Hi Aswani,

We will be using this in Android on OMAP4 (tablet, but will also be released to pandaboard) where it will stack above ALSA in the Audio HAL layer.

Thanks and Regards,

Samant

got reference from http://e2e.ti.com/support/embedded/f/356/t/109612.aspx .

For creating AER alsa plug-in, we need AER shared libraries (dynamic) but we have static libraries(aer_a.av7A, aer_c.av7A) available from the cortex-A8 AER. We are facing issues like "Linking the shared library against the static library is not portable! " while building the AER alsa plug-in.

Can TI provide the AER dynamic libraries(.so)?

Hi Ashwani,

Since, the AER is a very low level signal processing component there is no plan for release of a shared library. But we are planning/working on a higher level component which will include AER and other components for Linux/Android and that *may* be in a shared library form.

Though you can wrap existing AER component in a shared library. Try this out http://stackoverflow.com/questions/1614970/c-linker-question-dynamic-and-static-library-dependency.

Hope it helps.

Thanks,
