Embodiment Construction

[0042] see figure 1 and figure 2 Concrete implementation process of the present invention is as follows:

[0043] The present invention is mainly realized by an oscilloscope object, which can realize functions including audio file display, recording, and voice audition. in

[0044] (1) Data source:

[0045] The range of data sources should be as wide as possible, and the object should be able to identify file data types, memory block data, and voice data. The file data type is passed in the full path of the file, and then the content of the entire file is read.

[0046] An in-memory data store with audio data passed in when in-memory block data. Voice data is the data obtained by sampling the sound card in real time during recording.

[0047] (2) Reading of file data type:

[0048] First use the extension of the file to distinguish the media type. When encountering an unrecognizable file, for example, if there is no extension or the extension does not match its actual me...
