摘要

我们描述了音频编码中的六种比特分配算法。每种算法都源于最小化不同的感知动机目标函数。这些目标函数中有三个是现有目标函数的扩展，另外三个是新的。封闭型位分配方程有五种，第六种需要迭代求解。

Perception-based bit-allocation algorithms for audio coding

We describe six algorithms for bit-allocation in audio coding. Each algorithm stems from the minimization of a different perceptually-motivated objective function. Three of these objective functions are extensions of existing ones, and three are new. Closed-form bit-allocation equations result in five cases, and an iterative approach is required in the sixth.
