Description
This program plays a WAV file pre-loaded into the external SDRAM. The
audio stream is sent through the SSC interface connected to the on-board AT73C213, enabling the sound to be audible using a pair of headphones.
Since the AT73C213 DAC requires that it be feeded a master clock multiple of the sample rate, it must be downloaded in external SDRAM, at address 0x20005000 it is difficult to handle any WAV file. As such, this example application is limited to playing files with the following format:
- Format: WAV
- Sample rate: 48 kHz
