Abstract: 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.
