What's a MP3 File?

Anyone never heard of MP3? No. However, you may know these facts for the first time. The full name of MP3 is MPEG-1 Layer 3, not MPEG-3. MP3 is an efficient audio coding format with high compression rate. It converts audio files into smaller files with a larger compression ratio, and maintains the sound quality of the original files. MP3 is a part of ISO/MPEG standard. This standard has been constantly updated to meet the pursuit of "high quality, low quantity". Lastly, three audio coding and decoding schemes, namely, MPEG-1 Layer 1, Layer 2 and Layer 3, have been created. The MPEG-1 Layer 3 compression rate can reach to 1:10 to 1:12, while MP1 and MP2 to 4:1 and 8:1. The MP3 file with 1MB in size can play for one minute, while the WAV file with one minute CD quality (44100Hz, 16bit, dual channel) takes up 10M space. Thus, A 650M MP3 disc could play for more than 10 hours. By contrary, a CD disc with the same capacity saves only 1 hour or so music.

MP3 audio compression includes encoding and decoding. The encoding is to convert the data in WAV files into bitstream with high compression rate, and decoding is to recognize bitstream and turn it into WAV files. The acceptable frequency range of human ear is 20 Hz-220 kHz. MP3 intercepts a large number of redundant signals. The encoder transforms the original sound into specific frequency range through a hybrid filter bank. Using psychoacoustic model, the ear-sensible noise level is estimated and applied. After quantization, it is converted into Huffman coding and generate the MP3 bitstream. The decoder is much simpler. Its task is to extract the sound signal from the encoded spectral line components through inverse quantization and inverse transformation.
