I need to play some music in html5 by using audio tag. The data is a base64 string(data:audio/wav;base64,xxxxxx) which is generated by the server. Like image tag,it is said that audio tag can also use the data url,so I tried this:

But I failed,nothing happened. I searched for the result and find this:

Play audio using base64 data in html5

There is a data url in the answer and I tried it,it played well.

So I think my base64 data is wrong,but when I put the data url into the browser address bar．It is played by some plugin!!Just the same performance like below(worked well but need to use a plugin):

So my question is: what is the difference between the two ways?

I think there maybe some file header that should be contained when using audio tag,but I am not sure about it.

I find this link where the guy use the header template(RIFF<##>WAVEfmt \x10\x00\x00\x00\x01\x00\x01\x00<##><##>\x02\x00\x10\x00data<##>"):

Playing audio from data:url google chrome mobile

Appreciate for any help,thanks in advance.

EDIT Oh,so sorry to find out that most browsers do not support for the audio/midi data type,the object tag can play it because the plugin is more powerful. And I found a midi.js here:

您的 mimetype (?) 似乎是 audio/midi 而不是 audio/wav。它也取决于浏览器。我使用了相同类型的代码，只是我将音频/wav (*.wav) 转换为 Base64。使用音频/wav 和 Base64 转换的（http://www.motobit.com/util/base64-decoder-encoder.asp）数据我可以播放音频。

在 HTML5 中也无法识别自动缓冲，这可能是我测试的 VS 2013 Express for web 的怪癖。我拿了一个扩展名为 *.wav 的音频文件并将其转换为 Base64 并将其插入您的代码（使用音频/wav），它在 Mozilla Firefox 中播放良好。

以下是 IE 11、Safari 5.1.7 和 Mozilla 26.0 显示带有音频标签的页面的方式：

http://hodentek.blogspot.com/2014/03/internet-explorer-11-cannot-play-audio.html

这是转换为 Base64 并返回的代码： http ://www.aspfree.com/c/a/vb-net/encodingdecoding-web-service-web-service-provider/
