uploading, then playing sounds on button presses

[Coder 0]

I want to add sounds to my button presses.  Is there a simple way to do that?
Can I store the sounds on board or do I have to upload each time the board is powered up.

Hello,

It depends on the sounds you intend to play.

What I mean is that you can generate sounds using digital pins using Pulse-width modulation (PWM) or Pulse-density modulation (PDM). Like this you can generate (from  your code) a sine wave.

Interesting... That is good to know.  I wanted to upload sound effects for button presses.  .wav files maybe?

Hi @Coder,

You may be able to store the .wav files on an SD card and then read them off the SD card into RAM and then play them out through an audio codec, but the implementation of how this might be done will vary on what board you are using (a microcontroller, a microprocessor, a FPGA, a SoC, etc).

Thanks,
