Hello Pasi
Thanks for your reply. We have completed the tuning of vs1063a. Now vs1063a can work with our PC audio codec tool well. the voice is clear. The noice is because our pc codec tool use a-law, but vs1063a is set to u-law.
thanks again.
kind regards.
Wayne.

Re: issue of vs1063's encoding gain
Hello Pasi
In our use case, one side is vs1063a, the other side is PC. When I test ADPCM encoding format, it seems that the IMA ADPCM enc/dec source code is not adapting to VS1063a's. Do you have IMA ADPCM open source code that could work with vs1063a?
kind regards.

Re: issue of vs1063's encoding gain
Hello Pasi
I am not sure what is your means.
What result would be if testing with ADPCM or G.722? The isuue rate would be small than PCM, or it would not occour the issue?
kind regards.
