FideliQuest的FiDef®是一种专为音频工程师设计的极低振幅心理声学刺激。它使接受性大脑放松，更密切地关注传入的音频刺激。在使用功能性神经成像技术的脑生理学实验室测试中，FiDef已被证明可以激发与感知和注意力相关的大脑活动，并增强听力和参与的主观过程。
FiDef工艺由FideliQuest LLC在美国开发，最初由MAAT授权用于我们的thEQblue。现在，相同的算法可以独立用于所有主要的插件格式，包括适用于macOS的VST 2、VST 3和AAX原生格式，以及适用于macOS和Windows的音频单元。FiDef是一款获得专利的64位音频处理器，与众不同。脑科学在这种潜意识信号发生器中处于领先地位，它迫使听众全神贯注……参与其中！
探索
自爱迪生发明第一个蜡筒以来，音频捕获和播放的历史可以概括为对一个看似不可能的目标的技术追求：逼真地复制实际的聆听体验……数字技术的出现在解决模拟录音和播放中固有的许多问题的同时，也带来了其他挑战。与此同时，DXD（数字极限定义）和MQA（主质量认证）等新的支持格式，以及消费者对未压缩HRA或高分辨率音频音乐目录的趋势，为家庭带来了新的保真度。然而，即使是最高保真度的数字播放仍然表现出一定程度的保留，使音乐保持在一定距离，并不总是让它拥抱和感动我们。无论是低保真度还是高保真度，模拟还是数字，FiDef都能带来更深层次、更令人满意的连接。
FiDef® by FideliQuest is a very low amplitude psychoacoustic stimulus designed specifically for audio engineers. It makes a receptive brain relax and pay closer attention to an incoming audio stimulus. In brain physiology laboratory tests using functional neuroimaging techniques, FiDef has proven to excite brain activity related to perception and attention, and to enhance the subjective processes of listening and engagement.
The FiDef process, developed in the US by FideliQuest LLC, was first licensed by MAAT for our thEQblue. That same algorithm is now available standalone for all major plug-in formats, including VST 2, VST 3 and AAX native for macOS and Windows plus Audio Units for macOS. FiDef is a patented, 64 bit audio processor like no other. Brain science takes the lead in this subconscious signal generator that compels the listening to lean in and…engage!
The Quest
Since Edison's first wax cylinders, the history of audio capture and playback can be summarized as the increasingly technical pursuit of a seemingly impossible goal: lifelike replication of the actual listening experience…The advent of digital technology, while solving many of the problems inherent in analog recording and playback, brought with it other challenges. At the same time, new enabling formats such as DXD (Digital eXtreme Definition) and MQA (Master Quality Authenticated), along with consumer trends toward uncompressed HRA or High Resolution Audio releases of music catalogs have brought new levels of fidelity to the home. Yet, even the highest fidelity digital playback still exhibits a level of reserve that keeps the music at arm's length, not always allowing it to embrace and move us. Low fidelity or hi–fi, analog or digital, FiDef makes for a deeper, more satisfying connection. |
