COMPRESSOR TARGET CURVE TO AVOID BOOSTING NOISE

The processing of audio signals during playback is provided, so that audio signals that fall below a specified threshold loudness level are processed to avoid making unwanted background noise audible.N-channel audio is received from a playback volume controller/leveler (101). The level of the audio is compared with a threshold level. If the level is greater than the threshold level, the audio isprocessed with a first amount of gain in accordance with a first dynamic range control (DRC) compression curve that is tuned for professionally produced audio. If the level is less than or equal to the threshold level, the audio is processed with a second amount of gain in accordance with a second DRC compression curve that is designed to avoid boosting unwanted background noise. After applying the gain to the audio, the audio is sent to a downstream device. 提供回放期间的音频信号处理，以使得低于指定阈值响度电平的音频信号被处理以避免使得不想要的背景噪声能够被听到。从回放音量控制器/调节器(101)接收n声道音频；将音频的电平与阈值电平进行比较；如果该电平大于阈值电平，则根据针对专业制作的音频进行调谐的第一动态范围控制(DRC)压缩曲线，以第一增益量处理音频；如果该电平小于或等于
