A Dynamic Range Control (DRC) processor produces a sequence of encoder DRC gain values, by applying a selected one of a number of DRC characteristics to a group of one or more of the audio channels or audio objects. The encoder DRC gain values are to be applied to adjust the group of ...
动态范围控制(Dynamic Range Control,DRC)将输入音频信号的动态范围映射到指定的动态范围,可以使声音听起来更柔和或更大声,即一种信号幅度调节方式。通常映射后的动态范围小于映射前的动态范围,因此称之为动态范围压缩。音频信号可以进行整体的动态范围控制,也可以划分为若干子带分别进行动态范围控制。DRC广泛应用于音频信...
This tutorial shows how to implement dynamic range control systems using thecompressor,expander,limiter, andnoiseGateSystem objects from Audio Toolbox™. The tutorial also provides an illustrated example of dynamic range limiting at various stages of a dynamic range limiting system. The diagram depict...
Libraries: Audio Toolbox / Dynamic Range Control Description The Compressor block performs dynamic range compression independently across each input channel. Dynamic range compression attenuates the volume of loud sounds that cross a given threshold. The block uses specified attack and release times to...
1. To turn on Dynamic Range Control, press and hold EFFECT for about 5 seconds on the remote. 2. Continue holding until ON - DRC appears on the display, confirming the function is active. 3. To turn off Dynamic Range Control, press and hold EFFECT for a...
The L3 splits the audio range into five bands (Fig. 1), but does not implement a separate limiter for each one; instead, there’s a single threshold, and an algorithm determines how to apply attenuation to each band so that peaks at the output are limited to that threshold. This approa...
指定AAC 解码器是否执行动态范围控制。 此枚举与 AVDecHEAACDynamicRangeControl 属性一起使用。语法C++ 复制 typedef enum eAVDecHEAACDynamicRangeControl { eAVDecHEAACDynamicRangeControl_OFF = 0, eAVDecHEAACDynamicRangeControl_ON = 1 } ; 常量
eAVDecHEAACDynamicRangeControl_ON 値:1 デコーダーは、ISO/IEC 14496-3 (表 4.105「extension_type フィールドの値」) で定義されているように、EXT_DYNAMIC_RANGE型の拡張ペイロードを含む任意の AAC ストリームに動的範囲制御を適用します。
