🧠 How MP3 Works

MP3 compresses audio with loss using a psychoacoustic model — it removes frequencies the human ear cannot distinguish. The file is a stream of independent frames, each encoding ~26 ms of sound. Here is how it works:

🎵 PCM original sound (uncompressed) 👂 Psychoacoustics removes sounds the ear can't hear 📊 MDCT sound to frequencies (like DCT in JPEG) 📦 Huffman lossless compression 🎶 Frames stream of blocks ~26 ms each 💾 .mp3 + ID3 tags (metadata)
