You'd need to use a software CODEC to convert the WMA, MP3, OGG or whatever into a PCM format that can be pumped to the audio codec.

Hi  ghr.hadi,

I recommend you the SAI-Audio'' example in the

http://www.st.com/content/st_com/en/products/embedded-software/mcus-embedded-software/stm32-embedded-software/stm32cube-embedded-software/stm32cubef7.html

package located at this path: STM32Cube_FW_F7_V1.4.0\Projects\STM32756G_EVAL\Examples\SAI\SAI_Audio This example uses an audio codec driver wm8994 located at this path STM32Cube_FW_F7_V1.4.0\Drivers\BSP\Components\wm8994. The audio codec driver  consists of three independent layers:  - Codec Hardware layer: which controls and communicates with the audio codec    (WM8994) implemented on the evaluation board.  - MAL (Media Access Layer): which controls and interfaces with storage media    storing or providing the audio file/stream.  - The high layer: which implements overall control and interfacing API allowing    to perform basic audio operations (Init, Play, Pause, Resume, Stop, Volume    control and audio file pointer management) -Hannibal-

Hi ghr.hadi,

Check the SAI (serial Audio interface) parth  in the STM32F7 reference manual

http://www.st.com/content/ccc/resource/technical/document/reference_manual/c5/cf/ef/52/c0/f1/4b/fa/DM00124865.pdf/files/DM00124865.pdf/jcr:content/translations/en.DM00124865.pdf

. The code of example is in the location that I have already mentionned. There is another example in the same package called ''Audio_playback_and_record'' ready for use on STM32746G-Discovery at this path STM32Cube_FW_F7_V1.4.0\Projects\STM32746G-Discovery\Applications\Audio Here is the STM32746G-Discovery user manual

http://www.st.com/content/ccc/resource/technical/document/user_manual/f0/14/c1/b9/95/6d/40/4d/DM00190424.pdf/files/DM00190424.pdf/jcr:content/translations/en.DM00190424.pdf

. You find in page 15 a description of the Audio hardware and software enviroment. For the example follow the instructions on the readme files. -Hannibal-
