X-CUBE Audio support for STM32H7

Hi Michel 

  I am working on an Audio project using STM32H7A3VGH6 and STM32H743VGH6.  I am interested in rate conversion from 44.1K to 48K ( I have a float version ) in Int16 and the Multi band DRC mentioned above.

 I did find the SRC441 in the X-Cube-Audio libray though the documentation mentions support for the STM32F series.

 Hope this will work for the H series as well.

 

 I did not find the MB-DRC though there is a SVC code.  Is this the same as MB-DRC ( the document seems to indicate it as a single band only ).  Is there a link where I can get the code for this ?

    Hello @SChak.1

     

    Regarding SRC441 library, I am not the right guy to know if it works on your platform; I forwarded your question to the right person.

    Regarding MDRC, it is part of x-cube-audio-kit (it is not available as a library), it is not inside x-cube-audio library; VLC which is inside x-cube-audio library is a simpler algorithm which may perhaps fulfill your requirement (but it is not multi-band).

    Hello @MichelM and @SChak.1,

    Regarding SRC441 library, there already are the Cortex-M7 binaries so it should work on STM32H7 boards.

    Best regards,
