Example 20 with File

use of com.codename1.io.File in project CodenameOne by codenameone.

the class AudioBufferSample method lowLevelUsageSample.

private void lowLevelUsageSample() {
    // Step 1: Create your audio buffer
    // This can be any size you like really.
    int bufferSize = 256;
    // Audio buffer path
    String path = "mybuffer.pcm";
    // Can be any string, as it doesn't correspond
    // to a real file.  It is just used internally
    // to identify audio buffers.
    AudioBuffer audioBuffer = MediaManager.getAudioBuffer(path, true, bufferSize);
    float[] myFloatBuffer = new float[bufferSize];
    // This float array will be used to copy data out of the audioBuffer
    // Step 2: Add callback to audio buffer
    audioBuffer.addCallback(floatSamples -> {
        // This callback will be called whenever the contents of the data buffer
        // are changed.
        // This is your "net" to grab the raw PCM samples.
        // floatSamples is a float[] array with the PCM samples. Each sample
        // ranges from -1 to 1.
        // IMPORTANT!: This callback is not run on the EDT.  It is called
        // on an internal audio capture thread.
        audioBuffer.copyTo(myFloatBuffer);
    // All of the new PCM data in in the myFloatBuffer array
    // Do what you like with it - send it to a server, save it to a file,
    // etc...
    });
    // Step 3: Create a MediaRecorder
    MediaRecorderBuilder mrb = new MediaRecorderBuilder().path(path).redirectToAudioBuffer(true);
    try {
        Media recorder = MediaManager.createMediaRecorder(mrb);
        // This actually starts recording.
        recorder.play();
        // Record for 5 seconds... use a timer to stop the recorder after that
