Audio application on Beagle Board

Hi,

I want to test a loopback Audio application on ARM which will internally communicate with DSP Processor and give it back to the ARM side. What all tools and softwares are required? I am stuck. Tell me the tool for Video application also. I have installed cross compilation arm tool chain from http://www.codesourcery.com/gnu_toolchains/arm/portal/release313
Is there any trial version Sofware available along with G711 / H264 libs and API’s.

Regards,
Vineet
