G726 Quality improvement

Started by Raj Baretto August 21, 2003
Hi ,

I just finished implemeting G726. I found that the quality is
very low. Can some one give me sugesstion about improving the
quality of G.726. I was told that using some of the modules from
CELP will improve the quality. But others disagree saying it will
not improve rather low down. Can some one kindly suggest some
method where quality can be improves?

Rgrds,
Raj



Hi Raj
If your code meets the test vectors perfectly there will be a good quality
output. See that your out put matches for all test vectors.

Srinath,
I have few test vectors,but no sure if they are standard ones.
Could You please help me to get those? Also I am talking about the
lowest 8KHz sampling. For higher sampling rate the quality is
better, but I am interested in 8Khz one.
Kindly give me ur suggestions on this.

Rgrds,
Rajendra
