mic

Based on Android 4.4 and 4.2, codec used for detection is wm8994. The mic detection in Android and Kernel is based on the headset detection. The specific process is as follows: 1) kernel uses Jack to detect pin interruption and detects that headphones are inserted. 2) read the codec register to determine whether the headset has mic 3) notify the Android upper layer through the InputEvent/UEvent Mechanism Fo

Recently, to do distributed development on the mic cluster, there are two modes that can be used:1) Offload mode: This mode is similar to the GPGPU programming idea, which transfers the high-parallelism code to the local mic processor, and the other code is still executed on the CPU. The mic is only responsible for local computing, and distributed communication m

TI's Development Board uses the aic23b audio decoding chip, which has two input ports, mic in and line in. Now we use the sharc 21479 version of Adi, which uses the 1939 chip of Adi, but 1939 does not provide mic in and line in input differentiation. However, the audio port of the Development Board can only receive linear input, the mic in cannot be received, whi

Android provides the audiorecord and mediarecorder functions for recording. audiorecord is an audio stream that reads MIC data and can analyze stream data while recording; mediarecorder can directly store the MIC data to a file and encode the data (such as AMR and MP3 ). First, add your application to the permission (whether you are using audiorecord or mediarecorder ): Then, we will introduce the usage of

Mic:the maximal information coefficient is a standard for judging the degree of concentration of data using grid division method. MIC is based on the idea that if there is a relationship between the 2 variables, then there should be a way to draw a grid on the scatter plots of those variables, so that most of the data points are concentrated in several cells of the grid. By searching for this "best fit" grid, the computer calculates t

Mic is a method used to calculate the correlation between variables in a large data set, which is effective: no assumptions are made on the distribution of data, and the correlations between variables (both linear and nonlinear) are estimated Download the compressed file in the link below and unzip it to compile: http://pan.baidu.com/s/1bSEG2a 1.

Today, let me talk about Kabbah and mic. Kabbah, McAfee, and Norton are the three major targets in the world. They are absolutely unambiguous. So what is the comparison between Kabbah and coffee? No one can tell who is strong or weak. Many people have asked whether Kabbah or maimai is the answer. You can use whatever you like. It's like comparing your girlfriend with your buddy's girlfriend. They're pretty, but who they like. ==== --- But it is stil

When using ssh-v, the Unspecified GSS failure error occurs. This is mainly caused by the use of the GSSAPI authentication function. This is also the reason if you encounter a slow use of scp. Let's continue. 1. Fault# M
