摘要： This invention relates to an improved memory storage system which allows selective ranges of memory locations, which can also be referred to as virtual memory banks, to be enabled and disabled. The ranges of memory locations can be disabled to avoid refreshing unused memory location and to eliminate faulty memory locations. Also, the ranges of memory locations can be treated as blocks or banks of memory regardless of the physical chips used to store the data. In other words, if a memory bank has a capacity of 16 MB, the range of memory locations may be a portion of the total capacity of this memory bank, for example 8 MB or 4 MB, and the remainder of the memory bank can be unaffected or be the subject of another range of memory locations. In a preferred embodiment, the ranges of memory locations is at least 2 MB in size.

摘要： Different dynamic range control values are applied to the 2-channel and m-channel outputs without repeating the inverse transform of the audio samples. First, m-channel dynamic range control values are applied to audio samples in the frequency domain (“frequency samples” or “frequency coefficients”). The frequency samples are then inverse transformed to generate audio samples in the time domain (“time samples”). The time samples are duplicated to two sets where the 2-channel dynamic range control values are applied to one set of time samples. 2-channel dynamic range control values include 2-channel final scales that, when multiplied with the first set of time samples, at least partially remove the effects of the m-channel dynamic range control and readjust the dynamic range for 2-channel output. The first set and the second set are then windowed. Thus, independent dynamic range control for the m-channel output and the 2-channel output are achieved without repeating the inverse transform, which is computational and/or memory intensive.

摘要： Different dynamic range control values are applied to the 2-channel and m-channel outputs without repeating the inverse transform or the windowing of the audio samples. First, m-channel dynamic range control values are applied to audio samples in the frequency domain (“frequency samples” or “frequency coefficients”). The frequency samples are then inverse transformed to generate audio samples in the time domain (“time samples”) and windowed to generate windowed time samples. The windowed time samples are saved and the 2-channel dynamic range control values are applied to the windowed time samples. 2-channel dynamic range control values include 2-channel scale factors that, when multiplied with groups of the windowed time samples, at least partially remove the effects of windowing and the m-ch dynamic range control values applied in the frequency domain and readjust the dynamic range for 2-channel output. Thus, a set of windowed time samples under m-channel dynamic range control values and a set of windowed time samples under 2-channel dynamic range control values are generated without repeating the inverse transform or the windowing, which are computational and/or memory intensive.
摘要翻译：不同的动态范围控制值被应用于2声道和m声道输出，而不会重复音频样本的逆变换或窗口化。首先，将m声道动态范围控制值应用于频域（“频率采样”或“频率系数”）中的音频采样。然后对频率样本进行逆变换，以在时域（“时间样本”）中生成音频样本，并窗口化以生成窗口化时间样本。窗口化的时间样本被保存，并且2通道动态范围控制值被应用于窗口化的时间样本。 2通道动态范围控制值包括2通道比例因子，当与窗口时间采样的组相乘时，至少部分消除窗口效应和应用于频域的m-ch动态范围控制值，并重新调整 2通道输出的动态范围。因此，在双通道动态范围控制值下的m信道动态范围控制值和一组窗口时间样本下的一组窗口化时间样本被生成，而不重复计算和/或存储密集的逆变换或开窗。
