offlineAudioCtx.addEventListener("complete", () => {
console.log("Offline audio processing now complete");
alert("Song processed and ready to play");
playBtn.disabled = false;
});
You can also set up the event handler using the oncomplete property:
const offlineAudioCtx = new OfflineAudioContext();
offlineAudioCtx.oncomplete = () => {
console.log("Offline audio processing now complete");
alert("Song processed and ready to play");
playBtn.disabled = false;
};
