FiDef采用了高度专业化的专利过程来创建与源音频紧密相关的自定义噪声配置文件。噪声层是可听见的，但是FiDef利用一种现象，该现象利用了大脑利用亚听见的噪声来增强声音解释的能力。

噪声层还可以经受住有损格式的编码过程，从而确保上传到流行的流媒体服务的混音保留了全分辨率信号源的声音特征。

FiDef employs a highly specialized, patented process to create a custom noise profile that is tightly correlated to the source audio. The noise layer is sub-audible, but FiDef makes use of a phenomena that exploits the brain’s ability to make use of sub-audible noise to enhance the interpretation of sound.

The noise layer also survives the encoding process to lossy formats, ensuring mixes uploaded to popular streaming services retain the sonic characteristics of the full resolution source.
