hi everybody!

I want to input two audio signals (electronics completed from mic to stm32f4, 1 analog pin and 1 ground) to the stm32f4. Then I want to mix the two audio signals with one signal at half volume and the other at full volume. The mixed signal then needs to be an audio output to a speaker, from the stm32f4

I should be able to do this using the DSP libraries right?

Can someone please direct me on how I can start to do this. It will be greatly appreciated.
