## 5 Experimental Results  
### An Overview of the Dataset  
This section provides an overview of the Manchu music dataset, including detailed statistics and analyses of the number of recordings, duration, and diversity. These details not only offer fundamental data for experiments but also provide important references for evaluating the dataset's quality and exploring its application potential. The specific situation is shown in Table 4.  
The Manchu music dataset includes audio recordings from multiple categories, covering various forms such as traditional instrumental solos, folk ensembles, and singing.  
The dataset contains a total of 5000 recordings. The recordings are classified into five main categories: traditional instrumental solos; folk ensembles; folk songs; festival music; and religious ritual music. These recordings encompass the main types of Manchu music, ensuring the dataset's representativeness and diversity.  
To fully assess the dataset's scale and coverage, we have compiled the total and average duration of recordings in each category. The total duration of the recordings in the dataset is 500 h (average duration of 6 min per recording). These data indicate a relatively even distribution of recording durations, providing sufficient sample sizes for model training and evaluation.
