apUnmask 是一款音频插件，它 利用心理声学技术，挖掘隐藏的音频信息，并重新利用有损压缩

。该插件旨在放大音频中被其他成分以心理声学方式掩蔽的部分。为了实现这一目标，apUnmask 使用了 Opus 高品质音频压缩编解码器的部分检测算法。它会提取那些会被压缩消除的信号成分。这些成分通常由于在时间和频率上被更响亮的成分所掩盖而无法被听到。apUnmask 能够放大并雕琢这些被掩蔽的内容，并将其添加到音乐中。为了塑造提取信号的频率，它会经过一个线性相位图形均衡器。该均衡器采用贝塞尔曲线平滑频率响应，且不会出现过冲。最终呈现出一种超逼真的音频效果。该过程有助于听众同时听到音乐的更多细节。apUnmask 可以用作母带处理效果器，也可以用作单个乐器的智能激励器。利用音频压缩改善音质：通常，有损音频压缩只是简单地移除某些信息。数十年的研究催生了巧妙的算法，能够检测出哪些信息可以在不被听者察觉的情况下被移除——这一切都是为了节省数据量。借助 apUnmask，您可以利用这项研究成果，提取并放大这些信号，帮助听者听到更多细节。建议工作流程

• 在主轨道或要增强的单个轨道上插入 apUnmask。
• 调整主增益，直到可以看到合理的信号变化量。
• 切换“增量监听”按钮，即可听到会被 Opus 编解码器移除的“幽灵般”的声音。这通常是隐藏在你音乐深处的音符。
• 尝试调整分辨率旋钮，找出最有趣的组件。
• 调整均衡曲线，提取并增强有效成分。
• 关闭增量监听，享受结果吧。

Psychoacoustic mastering plugin, uncover hidden audio, repurpose lossy compression

Overview
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.

Improving Sound Using Audio Compression
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. With apUnmask, you can use this research power to your benefit, extracting and amplifying those signals to help the listener’s ears 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.
