Playing back using a SourceDataLine Use a SourceDataLine (javax.sound.sampled.SourceDataLine) when you want to play a long sound file which cannot be pre-loaded into memory or to stream real-time sound data such as playing sound back as it’s being captured. Advantages:
LiveData Overview Part of Android Jetpack. LiveData is an observable data holder class. Unlike a regular observable, LiveData is lifecycle-aware, meaning it respects the lifecycle of other app components, such as activities, fragments, or services. 2. Recuva for Android.
start (); for (Note n : Note.values()) { … A SourceDataLine object can accept a stream of audio data and push that audio data into a mixer in real time. The actual audio data can derive from a variety of sources, such as an audio file, (which will be the case in this program) a network connection, or a buffer in memory. Confusing terminology I created a game framework sometime ago to work on Android and Desktop, the desktop part that handle sound maybe can be used (LineUnavailableException e) { e.printStackTrace(); } } private SourceDataLine getLine(AudioFormat audioFormat) throws LineUnavailableException { SourceDataLine res = null; DataLine.Info info = new For a SourceDataLine or a Clip, just substitute that class for TargetDataLine as the class of the line variable, and also in the first argument to the DataLine.Info constructor. For a Port, you can use static instances of Port.Info, in code like the following: Android: Windows: macOS: Ubuntu: OS Version: 8.0+ 10+ 10.12.6 + Latest LTS: JRE Version-7+ 7+ 7+ Architectures: arm32: arm64: x86: x86: x64: x64: x64: Media Flow: sendrecv: sendrecv: sendrecv: sendrecv: sendrecv: sendrecv: sendrecv: Audio Codecs PCMU 2018-08-01 The line is not yet opened with a specific format.
I started off with sending the live audio between two android devices to confirm my method was correct.
Info dataLineInfo = new DataLine.Info(SourceDataLine.class, audioFormat); SourceDataLine sourceDataLineTemp = (SourceDataLine)AudioSystem.
open (af, 4096); line. start (); line. write (buffer, 0, buffer.length); line. drain (); line.
public void run() { byte[] buffer = SoftAudioPusher.this.buffer; AudioInputStream ais = SoftAudioPusher.this.ais; SourceDataLine sourceDataLine = SoftAudioPusher.this.sourceDataLine; try { while (active) { // Read from audio source int count = ais.read(buffer); if(count < 0) break; // Write byte buffer to source output sourceDataLine.write(buffer, 0, count); } } catch (IOException e) { active = false; //e.printStackTrace(); } }
These methods offer better consistency across devices, and the methods make it easier for users to manage their media collections. I wrote the following code that works fine. But I think it only works with .wav format.. public static synchronized void playSound(final String url) { new Thread(new Runnable() { // The wrapper thread is unnecessary, unless it blocks on the // Clip finishing; see comments.
I'm currently trying to stream live microphone audio from an Android device to a Java program. I started off with sending the live audio between two android devices to confirm my method was correct. The audio could be heard perfectly with barely any delay on the receiving device. Minimum supported version (OS, framework, browser, etc) is affected by the vendor support policy. Where a vendor deprecates support for a particular product version we will do our best to maintain support, but we cannot guarantee that these versions will be fully functional and no further performance optimizations will be performed.

For a SourceDataLine or a Clip, just substitute that class for TargetDataLine as the class of the line variable, and also in the first argument to the DataLine.Info constructor. For a Port , you can use static instances of Port.Info , in code like the following:

我有一个android Activity ，它连接到java类并以套接字的形式向其发送数据包。全类会接收声音数据包，然后将其丢给PC扬声器。 It also demonstrates how to perform token-based authentication, and how to send and display a chat message. To build the example, load the project in an appropriate IDE. For C#, use Visual Studio; for Java/Android use either IntelliJ or Android Studio; and for iOS/macOS, use Xcode.

Applications that play or mix audio should write data to the source data line quickly enough to keep the buffer from underflowing (emptying), which could cause discontinuities in the audio that are perceived as clicks. public void run() { byte[] buffer = SoftAudioPusher.this.buffer; AudioInputStream ais = SoftAudioPusher.this.ais; SourceDataLine sourceDataLine = SoftAudioPusher.this.sourceDataLine; try { while (active) { // Read from audio source int count = ais.read(buffer); if(count < 0) break; // Write byte buffer to source output sourceDataLine.write(buffer, 0, count); } } catch (IOException e) { active = false; //e.printStackTrace(); } } Be aware that when you run an Android app: you don't run/compile it on a standard JVM/JDK, you don't even execute java bytecode.
