Explain audio encoder and decoder used in MPEG.
$$\text{Figure 2.1 MPEG Audio Encoder}$$ $$\text{Figure 2.2 MPEG Audio Decoder}$$ i. The principle of MPEG audio compression is quantization. The values being quantized however are not the audio samples but numbers (called signals) taken from the frequency domain of the sound.

Sep 02, 2010The block diagram for H codec is shown in Figure 1. The Encoder [Figure 1(a)] includes two dataflow paths, a "forward" path (left to right, shown in blue) and a "reconstruction" path (right to left, shown in magenta). The dataflow path in the Decoder [Figure 1(b)] is shown from right to left to illustrate the similarities between Encoder[PDF]
