Android sound focus ---- adjust the volume of Music from Music back to Luncher Sound types are defined in the AudioSystem. java file. /* The default audio stream */public static final int STREAM_DEFAULT = -1;/* The audio stream for phone calls */public static final int STREAM_VOICE_CALL = 0;/* The audio stream for system sounds */public static final int STREAM_S

of mediarecorder, and call mediarecorder. getmaxamplder () through a thread (); The obtained is the maximum instantaneous amplitude, which is expressed by multiplying the logarithm by 10. Finally, it should be noted that the hardware customized by Android mobile phone manufacturers is different, so the value obtained by MIC can only be "characterized", and cannot be taken as the real basis. Although they are smart phones, they are still mobile phones

firstThe main device that provides BCLK and Lrck clocks.1, in the left alignment mode, the MSB can be in the bclk of the first rising edge of the following LRCLK transition.2. In right-justified mode, the LSB can transition before the last rising edge of the BCLK LRCLK.3. In i2s mode, the MSB can transition from the second rising edge of the BCLK following the lrclk of a transition.4, some sound cards also support the DSP format, the format is not pa

; Normally in the audio and video interface to adjust the volume of the stream is Stream_music, back to luncher adjust is stream_voice_call, but this switch a little delay streamoverride.sdelayms, resulting in the exit tone, After the video interface is adjusted immediately, the change is still the size of the Stream_music:You can modify the/frameworks/base/media/java/android/media/audioservice.java file /*

a deep understanding of this thing ?) It is unlikely that the JB audio system can be understood based on the evolution of things. Therefore, it is recommended that the students who have never seen the evolution history of audio be carefully studied in the 99% S. (in the past, I only recommended that you take a look at it. Now the requirement for improvement is carefully studied) an in-depth understanding of Android volume I audio system. BTW, in a sp

;java : java new 50000s waste 56ms c++ : c++ new 50000s waste 338ms java : java new 100000s waste 60ms c++ : c++ new 100000s waste 687ms The result shows that the new object in C + + is 10 times times slower than Java. But in terms of time. Assume that you are simply new to a Java object in C + +. The time gap of several microseconds is completely negligible.Maybe someone will say. C + + is so much slower because it is findclass,getmethodid every time. These two values are not changed duri
