  # Dataset Card for Guzheng Technique 99 Dataset
18
- The raw dataset, sourced from [Guzheng_Tech99](https://ccmusic-database.github.io/en/database/csmtd.html#Tech99), encompasses 99 solo compositions for the guzheng, recorded by professional musicians in a studio environment, with a cumulative duration of 9,064.6 seconds. Each composition has been annotated for every note, indicating the onset, offset, pitch, and playing techniques, which include chanyin, boxian, shanghua, xiahua, huazhi\guazou\lianmo\liantuo, yaozhi, and dianyin. This meticulous annotation has resulted in a total of 63,352 annotated labels across the dataset.

- Based on the above raw data, we performed data processing and constructed the `default subset` of the current integrated version of the dataset, and the details of its data structure can be viewed through the [viewer](https://www.modelscope.cn/datasets/ccmusic-database/Guzheng_Tech99/dataPeview).

- In light of the fact that the current dataset has been referenced and evaluated in a published article, we transcribe here the details of the dataset processing during the evaluation in the said article: each audio clip is a 3-second segment sampled at 44,100Hz, which is then converted into a log Constant-Q Transform (CQT) spectrogram. A CQT accompanied by a label constitutes a single data entry, forming the first and second columns, respectively. The CQT is a 3-dimensional array with dimensions of 88×258×1, representing the frequency-time structure of the audio. The label, on the other hand, is a 2-dimensional array with dimensions of 7×258, indicating the presence of seven distinct techniques across each time frame. Ultimately, given that the raw dataset has already been divided into train, valid, and test sets, we have integrated the feature extraction method mentioned in this article's evaluation process into the API, thereby constructing the `eval subset`.
