Digital Signal Processing or DSP manipulates digital signals using algorithms. A key element is the Fast Fourier Transform (FFT), which can break down a complex signal into 1024 simpler parts for analysis in just a few milliseconds. This improves audio and image quality.
The Andes mountain range is incredibly long. It stretches over 7000 kilometers along the western edge of South America. That's longer than the distance across the United States.
