The cadence ‘12-11-11-12-11-11-12-11-11-12-11-11-11- (repeat)’ interleaves 13 frames containing no
sample blocks in every 160 frames. It provides a low long-term frequency drift for 44.1kHz of delivery
rate. Rates in sub-multiples (1/n) of 44.1kHz also follow this cadence AND interleave n empty frames.
Rates in multiples (n) of 44.1kHz applying this cadence contain n sample blocks in the non-empty frame
AND interleave an empty frame between non-empty frames (Table 6, page 18).
