pcm-player

A refined pcm player for web, automatically handles AudioContext-resume to be able to play sound, and provides friendly API for users.

How to use

const player = new FUPCMPlayer({
    encoding: '16bitInt',  // 8bitInt16bitInt 32bitInt 32bitFloat
    channels: 1,           
    sampleRate: 16000,     
});

player.feed(pcmData)  // pcmData is a typedArray carrying pcm data with specified encoding

player.destroy();     // recycle anthing allocated by the player

After data is fed into the player, it will be scheduled to be played automatically. On the air you can continuously feed pcm stream in.

Other API

player.setRequestStop(); // stop playing after current pcm-segmengt is consumed

player.setOnEnd(callback);  // callback will be triggered when stop-request is fulfilled

player.interrupt();      // stop playing immediatedly

player.getTimestamp();   // get elapsed time against first bit played, especially useful when the player is used as a audio-clock

player.volume(someVolume)
