Supplementary material for 'Developing the hertz art-science project to allow inaudible sounds of the Earth and Cosmos to be experienced'

This repositary contains a sample audio clip that has been produced by using an infrasound signal from the Aurora Borealis to manipulate pink noise. In the hertz project this output has been low pass filtered to 120Hz for the hertz playback equipment. It has been low pass filtered at 400Hz here so it is audible through a standard laptop speaker. The video was a clip from a trial development session of the hertz project featuring Juliet Robson.

本仓库包含一段采样音频片段，该片段通过使用北极光（Aurora Borealis）的次声信号调制粉红噪声制作而成。在赫兹项目（Hertz Project）中，该输出音频已针对项目的播放设备做了低通滤波至120赫兹的处理；而在此处，我们将其低通滤波至400赫兹，使其可通过标准笔记本电脑扬声器播放。本仓库附带的视频片段取自赫兹项目的某次试开发环节，出镜者为朱丽叶·罗布森（Juliet Robson）。
