This is the two pieces of code I used, output audio and capture audio. The socket in the constructor is used to accept audio data from the network. Do not do network audio can remove it. I hope to share our experience with you. 8-) Import java.io.*; Import javax.sound.sampled.*; Import java.net.*; /** * Title:voicechat

. HTTP Live Streaming HTTP Live streaming is an HTTP-based streaming media transport protocol proposed by Apple. It cuts an entire audio and video stream into a small audio and video stream that can be downloaded by HTTP and generates a playlist (m3u8), where the client only needs to get a m3u8 playlist of resources to play the audio and video. Can realize live

Introduction Audio and video are the main methods for multimedia applications to provide information to users. These audio and video data generally have a high sampling rate, and the compressed raw data has practical value, otherwise, it will not only occupy a large amount of storage space, but also have a low validity rate during playback or network transmission. Therefore,

1 PCM InterfaceFor different digital audio subsystem, there are several interfaces between microprocessor or DSP and audio devices for digital conversion. The simplest audio interface is the PCM (Pulse coded modulation) interface, which consists of a clock pulse (BCLK), a Frame sync signal (FS), and a receive data (DR) and send data (DX). At the rising edge of th

-party recording software on a computer, you can select the recording format and sound source to truly implement custom recording. Generally, mobile phone and computer recording can only record sound in a fixed format;3. After the recording software is enabled, modify the sound format and change the sound source to "system sound only", and change the storage location accordingly, you can set it according to your convenience;4. There will be a floating window on the computer, opening the video to

Many users upgrade to the WIN8 system, the operation interface and prior to the XP, Win7 very different, for some novice if there are some glitches, do not know how to solve the problem. For example, a recent user said Win8 prompted "audio device problem, there is one or more audio services are not running," How to solve this situation? The following small series to share some solutions for everyone, intere
