正弦波模型已被证明是一种行之有效的语音信号编码技术。近年来．在低码率的音频编码算法中也开始应用它。采用 ＭＰ算法来处理正弦波模型，根据音频信号的特点对抽象的 ＭＰ算法进行改进和变化。它在分析时将合成过程考虑在内，保证了分析与合成的一致性。在合成时，采用增强技术可以有效地改善音质。还讨论了 ＭＰ算法的正交化缺陷和它对合咸信号质量的影响。
Sine wave model has been proved to be an effective speech signal coding technique. In recent years. It is also used in low bit rate audio coding algorithms. The MP algorithm is used to process the sine wave model, and the abstract MP algorithm is improved and changed according to the characteristics of the audio signal. It takes the synthesis into account in the analysis, ensuring consistency of analysis and synthesis. In the synthesis, the use of enhanced technology can effectively improve the sound quality. Also discussed MP algorithm orthogonal defects and its impact on the salty signal quality.
