Accompanying Materials to Smith et al (2026) "Eavesdropping with Distributed Acoustic Sensing: Audio and Speech Detection on Fibre-optic Cables"

This notebook accompanies the manuscript 'Eavesdropping with Distributed Acoustic Sensing: Audio and Speech Detection on Fibre-optic Cables' by Smith et al. (2026). It provides minimal code (ManuscriptAccompaniment.ipynb) to access and visualise parts of the data acquired and analysed in the study. The audio segments provided are in .npy format and are 120 seconds long at their respective sampling frequencies, as denoted in their filenames. They begin with some frequency chirps and tones, before transitioning to the speech segments that were the focus of the study. The original audio used in playback tests is also provided as a .wav file.本笔记本配套Smith等人（2026）发表的学术论文《分布式声学传感（Distributed Acoustic Sensing）窃听：光纤电缆（Fibre-optic Cables）上的音频与语音检测》。本笔记本提供极简代码（ManuscriptAccompaniment.ipynb），用于访问并可视化本研究中采集与分析的部分数据集。本次提供的音频片段格式为.npy，单段时长均为120秒，采样频率如文件名所示。片段开头包含若干频率啁啾信号与单音信号，随后过渡至本研究重点关注的语音片段。本研究回放测试所用的原始音频亦以.wav格式提供。
