\n1. General Information<\/p>\n

Digital audio compression technology provides people with a more efficient method of transmitting and storing audio. There are many techniques for audio compression, and their complexity, audio compression quality, and compression ratio vary greatly. Such as: \u03bc-law audio compression algorithm, its features are simple, but the compression ratio is very low, but the sound quality is average. According to CCITT G. 711 suggested that the natural log quantization process can provide relatively high precision quantization when the input amplitude is relatively small, while for large-scale signals with a relatively small probability of occurrence, the quantization noise it is relatively large. This quantization method makes the 8-bit digital quantization signal equivalent to 14-bit linear quantization in terms of quantization noise. ADPCM compression encoding takes full advantage of the relatively small amplitude variation characteristics of adjacent sample values, and the output result of the encoding is the difference between the current sample value and the predicted value. Although the fidelity of ADPCM encoding is high, its compression ratio is relatively small, and it can only reach a compression ratio of 4\/1. The improved ADPCM encoding method includes the improved algorithm proposed by IMA (Interactive Multimedia Association), G. CCITT’s G. 721, g. 723 recommendations, etc<\/p>\n","protected":false},"excerpt":{"rendered":"
