| 802 | FFT = Fast Fourier Transform |

| 804 | MPEG-1 Layer 3 retains Layer 2's 1152-sample window, as well as the FFT polyphase filter for |
| 805 | backward compatibility, but adds a modified DCT filter. DCT's advantages over DFTs (discrete |
| 806 | Fourier transforms) include half as many multiply-accumulate operations and half the |
| 807 | generated coefficients because the sinusoidal portion of the calculation is absent, and DCT |
| 808 | generally involves simpler math. The finite lengths of a conventional DCTs' bandpass impulse |
| 809 | responses, however, may result in block-boundary effects. MDCTs overlap the analysis blocks |
| 810 | and lowpass-filter the decoded audio to remove aliases, eliminating these effects. MDCTs also |
| 811 | have a higher transform coding gain than the standard DCT, and their basic functions |
| 812 | correspond to better bandpass response. |
| 813 | |
| 814 | MPEG-1 Layer 3's DCT sub-bands are unequally sized, and correspond to the human auditory |
| 815 | system's critical bands. In Layer 3 decoders must support both constant- and variable-bit-rate |
| 816 | bit streams. (However, many Layer 1 and 2 decoders also handle variable bit rates). Finally, |
| 817 | Layer 3 encoders Huffman-code the quantized coefficients before archiving or transmission for |
| 818 | additional lossless compression. Bit streams range from 32 to 320 kbps, and 128-kbps rates |
| 819 | achieve near-CD quality, an important specification to enable dual-channel ISDN |
| 820 | (integrated-services-digital-network) to be the future high-bandwidth pipe to the home. |
