few fundamental questions on AMR speech coding

Started by subrata chatterjee April 23, 2002
Hi friends,
I have some fundamental queries regarding AMR speech
codec. 1) Why we are using two windows in case of
12.2kbit/sec mode?

2)What is the utility of using auto correlation after
windowing?

3)What is the utility of using lag windowing after
auto correlation ? Anyone aware about the answers please reply soon.
Thanks in advance
bye
