PHP Windows environment can convert AMR format to MP3 format ask the great God for advice Reply content: PHP Windows environment can convert AMR format to MP3 format ask the great God for advice PHP is not good at this thing, even if it can be written, but also slow to dieThis kind of thing or a C or something to fix it, you can first a class library through PHP calls, but also better to use Gearman

in ms. The minimum unit of the voice frame is 20 m. The data size for every 20 ms is 320 bytes. Of course, this is 16 bit, 8 kHz. How to calculate it. Okay. Let's talk about the encoding and deepen your understanding of this aspect: After the 320-byte PCM-16 speech is encoded, the programming length is 13 bytes, that is, the voice format of AMR Nb. If we want to play it through audiotrack, we have to use amrdecoder to decode and restore these 13 b

Codeforces Amr and Chemistry (Mathematics + chaos) Question: give n numbers. Each number can be multiplied by two or divided by two (the downward integer is equivalent to the left or right shift). Ask how many operations can make the n numbers disguised. Idea: first consider the possible values of each number, and express a number in the form of s * 2 ^ k. s is an odd number. Then all values of this number may be s '* 2 ^ x, (s' = s/2, (s/2)/2 ,.....)

Codeforces 558C Amr and Chemistry rules Question Link Question: Given n-long sequence You can select a number to make it * = 2 or/= 2. Ask how many operations are performed to make all numbers equal. Ideas: For each number, calculate the number that can be changed to and the minimum number of steps. Cnt [I] indicates that the number of cnt in the sequence can be changed to I Step [I] indicates the cost and the amount of I that can be changed to I. Not

Title Link: Http://codeforces.com/problemset/problem/558/BTitle meaning: Give a sequence, and then find the most occurrences, but the interval occupies the shortest interval around the value.Because it is a side-read-in-edge comparison, the most critical issue is to record where each number first appears, that is, the left value. Because you want to ensure that the number of occurrences is the most, you need a cnt[] array to record the number of occurrences. Then, when the maximum number of occu

Test instructions: The number of n, each can be multiplied by two or divided by two (rounding down equivalent to left or right), ask at least how many operations can make this n number disguised.Idea: First of all consider the possible value of each number, a number is represented as s*2^k form, S is odd.Then all possible values for this number are S ' *2^x, (S ' =s/2, (S/2)/2,.....) and S ' *2^xBecause the data range is small, and each value may not be a maximum of hundreds of, so record 1 to 1

CodeForces 558C Amr and Chemistry (bitwise operation, number theory, rule, enumeration), codeforces558c Codeforces 558C Question: give n numbers. You can perform two operations on each number: num * 2 and num/2 (rounded down: the minimum number of operations required to make n equal. Analysis: Calculates the binary common prefix of each number. The enumeration method is also supported. /**Author : Flint_x *Created Time : 2015-07-22 12:33:11 *File nam

This is a simple script I wrote in Perl to convert between AMR AND DIFERENT audio formats (WAV, Midi MP3 ). my script has this input/output digoal :. -----------. --> | mid/mod | '----- + -----' | timidity | V v. ---------.. -------------.. -------.. -----------.. -------. | + -- mp123-> | + -- encode-> | + -- ifs2amr-> | MP3 | WAV | http://xa.bi/mms/

Objective The previous article has shared with you the asp.net use of the seven-cow conversion method will be. Amr mp3 method, at that time also said that there is another way to use the FFmpeg conversion method, the following article will give you a detailed description of this method. This method is much simpler than the first. FFmpeg's name comes from the MPEG video coding standard, the front "FF" represents "Fast Forward", and FFmpeg is a set of

Today, I helped my friend get a computer from a wholesaler. the built-in system is Linux, so I helped myself to build the first system, but it was always a blue screen during decompression, so I thought there was a problem with the machine. I used the employee to say that this function was restricted and only Windows 7 could be installed. Only Windows 7 systems could use the independent video card,Curiosity is stirred up, and then the human flesh begins to break the casserole and find the founda

The complete program that can run on R600 consists of two parts: a program that runs on the host (CPU), a program running on the R600 processor, part of the program called the shader program when processing graphics applications, and a program called Kernel when the GPU is used for general computing.Figure 1This section is all from the AMD manual "R600 instruction Set Architecture".2.
