It does<br>shrink for AMR modes 2, 3, 4, 6, and 7 but doesn't shrink for<br>AMR modes 0, 1, 5, and SID frames because we only remove 6 bits.<br>So old code generated truncated AMR packets for those AMR modes.<br>This patch fixes the length calculation by properly counting bits.<br><br>Proper bit counting is also bringing us one small step closer to<br>properly handlig multi-frame AMR packets.<br><br>Change-Id: I0462e054a0adc9080456f3eeea9cab7c229cdb70<br>---<br>M include/osmocom/netif/amr.h<br>M src/amr.c<br>M tests/amr/amr_test.c<br>M tests/amr/amr_test.ok<br>4 files changed, 147
