The performance of the computer simulated 32
kbit/s LD-CELP coder was assessed by comparing it to the G.722 CCITT
standard wideband coder at 64 kbit/s as shown in Table 
.
The coding delay of the G.722 coder is 3 msec, whereas that of the
LD-CELP is only 0.94 msec. The result of Table also suggest that the
MOS quality score of the 32 kbit/s audio coder is close to 4.0.
