apulSoft apUnmask是一个音频插件，用于放大被其他组件心理屏蔽的音频组件。
为此，apUnmask使用了部分高质量高质量音频压缩编解码器的检测器算法。提取将通过压缩去除的信号分量。由于
它们被时间和频率上较大的分量所掩盖，因此通常无法听到这些声音。apUnmask可以放大和雕刻被遮罩的内容并将
其添加到音乐中。
为了整形提取信号的频率，将其馈入线性相位图形均衡器。它具有贝塞尔曲线平滑的频率响应，而没有过冲。
结果是一种超现实的音频形式。该过程可帮助听众同时收听音乐的更多方面。apUnmask既可以用作母带效果，也可以用作单个乐器的智能激励器。
通常，有损音频压缩只会去除某些东西。数十年来的研究导致了巧妙的算法来检测在听众未注意到的情况下可以删除的内容-所有这些都可以节省数据量。使用apUnmask，您现在可以利用此研究功能来获益，提取和放大这些信号，并帮助听众的耳朵听到更多。
建议的工作
流程在主轨道或要增强的单个轨道上插入apUnmask。
调整主增益，直到可以看到合理数量的增量信号为止。
切换增量侦听按钮可听到“鬼音”的声音，这些声音将被作品编码解码器消除。这就是通常生活在音乐阴影中的东西。
使用分辨率旋钮进行实验，以找到最有趣的组件。
调整eq曲线以提取并增强好东西。
关闭增量收听并享受结果。

apulSoft apUnmask is an audio plugin to amplify components of the audio that are psychoacoustically masked by
other components.
To achieve this, apUnmask uses parts of the detector algorithm of the opus high-quality audio compression codec. Signal components that would get removed by compression are extracted. These can normally not be heard as they are masked by louder components in time and frequency. apUnmask enables amplifying and sculpting the masked content and adding it to the music.
To shape the frequencies of the extracted signal, it is fed through a linear phase graphical equalizer. It features a bezier curve smoothed frequency response without overshoot.
The result is a form of hyperrealistic audio. The process helps the listener to hear more aspects of the music at the same time. apUnmask can be used as a mastering effect or as an intelligent exciter for single instruments
Normally lossy audio compression just removes things. Decades of research have lead to clever algorithms to detect what can be taken away without the listener noticing – all to save on data size. Using apUnmask you can now use this research power to your benefit, extract and amplify those signals and help the listener’s ears to hear more.
SUGGESTED WORKFLOW
Insert apUnmask on the master track or an individual track to be enhanced.
Adjust the master gain until a reasonable amount of delta signal is visible.
Toggle the delta listen button to hear the “ghostly” sound what would be removed by the opus codec. This is what normally lives in the shadows of your music.
Experiment with the resolution knob to find the most interesting components.
Tweak the eq curve to extract and boost the good stuff.
Turn off delta listen and enjoy the result.
