Hi,
I'm having a problem with my adpcm codec and I will appreciate any
advices/suggestions given.
I have downloaded my g726 adpcm codes onto a dsp(c5510) and I fed in
an analog signal(sound card output) into the processor. The output is
however disappointing as there were a lot of noise and static.
The functionality of the adpcm codes is not in doubt as I had used the
ITU test vectors on the codes and the codes were able to encode and
decode correctly.
Can anyone with experience in this area advise me on how I can
actually improve the codes so that it will be more usable?
Thanks.
Regards,
Issac
