Problems solved by technology

However, conventional digital audio and video players are based on listening to the sound and pressing the keyboard, which is very dependent on the sound. Often, the operation cannot be performed after the sound is played. Since the sound does not leave traces, the playback is very blind. It is difficult to accurately grasp the starting point and end point of playback during normal playback. It is very troublesome, sometimes even impossible, to selectively play and repeat playback and audio editing operations. Obviously, it cannot satisfy users' work, life, entertainment and learning. needs

Abstract

The invention relates to an audio and video player and method. A storage module is used for storing an audio file and a video file; a control module is used for reading the audio file and / or video file according to a touch control instruction of a touch control display module and decoding the audio file and video file; a waveform conversion module is used for extracting an audio from the decoded audio file and / or video file and converting the audio into an oscillogram with playing time; the touch control display module is used for generating the touch control instruction and transmitting the touch control instruction to the control module, and is also used for displaying the oscillogram and a decoded video, and according to the oscillogram, adjusting and controlling the rate of process of audio and video playing and selecting and editing the audio file and / or video file. Compared with the prior art, the audio and video player provided by the invention can convert the audio into the oscillogram, and can adjust and control of the rate of progress of playing and edit the audio file and video file according to the oscillogram, is visual in operation, and is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of players, in particular to an audio and video player and its method. Background technique [0002] With the development of technology, digital audio has replaced tape audio. However, conventional digital audio and video players are based on listening to the sound and pressing the keyboard, which is very dependent on the sound. Often, the operation cannot be performed after the sound is played. Since the sound does not leave traces, the playback is very blind. It is difficult to accurately grasp the starting point and end point of playback during normal playback. It is very troublesome, sometimes even impossible, to selectively play and repeat playback and audio editing operations. Obviously, it cannot satisfy users' work, life, entertainment and learning. needs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an audio and video player and met...
