The last time I briefly introduced the use of AudioRecord and AudioTrack, this time I used SurfaceView to implement an Android mobile phone analog signal oscilloscope (PS: I have also talked about the mobile phone oscilloscope OF THE j2_version before ). Recently, the Internet of Things has become very popular. As mobile phone software developers, how can they co

The previous simple introduction of the Android program in the development of the use of Audiorecord and Audiotrack, this time combined with Surfaceview to achieve an Android version of the phone analog signal oscilloscope. Recently the Internet of Things is very hot, as a mobile phone software developers, how to do not modify the phone hardware circuit under the

Oscilloscope is in the university when the teacher taught, but out of work has not been used, and gradually forget, and now learn again. Look at the effect chart: Here is a custom histogram, and then there is a button, click the button, where the pillars will keep moving, similar to the music player in the oscilloscope beat.

Zookeeper Let's take a look at the program running in this article (the screen recording speed is slow, and the real machine runs more smoothly ): In this article, the program uses the 8000hz sampling rate, which requires a high real-time performance for the x-axis drawing. If the resolution of the x-axis is not reduced, the program's real-time performance is poor. Therefore, the program reduces the x-axis data range by 8 times ~ 16 times. Because the 16-bit sampling is used, the height of th
