Development board for audio recording and playback?

[Lalogarcia91]

Hello, first post here.

I have Stm32 Nucleo board and I'm making some tests on this for the first time.

Is there a eay to record audio and play sound with this board? I also intend to store those recordings directly in a USB - A.

Any suggestions? If not with Nucleo, what do you recommend?

Thanks,

Ed.

Hello @Lalogarcia91 

Which board are you using?

I would recommend starting with the Audio examples available under the STM32CubeXX firmware package which is relevant to your device.

As example, you will find the ready to use "Audio playback and record" application under: 

• STM32CubeF4:STM32Cube_FW_F4_Vx.x.x\Projects\STM32469I_EVAL\Applications\Audio\Audio_playback_and_record
• STM32CubeF7: STM32Cube_FW_F7_Vx.x.x\Projects\STM32756G_EVAL\Applications\Audio\Audio_playback_and_record

You may update the application according to your needs. You find a readme file describing how to test the examples.

Hope this help!

Hello Imen, thanks for your time.

Currently I'm using a Nucleo-F401RE with STM32 Cube IDE.

No luck so far on audio rec, playback and storing recs in USB.

On the other hand, the links you posted take me to nowhere related to Audio as you mentioned.

I was about to buy a Discovery board to try get this thing running.

Hello, I also have the stm32F407 discovery model. When I hold down the first button with the help of the buttons on the card, I want it to record the sound to the USB for as long as it is pressed, and when I press the second button, I want it to output the recorded sound through the speaker. can you help me on this issue
