This project address, name is Audiorecord recording (can pause, convert PCH to WAV), for starHttps://github.com/979451341/Audio-and-video-learning-materialsFirst, the official description.1.AndioRecord Approximate descriptionThe main function of the Andiorecord class is to enable various Java applications to manage audio resources so that they can record sound collected by sound-related hardware. The implementation of this feature is accomplished by "

This article describes the Java read WAV file (waveform file) and the method of drawing waveform diagram. Share to everyone for your reference. Specifically as follows: Because a lot of netizens recently asked me about the waveform file reading and writing problems, in order to make everyone more convenient and let the code can get better improvements, I will this part (waveform file read and write) code open source in the GitHub above. The address

Usually we watch the concert video or MV Everything is RMVB format, but want to listen to the phone in the song and can not see how to do, to know mobile phone watch video is not backstage, you return to the desktop it will be turned off, so we want to convert the format, turn to WAV or other audio format. Below I teach you how to turn the RMVB format to WAV format. The first step, we first put the video f

tedious step. The required software cool Edit Pro or Sound Forge These two are more practical. Cool Edit Pro is only introduced here, the latter is also very convenient, like people can try their own. "The proposal does not use the Chinese, because after the Chinese, will have the software use the bug" Run cool Edit Pro software, open the sound source, where the general use of WAV or standard MP3 (note: Non-standard MP3 open, will appear a dialog box

WAV is a lossless sound file under Windows, the file holds the audio PCM information and the player plays that music when most information is made, he has two blocks, the first block is the format block, the second block is the data blockFirst, the format block, the format block with a picture can be explained, as followsUsing Winhex to analyze a WAV audio file, Han Lei's farewell message is as followsBy co

value is the number of channels × the data bit value per sample/8. The playback software needs to process multiple bytes of data of this value at a time to adjust the value for the buffer zone. 22 h 2 　 The number of data digits of each sample, indicating the number of data digits of each sample in each channel. If multiple channels exist, the sample size is the same for each channel. 24 h 4 Char DATA tag "data" 28 h

Another product of the company, when monitoring CTI, the recording format is PCM.To play in IE, You need to convert it into a standard WAV. previously, I used a com library for conversion. Now I can't use that library for various reasons (64-bit support is not good), So I implemented it in Java. The basic code is as follows.In fact, WAV is only a PCM file with the relevant file header and description inform

Problem You want to have a method for playing sound quickly. Solution In xna3.0, you can directly load and play sounds from xNa without loading them using xact. Although this method removes some advanced xact functions, it makes playing sound very easy. Working Principle First, add a sound file to the project. The method is the same as adding an image to the project. For more information, see tutorial 3-1. The simplest solution is to drag a .wav fi
