Why are MP3 audio files and JPEG image files so much smaller and more compressed than their loss less digital counterparts?

Why are MP3 audio files and JPEG image files so much smaller and more compressed than their loss less digital counterparts? The most common algorithm for compressing digitized versions of analogue sources is the Fast Fourier Transform, or FFT. Because FFTs are so widely used, computer scientists need very efficient algorithms to calculate them. Computations arranged in ‘butterfly’ formation are […]
