Can you please help me with this problem??
I have been working on AM335x sitara evm and my project needs self diagnosis of the captured audio from the mic through the speaker on the same board (we have re-worked on the evm to add the mic and speaker). In the application it is preferred that the user only requests for the audio test to be performed and the software (have to implement; but no Idea how to do so) need to check the quality of the audio and based on the statistics it has to give the test result.
Please provide me some ideas how to implement this self diagnosis test for audio quality. If you feel the question is unclear or could not understand please let me know.....
