Posted on March 07, 2012 at 08:29I tried wave playout using the normal mode i.e. through Flash memory and the AUDIO_MAL_MODE_NORMAL, this worked fine.
However when I try playout via uSDCard I find that the output is very noisy and defnitely corrupted.
The readme file says that for playout via an external device the AUDIO_MAL_MODE_CIRCULAR should be used which would require implementation of certain functions such as the EVAL_AUDIO_TransferComplete_CallBack(). Has anyone tried this ?
At present my playout is implemented using two ping pong buffers but I think there must be some access timing delays that lead to the poor quality of output. Any ideas anyone ?
