音频处理器在语言广播中有着广泛的应用。它既有对音频信号进行幅度(增益)提升、限制压缩等功能,又具有频率均衡等用途。在中波调幅广播中使用音频处理器的目的:一是为了提高发射机的平均调幅度,以增加收音的响度;二是根据中波调幅接收机的频带特点改善发射一一收音机链路频响指标,以改善收音质量。 音频处理器在电视广播中使用,主要是控制伴音音量,使不同节目之间的音量大小保持一致,并符合电视发射机对伴音输入的要求(电平、动态范围及频响)。
Audio processors have a wide range of applications in language broadcasting. It has the audio signal amplitude (gain) to enhance, limit compression and other functions, but also has the frequency equalizer and other purposes. The purpose of using an audio processor in AM AM: First, in order to improve the average amplitude modulation of the transmitter to increase the loudness of the radio; Second, to improve the frequency response of the transmitting radio link according to the characteristics of the frequency band of the AM AM receiver Indicators to improve the radio quality. Audio processors are used in television broadcasts to control the volume of sound, keeping the volume of different programs consistent and meeting the requirements of television transmitters for sound input (level, dynamic range and frequency response).
