Abstract
National folk music has different styles, has extremely strong regional and national characteristics, and has a high cultural and artistic value. It carries the profound connotation of national culture. Music has non-semantic symbolicity and strong ambiguity, which makes the related research topics of music signals more challenging than speech signals. With the rapid increase of the number of digital music, due to the complexity of music itself, the ambiguity of the definition of the category of music and the limitation of the understanding of the characteristics of human auditory perception, Therefore, the analysis of the characteristics of folk music is a prerequisite for realizing the rapid and effective retrieval of folk music resources, and plays an important role in audio signal processing. However, there are few studies on the classification and information extraction of folk music. The article is based on the St-EN and St-ZCR feature extraction of the three styles of music in Aze, Le, and playing and singing in Amdo Tibetan folk music. Three kinds of musical styles have adopted a time-domain analysis is briefly analyzed Amdo Tibetan folk music signal, by extracting signal features music, We can find short-term energy than the short-time average zero-crossing rate of all types of music more clearly reflect the unique characteristics of the signal.

The melody was euphemistic and passionate. It can be seen from figure 3 that the music signal of "playing and singing " has a certain change law but different from "Aze", the treble duration is balanced with the bass duration, and it can be clearly seen that the high and low pitch are faster and the rhythm is more cheerful, short, crisp; The short-term energy is the same as "Le", there is a maximum amplitude point, and there is a clear law of increase and decrease; short-term average zero-crossing rate is basically consistent with "Le", the previous period changes smoothly but relatively scattered in the late stage, there is a high-pitched change in the middle; the short-time autocorrelation function is basically close to the sinusoidal curve, and the periodicity is strong
All three music styles adopt the time-domain analysis method to intercept a frame of music signal and add Windows for analysis
Summary
National folk music is a cultural product of a nation, produced under years of living labor and different environments. Tibetan folk music is diverse and rich in content. [1] It expresses the production, labor, and character traits of Tibetan people and shows the unique social culture of Tibetan areas in a colorful and unique tone. Due to the unique natural ecology and human history of the Tibetan community, the Tibetan traditional music reflects diversity and integrity, regardless of its artistic features or social functions. Tibetan traditional music can be divided into three types: folk music, religious music, and court music. Folk music is the most important part of Tibetan traditional music, and it is the most widely distributed, the most diverse and the most abundant.
