a certain frame results in different values than when decoding the entire file
I found out something:
The more frames I decode before the frame that I actually want to
decode, the better the quality becomes.
For example when I basically want to decode frame #100, I read frame #80
to #100, and then frame 100 has the quality that I need.
Why? Is there any information on this behaviour?
Thank you.

...t decodes, the state changes. You're trying to start
somewhere in the middle with the initial state rather than with the
state it would have if you started from the beginning and decoded it
all. As you've noticed, it can recover from lost frames over time.
This is just repeating what Lakhdar Bourokba already said though.
As for your question about the header, it really depends on how you're
saving the encoded file.
