如何阅读在C＃中的MIDI文件？ [英] How to read MIDI file in C#?
问题描述
你知道在C＃中的图书馆，我可以为了用它来读取现有的* .MID文件？我想提请MIDI文件的声音频率曲线图，但我不能得到的内部数据。我试着用n音讯和Alvas.Audio，但我wans't能够读取的MIDI文件。任何建议
Do you know any library in C# that I can use in order to read an existing *.mid file? I want to draw the sound frequency graph for the MIDI file, but I cannot get the inner data. I tried using NAudio and Alvas.Audio, but I wans't able to read a MIDI file. Any suggestions?
推荐答案
的MIDI文件格式比较复杂（见这里）。写他们比阅读他们（与WAV文件）更容易。我不知道这样做的任何C＃库，但我要指出，因为你的最终目标是创建一个光谱仪，你也许并不需要一个图书馆阅读的MIDI文件的。
The MIDI file format is relatively complicated (see here). Writing them is easier than reading them (as with WAV files). I don't know of any C# libraries that do this, but I should mention that since your ultimate goal is to create a spectrograph, you probably don't need a library to read the MIDI file at all.
MIDI文件不包含任何实际的音频信息 - 它只是包含了一个合成器，如指示注意，邮件，音量增减等mesages为了从一个MIDI文件创建一个光谱仪，你需要让你得到实际的音频数据运行FFT分析了玩它的东西。
A MIDI file does not contain any actual audio information - it merely contains instructions for a synthesizer, e.g. note on messages, volume change mesages etc. In order to create a spectrograph from a MIDI file, you need to "play" it with something so that you get actual audio data to run FFT analyses on.
您并不真正需要的东西打它，当然。谷歌 MIDI到WAV 为自动转换MIDI文件转换成WAV文件的选项的负荷。一旦你的WAV文件，谷歌 wav文件的频谱分析仪C＃来查看生成的WAV文件数据光谱仪的许多选项。
You don't really need to play it with something, of course. Google midi-to-wav for a load of options for automatically converting MIDI files into WAV files. Once you have the WAV files, Google wav file spectrum analyzer c# to see the many options for generating spectrographs from WAV file data.
要向下选民：谷歌暗示的关键字作为一个答案是不会自动坏事。在这种情况下，我只是想STEAR在正确的方向的提问者，让他们不花时间做一些他们并不需要做什么。
To the down-voters: suggesting Google keywords as an answer is not automatically a bad thing. In this case, I'm just trying to stear the asker in the right direction, so that they don't spend time doing something they don't need to do.
