I was considering how to write my own application to read SYLT frame information from an ID3 tag, but do not know enough about the MPEG format to know how to convert MPEG frame timing to real time in the case that the SYLT header indicates frame timing instead of millisecond timing. What's the minimum amount of handling I need to implement to ensure that I can account for the timing conversion in both a static or a variable bit rate audio file? Thanks in advance for any help you could provide.<br>
