The following test sequences are specific to the G723.1 v5.1
VAD/DTX/CNG mode of operation :
Encoder sequences :
-------------------
lbccodec -c -r63 -v dtx63.tin dtx63.xco
lbccodec -c -r53 -v dtx53mix.tin dtx53.xco
lbccodec -c -rdtxmix.rat -v dtx53mix.tin dtxmix.xco
The files *.xco are to be compared with the reference
bitstream files *.rco
Decoder sequences :
-------------------
lbccodec -d dtx63.rco dtx63.xou
lbccodec -d dtx53.rco dtx53.xou
lbccodec -d dtxmix.rco dtxmix.xou
lbccodec -d -fdtx63e.crc dtx63e.tco dtx63e.xou
lbccodec -d dtx63b.tco dtx63b.xou
The files *.xou are to be compared with the reference
output files *.rou
