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