Has anyone any info on the delay field in a VBRI header, there is one value (a word) that seems too big for the encoder delay (such as 2000 when the real delay would be around 570), it might contain padding as well?

If the VBRI is a valid frame, the delay might include the VBRI frame.

Good thinking, will try.

Excellent now have sample perfect FhG gapless decoding...
