The detail of OFL (Original File Length)
I'm looking for the detail of OFL(Original File Length).

For example,  I'm looking for the following info

- Data size of OFL
- Data syntax of OFL
- How should the decoder use those data?

I purchased the AES paper of OFL.

Could you tell me a little more about OFL?

For mp3, mp3pro, both?

Thanks for your comments.
And I'm sorry my reply is late.

If possible, I want to know both mp3 and mp3pro.
At least, I want to know mp3.

decoded audio signals are also typically no longer time-aligned with the original signals

mean that the time between events in the audio stream (say between one cymbal clash and the next) are a different duration than the original audio from which the mp3 was made? If so, this would be a form of jitter, no?

That would be some pretty serious jitter!

No, given the title ("Original File Length"), it appears to be referring to the encoder delay and padding that's added to each encoded MP3 file, and how to accurately remove it upon decoding and playback.

Could I confirm the OFL?

I think OFL is meta data and has the syntax of the specification.
Does OFL have common syntax?

Is it just a concept?
