The following picture shows a block diagram for the most generic SA decoding process, i.e. the one allowed by the Main Synthesis object type. SA Application Scenarios. The versatile toolset of MPEG-4 Structured Audio enables a rich variety of applications. The main scenarios are the following: MIDI over MPEG-4.

Each MPEG audio frame contains either 384 (Layer 1) or 1152 (Layer 2) audio samples per channel. However, each input buffer to the encoder may contain any number of PCM samples. The size of each input buffer must be a multiple of the block alignment.

Figure 1 shows block diagrams of the MPEG/audio encoder and decoder. The input audio stream passes through a filter bank that divides the input into multiple subbands of frequency. The input audio stream simultaneously passes through a psychoacoustic model that determines the ratio of the signal energy to the masking threshold for each subband.

$$\text{Figure 2.2 MPEG Audio Decoder}$$ 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. ii. The fact that the compression ratio (or equivalently bit rate) is known to the encoder means that the encoder knows at any time how …
Introduction to MPEG 2 Video Compression - Bretl

A simplified MPEG-2 encoder and decoder are shown in the MPEG Coder/Decoder Diagram. Encoding: The encoding process for P and B pictures is explained as follows. Data representing macroblocks of pixel values for a picture to be encoded are fed to both the subtractor and the motion estimator. The motion estimator compares each of these new macroblocks with …
