声音可视化器，用于分析声谱 [英] Sound visualizer that analyzes sound spectrum

问题描述

我看了很久，但似乎找不到任何答案.我已经在After Effects上完成了一些工作，但是还没有完成，所以我认为自己编程是最好的.事实是，我不知道怎么办.

我想要一个可视化器来分析输入声音的频谱，并通过制作与特定频率范围相关联的图像(根据其分析的声音水平)来对其作出响应.

我有种感觉，这是一个很大的问题，在这个地方，我敢肯定是这样，但是我自己几乎没有对任何事情进行编码的介绍.我猜到现在为止，我一直在使用预制的模板".感谢任何可以提供帮助的人.

I''ve looked for a long time, but I can''t seem to find any answer. I''ve accomplished something on After Effects, but it''s not cutting it, so I''m thinking programming it myself would be the best. Thing is, I have no idea how.

I want to have a visualizer that analyzes the spectrum of the input sound and responds to it by making an image that''s associated with the certain frequency range jump (according to the level of the sound it''s analyzing).

I have a feeling that this is a HUGE derp of a question, and in this place, I bet it is, but I''ve barely been introduced to coding anything myself. Up until now, I guess, I''ve been using premade "templates." Thanks to anyone who can help.

推荐答案

请参阅我对问题的评论.

由于您未指定平台，计算机语言，活动目标，要求和其他特定细节，因此答案只能与该问题一样笼统.

看这里:

此外，您确实需要以下领域的基础知识:
http://en.wikipedia.org/wiki/Spectrum_analysis [ http://en.wikipedia.org/wiki/Fourier_analysis [ http://en.wikipedia.org/wiki/Fourier_transform [ http://en.wikipedia.org/wiki/Fast_Fourier_transform [ http://en.wikipedia.org/wiki/WAV [ http://en.wikipedia.org/wiki/Sound_file_format [

Please see my comment to the question.

As you did not specify platform, computer language, the goal of your activity, requirements and other specific detail, the answer could only be as general as this question.

Look here:
http://bit.ly/yUbLV1[^],
http://bit.ly/yzoyMk[^].

Besides, you really need fundamental knowledge in the following fields:
http://en.wikipedia.org/wiki/Spectrum_analysis[^],
http://en.wikipedia.org/wiki/Fourier_analysis[^],
http://en.wikipedia.org/wiki/Fourier_transform[^],
http://en.wikipedia.org/wiki/Fast_Fourier_transform[^],
http://en.wikipedia.org/wiki/WAV[^],
http://en.wikipedia.org/wiki/Sound_file_format[^].
