在MIDI表示中，中C（钢琴）的正确八度音程值是多少？ [英] What is the proper octave value of Middle C (Piano) , in MIDI representation?

问题描述

我目前正在用C＃开发一个光学音乐手稿阅读应用程序。对于音符识别场景，我发现需要知道每个键的八度值。



由于重新发布了音符，例如：4C4 where（Duration ）（注）（八度）是represntation的顺序。



因此可以熟悉MIDI交互的人（或者之前已经做过这种解释的人） ），帮助我。 （仅考虑高音谱号）



哪个八度为中间C，用MIDI表示法？

下图中C的八度音阶是什么？

提前谢谢。

I am currently developing a Optical Music Manuscript Reading application in C#. For the note identifcation scenario, I have find out the need of knowing the octave values for each key.

Because of represnting thie note as in example: 4C4 where (Duration)(Note)(Octave) is the order of represntation.

Therefore can someone who is familiar with MIDI interaction (or anyone who have done this sort of an interpretation earlier), help me with this. (Considering the Treble Clef only)

In which octave is middle C, in MIDI notation?

In which octave is the C in the below image is?

Thank you in advance.

推荐答案

这是MIDI音符＃60：

此外，您可以执行以下操作：1）使用任何MIDI库，它允许您发送至少基本的MIDI信息并编写能够发送您选择的音符的代码，这样您就可以在这里; 2）使用一些具有八度音符和音符的已知作业的乐器听取问题中的音符;如果你没有，找一些软件键盘;你可以找到一些这样的程序; 3）使用你的代码，选择一个音调相同的音符。



这个食谱不需要绝对音高能力，小于由绝大多数人口拥有的平均听觉技能将足以解决这个问题。



你的第二个问题是冗余的;答案可以从第一个问题的答案中推断出来。

This is the MIDI note #60:

Besides, you could do the following: 1) take any MIDI library which allows you to send at least basic MIDI messages and write code capable of sending notes of your choice, so you could here them; 2) listen to the note in questioni using some musical instrument with known assignments of octaves and notes; if you don't have any, find some software keyboard; you would be able to find a number of such programs; 3) using your code, select a note which sound at the same pitch.

This recipe does not require absolute pitch ability, less than average aural skills which is owned by the absolute majority of population would be more than enough to solve this problem.

And your second question is redundant; the answer can be inferred from the answer to your first question.
