preloading the next song in a playlist a bit before the current one ends

问题

I've made a small media player that works fine but I want to make it so that there's no more loading in between each songs

I know about the preload property but it only preloads the music when the page loads for the first time, so I feel like this wont work

is there a way to do this at all? maybe using the web audio API?

回答1:

When you start playing a song you could watch the play event of the audio and already start preloading the next song in the queue.

This is the function I use for preloading audio, you can use it any time, not only in the first time the page being loaded:

function preloadAudio (filename) {

    var sound = new Audio();
    sound.preload = 'auto';

    sound.addEventListener('canplaythrough', function () {
        // now the audio is ready to play through
    });

    document.body.appendChild(sound);

    sound.src = filename;
    sound.load();

}
