Keyboard security problems and hazardsWith various hacker technologies, hackers can remotely control the installation of keyboard recording programs on users' computers. These tools, known as keyboard recorders, can record all information that users enter from the keyboard. As hacking technologies are increasingly open to the public, even beginners can easily use these tools, resulting in greater harm to users. Once the user's computer is installed with a keyboard
The project needs to use the Baidu voice interface in the web to achieve speech recognition, the use of such a technical solution, but the implementation encountered a lot of problems, found that most of the online articles are only in detail the official example samples provided, the actual development did not provide any valuable advice, and recorder.js is not directly suitable for the voice interface of Baidu AI, so this article will be developed in the details of the record with this, welcom
Nbsp; I am the administrator of a small and medium-sized Linux website. The system architecture is RHEL4.0 + PHP4.3 + Mysql4.03 + Apache1.23. The average daily IP access volume is 200, a typical small Linux website. Because it is a small website, there is no cost to use a tape drive for system backup, using a DVD disc recorder + network hard disk. With the increasing application of Linux, especially in terms of network applications, there are a large
% had washing machines, and 2‰ had refrigerators. Fortunately, Japan's economy began to develop rapidly since the middle of 1950s. Double-digit GDP growth and low inflation rates have greatly boosted consumer spending. Many people said that the real post-war period in Japan started in 1955, and that year we invested the first transistor radio into the Japanese market. The country's GNP grew rapidly, with a growth rate of 10.8%. Japanese households needed every kind of goods, and at that time the

AMR bought a new video game "Guess Your-out!". The goal of the game is to find a exit from the maze so looks like a perfect binary tree of height h. The player is initially standing at the root of the tree and the exit from the tree was located at some leaf node.Let's index all the leaf nodes from the left of the right from 1 to 2H. The exit is located at some node n where 1≤ n ≤2H, the player doesn ' t know wher E The exit is so he had to guess

Linux compile ffmpeg and convert MP3 to AMRAMR format is a popular audio file format on smartphones, such as MP3 format, but the file is smaller than MP3, so it is widely used in mobile internet projects. At the end of last year to assist Lenovo Research Institute to develop a pre-installed product process needs to use the MP3 format and AMR format of mutual conversion, the server environment is CentOS 6.0, the process is as follows.1. First install t
discussing the system architecture, let's take a look at the current situation of audio encoding. Currently, there are many Audio Encoding formats, including PCM, ADPCM, DM, PWM, WMA, Ogg, Amr, ACC, mp3pro, and MP3; for human speech has LPC, CELP and ACELP; other MPEG-2, MPEG-4, H. 264, VC-1 audio and video program encoding format. For more information about the market trend of mobile multimedia formats, see Figure 1 ).

HD Voice, also known as wideband Voice, is an audio technology that transmits HD, natural voice quality to cellular, mobile, and wireless headsets. Compared with traditional narrowband telephones, HD voice improves voice quality to a large extent and reduces the hearing burden.All networks and devices on the communications industry chain need to support HD voice to demonstrate the benefits of this technology. by June 2011, 20 Cellular networks operating in 18 countries, as well as 33 leading mob
3gp file Presumably everyone will not be unfamiliar, because in the functional machine era 3gp almost dominate the function machine video platform, then 3gp what is it? How does the 3gp file open?
What file is 3gp?
3GP is a simplified version of the MP4 format, which reduces storage space and low bandwidth requirements, allowing limited storage space on the phone to be used. 3GP supports multiple types of video files (part 2nd of MPEG-4, based on H.263, MPEG-410) and multiple aud

The recorder class is responsible for implementing all functions of soundrecorder. It contains a mediarecorder member and a mediaplayer member, and encapsulates the operations related to these two members. This class provides a series of interfaces to the soundrecorder class to control the recording and playing process. The following describes important members and methods.
