Android audio and video goes deep into an AudioRecord recording to generate pcm into wav (with source code download), androidaudiorecord
This project address is named AudioRecord recording (can be paused, convert pch to wav ).Https://github.com/979451341/Audio-and-video-learning-materialsHere is an official description1. AndioRecord Overview
The main function of the AndioRecord class is to allow various JAV
The source code of video recording seems to be quite a lot on the Internet. Here I declare that I copied the source code from others and modified it to optimize it. I am a little tired. I will not talk about it anymore. paste the source code directly:
VaR server_uri: String = "rtmp: // 215.102.25.xx/gdrc/video ";// The FMS address, which is the same as that set for the player.
VaR videoname: String = "record"; // specifies the
Android mediarecorder allows you to pause resumable recording.
I recently studied the mediarecorder recording function and found that after the pause, I continue recording. I have little online reference information. Now I will share my learning achievements with you:
The basic principle is as follows: mediarecorder uses mic
TelephonyManager.CALL_STATE_OFFHOOK:recordCall ()//start recording break;
When the case telephonymanager.call_state_ringing:log.e ("Jereh", "Caller number is:" + incomingnumber);
If the number belongs to the blacklist if (Incomingnumber.equals ("123456")) {//If it is a blacklist, shield Stopcall ();
} break;
}
}
};
/** * Stop Recording * * private void Stoprecord () {if (
Under pressure, I studied red5 and as3 last night and found it quite interesting.Red5 and fms are both good things, and they find learning things very fast under pressure. The code is as follows:Copy code // Pre-defined statementImport mx. utils. Delegate;// Create a basic network connection objectVar nc: NetConnection = new NetConnection ();// Connect to the local Red5 serverNc. connect ("rtmp: // localhost/online ");// Pass the nc that has established a connection with the red5 s
Mediarecorder enables recording and recording.

When using mediarecorder for recording videos, you must strictly abide by the function call sequence in the API instructions. Otherwise, the video cannot be executed successfully.
The following is an example o
The Microphone access class provided by Windows Phone is Microsoft. Xna. Framework. Audio. Microphone, which belongs to the XNA Framework. This class is also required to access the Windows Phone Microphone in Silverlight. Therefore, you must add a reference to Microsoft. Xna. Framework.1. Declare local variables to obtain the microphone Singleton.

output channels. Almost all mobile phone systems, such as Windows, Symbian, and palm, support this function. Android does not support this function, but it is not technically impossible. It should be due to insufficient requirement analysis during system design.
The HTC diamond hardware is almost the same as hero hardware. Unlike the system, diamond can call recording, which means it is not a hardware problem.

I have encountered many problems when I am studying Android development these two days. Now I will record the mediarecorder () recording for my reference only ~~
Very convenient and simple ~~

The following describes the basic usage of the recording interface provided in Android.
Here we will list several important usage methods, whic
IOS recording and playing: A few amazing demands
In a recent project, you need to connect the iPhone with a microphone (Apple is called Headset, and without a microphone is called Headphone), and then synchronize the recording and play. After this function is implemented, you need to change the Input Source for recording and playing.
