Skype calls become intermittent after increasing Audio DMA Buffer. During previous debugging, it was found that increasing Audio DMA Buffer would cause video playback to become stuck, which was very s...
I want to use STM32 to make a 4*4 matrix keyboard. How do I configure the row GPIO connected to VDD through a pull-up resistor? How do I configure the GPIO port for column output? It's a small questio...
On the surface, mixing is a very simple matter. All you have to do is adjust some knobs until everything sounds good. But in practice, you will realize that mixing is indeed a very complex technology....
