apulSoft apUnmask，apulSoft 出品心理声学母带插件。借鉴 Opus 有损音频编码的检测算法，提取出音频里被强信号心理声学掩蔽、平时难以听见的隐藏细节，放大塑形之后叠加回原信号，实现超写实的听觉效果，既可用于母带总线，也可作为智能激励器作用于单轨乐器。
原理：有损压缩会识别并剔除被掩蔽的微弱细节；apUnmask 反向利用这套检测逻辑，把本该被删掉的 “幽灵信号” 提取出来加以利用。
核心功能
‑ Delta 信号监听：一键单独预览被算法识别出的掩蔽细节，直观听到原本被掩盖的音频成分。 ‑ 线性相位图形均衡器：对提取出的细节信号做频率塑形，贝塞尔曲线平滑，无增益过冲。 ‑ Gain 总增益、Resolution 分辨率旋钮，控制提取信号的强度与检测粒度。 ‑ 44.1kHz 采样率下延迟为3128 采样点。 ‑ 全部操作支持无限撤销 / 重做。 ‑ XML 格式预设，跨平台、跨宿主导入导出；明暗两套 UI，支持自定义配色。
推荐工作流程
- 插入到母带轨道或需要增强的单轨；
- 调节 Gain 增益，直到界面能看到合理的 Delta 信号；
- 开启 Delta Listen，聆听被提取的隐藏细节；
- 调整 Resolution 找到有价值的音频成分；
- 绘制 EQ 曲线，筛选、放大想要的细节频段；
- 关闭 Delta Listen，得到处理完成的音频。

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.
System Requirements: Windows 10 or newer running on an x64 CPU with AVX.
