摘要 提出了一种AAC音频编码量化算法的迭代初始化与搜索的改进算法,该方法能有效减少量化器的迭代次数并且在不同风格的音频曲目与音频帧之间的编码时间相对稳定,从而使编码器更适用于实时编码的应用。 An improved iterative algorithm for the AAC audio encoder is proposed. The algorithm can effectively reduce the loop count of quantization iteration and give more stable timing performance among different input audio styles and audio frames which makes the encoder more suitable for real time audio encoding application.
