AudioPlayer is an add-on for Vaadin that uses WebAudio to allow streaming playback of an arbitrary server-side PCM data buffer. Audio can be transported as WAV. It also supports server-side control of the audio playback such as audio and stereo balance, as well as advanced control via pluggable effects, such as highpass and lowpass filters.

Demo

Includes demo application that shows examples of most functionality including:

  • streaming different types of audio files
  • creating UI that connects to the audio player
  • server-side control of audio player
  • creating effect chains with pluggable effects

Installing

For more information about using the addon and/or running the demo application, see the README.md file or visit the github page: https://github.com/drewharvey/VaadinAudioPlayer

Sample code

        String filename = "somefile.wav";
        String filepath = "src/main/resources/org/vaadin/addon/audio/wav";
        // decodeToPcm method found in demo
        ByteBuffer fileBytes = decodeToPcm(filename, filepath);

        // createWaveStream method found in demo
        Stream stream = createWaveStream(fileBytes, new WaveEncoder());

        AudioPlayer player = new AudioPlayer(stream);

        // hook play button to AudioPlayer
        Button playButton = new Button("Play");
        playButton.addClickListener(buttonClickEvent -> {
            if (player.isStopped()) {
                player.play();
            } else if (player.isPaused()) {
                player.resume();
