Hi,
I am working on a problem that involves multiple smartphones/tablets. All devices are playing the same sound with synchronization difference up to +- 5ms. Now, there is an echo issue and I want to cancel acoustic echo on the phones.
So, keeping this problem as simple I have to create an echo canceller for multiple speakers and one mic scenario. I have already read papers regarding stereo echo cancellers but that doesn't solve my problem.
Any help will be appreciated.
Regards,
Khubaib
Dear Dr Ahmed:
A common issue with conference calling is a phenomenon called acoustic return echo. Nureva has developed a unique and innovative approach to effectively deal with acoustic return echo by adapting and calibrating the acoustic echo canceller in a manner that other systems are unable to achieve.
