            audioCxt.decodeAudioData(result as ArrayBuffer, (buffer) => {
                var audioClip = new cc.AudioClip();
                audioClip['_setRawAsset']('', true);
                audioClip['_nativeAsset'] = buffer;
                audioClip.url = '';
                cc.audioEngine.playEffect(audioClip, loop);
            });
        });
