APU 响度压缩器是一款压缩器/扩展器,旨在支持现代响度类型(LUFS、True Peak)。 结果是压缩器听起来更加透明。 该压缩机还能够以更传统的方式运行,使用 RMS 和峰值测量单位,因此您可以鱼与熊掌兼得。 有关 RMS/Peak 和 LUFS 之间差异的更多信息,您可以查看我的 LUFS 博客文章。

启用“学习”模式后,压缩器将自动调整源或目标范围以匹配源材料。 这是开始使用压缩器的好方法,并且可以用作进一步微调的起点。

默认情况下,压缩器使用“源范围”和“目标范围”代替阈值+比率控制进行操作。 如果您愿意,您还可以启用传统的阈值+比率控制。 位于压缩器动态部分右上角的下拉菜单允许在这些操作模式和其他操作模式(例如扩展器、限制器等)之间切换。

您可以免费试用压缩机; 它会自动开始 30 天的试用。 不需要用户名,并且试用没有任何限制。


The APU Loudness Compressor is a compressor/expander designed to support modern loudness types (LUFS, True Peak). The result is a compressor which sounds more transparent. The compressor is also capable of operating in a more traditional manner, using RMS and Peak units of measurement, so you can have your cake and eat it too. For more information on the differences between RMS/Peak and LUFS, you can review my LUFS blog post.

With “learn” mode enabled, the compressor will automatically adjust the source or target range to match the source material. This can be a great way to get started with the compressor and can be used as a starting point for further fine-tuning.

By default, the compressor operates using a “source range” and “target range” in place of threshold + ratio controls. You can also enable the traditional threshold + ratio controls if you prefer. A drop-down menu located at the top-right of the compressor’s dynamics section allows switching between these modes of operation and others, such as expander, limiter, etc.

You can try out the compressor for free; it’ll automatically start a 30-day trial. No username is required, and the trial comes without limitations.

Check it out to see if it fits into your workflow. If you have any questions or feedback, don’t hesitate to reach out using the “Contact the Developer” beacon on this website.
