Objective I believe you all know it,. amr format for mobile device audio, compression compared to larger, more for the voice, call, the effect is OK! So, the mobile device uses AMR format to record and save more! A more common example: Call recording, micro-letter voice and recording, etc.! But this ghost, in two words to describe, is "egg pain", because HTML5 does not support it (

Asp.net ...amr .mp3 (using ffmpeg conversion method),. amrffmpeg Preface In the previous article, I learned how to use asp.netto convert .amrto using the seven-way conversion method. At that time, I also said that another method is to use the ffmpeg conversion method. The following article will introduce this method in detail. This method is much simpler than the first one! The name of FFmpeg comes from the MPEG video encoding standard. The previous "

Recently, it seems to be working with the voice!The second method of audio conversion, this method is more simple than the first way!First, you need to download a "Ffmpeg.exe" plugin and put it in your project, such as:The file is called in the program to help convert the audio format!On the code:usingSystem;usingSystem.Threading;usingSystem.IO;usingSystem.Diagnostics;usingsystem.security; Public Partial classcowala_201512chritmas_amrtest:system.web.ui.page{protected voidPage_Load (Objectsender,

First, what is AMR file? AMR (Audio/modem Riser, Voice/modem card) is an open industry standard that defines an expansion card that can support both sound and modem functions. This kind of design can effectively reduce the cost and simultaneously solve some limitations on the function of voice and modem subsystem. AMR (full name is Adaptibve multi-rate), in add

Recently to do a project, to the mobile phone app on the file upload to the server, including pictures, sounds, video files. At first only the Android version, as you know, Android's recording format Amr, can not play out on the computer, must be transcoding. Because previously only the Android version, so the use of Jave to facilitate the solution. But then the iphone version was added and the recording format was CAF. Jave supports dozens of audio a

Test instructionsn number, each time you can choose a number to make it *=2 or/=2Ask at least how many times the operation makes all the numbers equal.Ideas:For each number, calculate the number that the number can be converted to, and the smallest number of steps to change to, save with two arraysCnt[i] indicates that the number of CNT in a sequence can be changed to IStep[i] The number of those that can become I is the cost of I and how much.Which, when encountered odd times to special treatme

how many times 2. Of course, the direct calculation can also be divided by 2 until the base value equals Base[j]. But the outer layer has already used the N*log (n) complexity, so here we divide the number of times divided by 2 by 2 points. A maximum of 10W can be divided by 16 times 2. So the complexity of the dichotomy is log2 (16) = 4 is almost equal to O (1). This can be done because, if I divide by 2^k and the base value is smaller than base[j], then dividing by a value greater than 2^k wi
