Personal network conference facilities with vs1003

Post by vito1989 » Sat 2013-01-05 11:34

hi support,
one client is doing the Personal network conference facilities with vs1003,i find we have a VOIP Speaker Phone,it have a feature that VOIP Speaker Phone supports Acoustic Echo Cancellation,but i don't understand which module is the Acoustic Echo Cancellation module,
what is the function of vs1000?
does the vs1000 only provide USB interface ?
how to cancel Acoustic Echo?
do the LINEIN and MIC use at the same time?

the client give me this circuit diagram showed following,he want to use two vs1003,a audio USB chip,support Acoustic Echo Cancellation ,please do a simple check!thanks

continue orignal discussion,
i read all docments about the voip,but i don't find which module can solve Acoustic Echo Cancellation,if do Acoustic Echo Cancellation through software,how to write the code?You know,the vs1003 can't realize full-Duplex,but the voip is full-Duplex,how to realise it?
then,please see the VoipAcousticV211.pdf,especially,the DREQ of vs1003,XCS of vs1003 and XDCS of vs1003 ,i don't know which chip is the main chip,how to communicate between them?


last,today i modified the circuit diagram based what the client said,because i don't understand our voip,so i need your help,pls have a look?

ps:the difference between the client and our voip is the client also have a USB audio chip ,so he need't use the vs1000,the main function is similar to our voip,in a word,pls have a look!!!thanks

actually,my main question is about our VOIP :
does the vs10001 control vs1003,or the vs1003 control vs1000?why do the DREQ pin and XDCS pin of vs1003 connect with the GPIO pins of vs1000? :?: :!:

no one answer me?
The AEC is very difficult to get working. A working AEC requires careful electrical, mechanical, acoustic and software design. We are not sure how we can give support for AEC. We are thinking about it.

Hi!

I am not sure (I did not do the VoIP), but I think that in the VoIP, the VS1000 uses the VS1003 for many purposes: sometimes it configures the VS1003 into a voice IC and at other times it configures the VS1003 into an MP3 player or something.
