隨著現代電腦科技的進步，自動測量音腔中每一個時間點的音律值，已經不再是個難題，這對於音腔的定量研究，可是具有重大的意義。惟在進行測音中，若沒有思考諸如在那一個時間點為音準點的問題時，則接下來關於律學的研究，都可能會變得有所困難。換言之，在無法確定測音方法是否周延的情形下，想要由此來說明音律之間的律制關係時，其結果只是將音律變化的情形簡單化而已。　文透過對以往測音方法的檢視，重新思考在做音律之測音研究時，所會面臨的諸多問題，進而探討音準點測定的可行性。

　　With the advancement of modern computer technology, to automatically detect the tonality of a specific point in yinqiang is no longer an arduous task. This is a significant breakthrough in quantitative research of yinqiang. However, when doing pitch detection, if questions such as which point is the accurately determined pitch, the following study on temperament can become difficult. In other words, in the case when it is unable to determine whether the pitch detection method will only result in simplification of the variation of tonality. This study attempts to reconsider various problems that may occur when doing pitch detection of tonality by reviewing the pitch detection methods applied in the past, so as to explore the feasibility in determining the accurate pitch.
