A recent post asking about file zipping made me wonder…does audio compression do the same thing? Is it finding pieces of the sound that are identical and then saving them only once in the MP3 file? It’s one thing to identify patterns in a text file and only save one version of the repeating parts, but somehow that doesn’t seem feasible with audio since things like music have so much complexity.

So audio is actually filtered in ranges the human ear can actually hear in Mp3. A microphone captures sound that’s out of the range of human capacity for sound. It removes those pitches to save some space. As for actual compression algorithms, I’m not sure.
