Project Description:

Hi,

This project is for freelancers with Texas Instruments hardware (ARM+DSP) such as Beagleboard or Pandaboard. You will be programming an audio element for GStreamer and using C6Runlib to compile the code library that will run on the DSP.

You job is to

1). write a GStreamer audio element with a sink pad to accept up to 8 raw audio channels (up to 32-bit, 192khz per channel).
2). buffer those (upto) 8 channels into the DSP and return them back to the element. Each channel should have its own DSP processing thread.
3). each channel should be buffered/returned back to the GStreamer element unchanged.
4). each channel should have its own output source pad in the element.

See this diagram for clarification.
