用Java创建音频频谱分析器 [英] Creation of Audio Specrum Analyzer in java

问题描述

Hi Friends

请帮助我了解逐步创建Java频谱分析仪的方法.在这里，我确切需要的是有一个音频文件作为输入，并具有该音频文件的频谱.我没有找到任何方向如何实现这一目标.

Hi Friends

Please help me in knowing the step by step approach to create an audio spectrum analyzer in java. Here what I need exactly is to have an audio file as input and have a spectrum for that audio file. I am not finding any direction how to proceed to achieve this. specify me the right direction to start with.

推荐答案

您需要做的是对文件的音频输出(位流)执行快速傅立叶变换.一些有用的搜索:

What you need to do is perform a Fast Fourier Transform on the audio output (bitstream) of the file. A few helpful searches:

0.研究-输入是什么，输出是什么?
1.理解力-这个项目应该实现什么?
2.设计-您将如何实现目标?
3.实施-谁来编写代码?
4.测试-您如何知道结果正确?

以上将解决任何问题.剩下的将需要一个关于您遇到的特定问题的更具体的问题.

祝你好运.

0. Research - what are the inputs, what are the outputs?
1. Comprehension - what is this project supposed to achieve?
2. Design - how will you achieve the goal?
3. Implimentation - who will write the code?
4. Testing - how will you know the results are correct?

The above will work for any problem. The rest will require amore specific question regarding specific problems you encounter.

Good luck.
