-Firstly, **Fig. 1** illustrates the number and proportion of audio clips in each category. The Plucks category accounts for a significantly larger proportion than all other categories, comprising 74.88% of the dataset. The category with the smallest proportion is Tremolo, which accounts for only 0.49%, resulting in a difference of 74.39% between the largest and smallest categories. Moving to **Fig. 2**, which presents the audio duration of each category. The total duration of Plucks audio is also significantly longer than all other categories, with a total duration of 117.77 minutes. In contrast, the category with the shortest total duration is Glissando, with only 1.13 minutes. This differs from the pie chart, where the smallest category was Tremolo. The difference between the longest and shortest durations is 116.64 minutes. From both the pie chart and the duration chart, it is evident that this dataset suffers from a severe data imbalance problem. In the end, **Fig. 3** gives the audio clip number across various duration intervals. Most of the audio clips are concentrated in the 34-1004 milliseconds duration range, accounting for approximately 85% of the dataset. Beyond 1974 milliseconds, the number of audio clips drops sharply.
+In this part, we present statistics at label level. The number of audio clips is equivalent to the count of either onset or offset occurrences. The duration of an audio clip is determined by calculating the offset time minus the onset time. At this level, the average audio duration is 0.62 seconds, with the shortest being 0.03 seconds and the longest 6.82 seconds. Firstly, **Fig. 1** illustrates the number and proportion of audio clips in each category. The *Plucks* category accounts for a significantly larger proportion than all other categories, comprising 74.88% of the dataset. The category with the smallest proportion is *Tremolo*, which accounts for only 0.49%, resulting in a difference of 74.39% between the largest and smallest categories. Next, **Fig. 2** presents the audio duration of each category. The total duration of *Plucks* audio is also significantly longer than all other categories, with a total duration of 117.77 minutes. In contrast, the category with the shortest total duration is *Glissando*, with only 1.13 minutes. This differs from the pie chart, where the smallest category was *Tremolo*. The difference between the longest and shortest durations is 116.64 minutes. From both the pie chart and the duration chart, it is evident that this dataset suffers from a severe data imbalance problem. In the end, **Fig. 3** gives the audio clip number across various duration intervals. Most of the audio clips are concentrated in the 34-1004 millisecond range. Among them, 8,660 audio clips fall within the 34-519 millisecond range, 4,935 clips fall within the 519-1004 millisecond range, and only 2,243 clips exceed 1004 milliseconds in length.
