From: Context-based adaptive arithmetic coding in time and frequency domain for the lossless compression of audio coding parameters at variable rate

Figure 7

Average compression percentages of quantized norms and quantized MDCT coefficients. The x-axis represents the coding modes (1 to 7), and the y-axis represents the compression percentage of all kinds of the parameters with different entropy coding. The solid line presents the compression percentage of the quantized norms coded by the context-based adaptive arithmetic coding compared to Huffman coding. The dashed line presents the compression percentage of the quantized norms coded by the adaptive arithmetic coding compared to Huffman coding. The dotted line presents the compression percentage of the quantized MDCT coefficients coded by context-based adaptive arithmetic coding compared to Huffman coding. The dash dotted line presents the compression percentage of the quantized MDCT coefficients coded by the adaptive arithmetic coding compared to Huffman coding.
