Auditory evoked potentials (AEPs) include the auditory brainstem response (ABR), middle latency response (MLR), and cortical auditory evoked potentials (CAEPs), each one covering a specific latency range and frequency band. For this reason, ABR, MLR, and CAEP are usually recorded separately using different protocols. This article proposes a procedure providing a latency-dependent filtering and down-sampling of the AEP responses. This way, each AEP component is appropriately filtered, according to its latency, and the complete auditory pathway response is conveniently represented (with the minimum number of samples, i.e., without unnecessary redundancies). The compact representation of the complete response facilitates a comprehensive analysis of the evoked potentials (keeping the natural continuity related to the neural activity transmission along the auditory pathway), which provides a new perspective in the design and analysis of AEP experiments. Additionally, the proposed compact representation reduces the storage or transmission requirements when large databases are manipulated for clinical or research purposes. The analysis of the AEP responses shows that a compact representation with 40 samples/decade (around 120 samples) is enough for accurately representing the response of the complete auditory pathway and provides appropriate latency-dependent filtering. MatLab/Octave code implementing the proposed procedure is included in the supplementary materials.

依赖于延迟的过滤和完整听觉通路反应的紧凑表示。

听觉诱发电位（AEP）包括听觉脑干反应（ABR），中潜伏期反应（MLR）和皮质听觉诱发电位（CAEP），每一个都涵盖特定的潜伏范围和频带。因此，通常使用不同的协议分别记录ABR，MLR和CAEP。本文提出了一种过程，该过程提供了与延迟相关的AEP响应过滤和下采样。这样，根据每个AEP组件的等待时间对其进行了适当的过滤，可以方便地表示完整的听觉通路响应（具有最少数量的样本，即没有不必要的冗余）。完整响应的紧凑表示有助于对诱发电位进行全面分析（保持与沿听觉途径的神经活动传递相关的自然连续性），这为AEP实验的设计和分析提供了新的视角。另外，当为临床或研究目的而操纵大型数据库时，所提出的紧凑表示减少了存储或传输的需求。AEP响应的分析表明，每十年10个样本（约120个样本）的紧凑表示足以准确表示完整听觉通路的响应，并提供适当的依赖于延迟的过滤。中号 当为临床或研究目的而操纵大型数据库时，所提出的紧凑表示减少了存储或传输的需求。对AEP响应的分析表明，每十年有40个样本（大约120个样本）的紧凑表示足以准确表示完整的听觉通路的响应并提供适当的依赖于延迟的过滤。中号 当为临床或研究目的而操纵大型数据库时，所提出的紧凑表示减少了存储或传输的需求。AEP响应的分析表明，每十年10个样本（约120个样本）的紧凑表示足以准确表示完整听觉通路的响应，并提供适当的依赖于延迟的过滤。中号在L ab / Octave代码中，执行建议的过程的步骤包括在补充材料中。
