-Compiling AMRWB codec:
-======================
-
-To compile the amrwb codec, you need to download the source code from 
-"http://www.3gpp.org/ftp/Specs/html-info/26204.htm" and uncompress the 
-files inside an amrwb-code directory;
-
-or execute this commands:
-$cd amrwb-code
-$sh ./run.sh
-
-and run the "autogen" script again.

+Compiling AMRWB encoder:
+========================
+
+To compile the amrwb encoder, you need to download the source code from 
+"http://www.3gpp.org/ftp/Specs/html-info/26204.htm" and uncompress the 
+files inside an amrwb-code directory;
+
+or execute this commands:
+$cd amrwb-code
+$sh ./run.sh
+
+and run the "autogen" script again.
