How MP3 Throws Sound Away

It deletes sounds your ear can't hear anyway

An MP3 can be a small fraction of the CD it came from. What does it throw away, and why don't you miss it?

You'll find out

  • How a loud sound hides a quiet one
  • How your ear sorts pitches
  • The song that nearly broke MP3

Why it matters

Every song you stream is squeezed with the same trick. It works because of what your ears skip.
