 # Dataset Card for Chinese Traditional Instrument Sound
-The raw dataset is sourced from the [Chinese Traditional Instrument Sound](https://ccmusic-database.github.io/en/database/ctis.html), which contains recordings from over 200 types of Chinese traditional instruments, modified Chinese musical instruments, and instruments from ethnic minority groups. Notably, some of these instruments are rarely encountered by the majority of the Chinese populace.

-Based on the aforementioned raw dataset, after data processing, we have constructed the `default subset` of the current integrated version of the dataset, and its data structure can be viewed in the [viewer](https://www.modelscope.cn/datasets/ccmusic-database/CTIS/dataPeview). As the dataset has been cited and used in published articles, the step of further constructing the `eval subset` for evaluation has been omitted. This dataset is intended for retrieval tasks, hence no further splits have been made, and currently, there is only one split, which is the training set (train).
