asp.net创建MP3波形图像 [英] asp.net create waveform image from mp3

问题描述

我要寻找一种方式来创建上传到服务器mp3文件的图形波形。从一个小小的研究我beleive的MP3需要转换为原始格式第一...但我对如何创建波形为.gif格式此声音文件不知道。

I am looking for a way to create a graphical waveform of mp3 files uploaded to a server. From a little research i beleive the mp3 would need converting to a raw format first...but i have no idea on how to create a .gif format of the waveform for this sound file.

90％的声音文件是长度超过60分钟。

90% of the sound files would be over 60 minutes in length.

据我了解，这将无法完成它上传之后，它需要被放入队列并进行处理。

I understand this wouldn't be able to done right after it is uploaded, it would need to be placed into a queue and processed.

我已经看了几个libaries如跛，但没有似乎能够达到我所期待的。

I have looked at several libaries such as lame, but none seem to be able to achieve what i am looking for.

任何指针到正确的方向将是极大的AP preciated！

Any pointers into the right direction would be greatly appreciated!

非常感谢你！

推荐答案

您可能会发现 FMOD 或的 BASS 能为你做到这一点，很容易。我相信FMOD下载带有一个可视化的例子，这样你就可以从该推断。他们无论是在MP3的读取并进行必要的计算。

You may find FMOD or BASS can do this for you, quite easily. I believe the FMOD download comes with a visualisation example, so you can extrapolate from that. They both read in MP3's and perform the necessary calculations.
