Data used during the 'Introduction to experimentation' final project: Bepaling van de snelheid gedurende een eenparig rechtlijnige beweging middels het Dopplereffect.

Full unedited recordings used for the determination of the velocity of a moving source with constant speed, as well as the edited videos, converted WAV files and edited WAV audio files used for data analysis.<br>Audio is either marked as cut, corresponding to the raw audio conversion from the trimmed videos, or as data_collection, corresponding to the edited audio files from which the data used for the analysis was extracted.<br>Videos are either only marked by the used frequency, velocity and distance, corresponding to the full unedited videos, or as cut, corresponding to the videos trimmed from the starting point to the endpoint used in the analysis.<br>The initially obtained csv and xls diles from the Phyphox app are also published, for completeness. This data wasn't used for further analysis however, due to it's unreliability.<br>Furthermore, the data analysis performed in Python has been attached as an .ipynb file.<br>Finally, individual plots of the obtained data, with its corresponding uncertainty, have been uploaded as .pdf files. These plots also contain the fitted theoretical function, as a grey dotted line.<br><br>

本数据集包含用于测定匀速运动声源速度的完整未编辑录音，以及用于数据分析的编辑后视频、转换得到的WAV格式音频文件与编辑后的WAV音频文件。<br>音频文件分为两类：标记为cut的文件对应从剪辑视频中直接提取的原始音频转换产物；标记为data_collection的文件则为提取了分析所用数据的编辑后音频文件。<br>视频文件同样分为两类：仅标注实验所用频率、速度与距离的为完整未编辑原始视频；标记为cut的则是从起始点裁剪至分析所需终点的剪辑后视频。<br>为保证数据完整性，本数据集同时发布了从Phyphox应用中导出的原始csv与xls格式文件，但由于其可靠性不足，并未用于后续数据分析。<br>此外，本次数据分析所用的Python脚本已以.ipynb格式文件附加提供。<br>最后，所得数据的各独立绘图附带对应不确定度，已以.pdf格式文件上传，这些绘图同时包含以灰色虚线呈现的拟合理论函数。
