Audio Codec is a device or program that compress and decompress digital audio data According to given audio file format. The term codec is a combination of coder-decoder. The object of a codec formula is to represent the high fidelity audio signal with minimum Number of bits while retaining the quality. This can effectively reduce storage space.

Audio Compression - AS2010362 27. 28. MPEG Audio Layer II 28 • A simple enhancement of Layer I. • It improves compression performance by coding data in larger groups. • Bit rates of 128 kbits/s per channel. • Improves performance by representing the bit allocation, the scale factor values, and the quantized samples.

format, MPEG-2 AAC (Advanced Audio Coding) is unconstrained and can therefore provide better coding efficiency. The most recent development is the adoption of MPEG-4 [ISO, 1999] for very-low-bit-rate channels, such as those found in Internet and mobile applications. Table 1 lists the configuration used in MPEG audio coding standards. 3
