如何从头开始创建声音C＃

Question

I am trying to build a virtual piano in C#, and want a way to create a scale of musical notes from scratch.

I know that I can simply find or create a bunch of .wav files, 1 for each note, but this will create too much space on the User's Hard disk and not be very intuative for myself in the future.

So is there a way to create a proper sound - eg B flat, in C# without using a .wav file, all in code thorugh c#, and if not, is there a way to do this in a different language - C++.

Thanks, I have tried to make it as clear as possible.

Answer 1

I think this looks like it should get you started:

EDIT : I should add that generating sounds without .wav samples and emulating a piano are at odds with each other.

If you want to get a 'real' piano sound, it's best to work with samples (hold them in memory if you don't want to keep them in the filesystem). If you just want a simple way of emitting accurate notes (which sound nothing like a real piano) then doing it programmatically is the way to go!

Answer 2

If you want to emulate a piano specifically you only have two options, one of which is to use samples and the other is physical modelling . Physical modelling requires some pretty advanced knowledge of DSP (filtering, convolution, etc.) and a piano would be a challenging instrument to tackle but it has been done by the likes of Pianoteq

On the subject of samples, to create a piano that is anywhere near a convincing analogue you would ideally require more than one sample per note for different velocities with crossfades between them but you can probably get away with using a sample over a limited range of notes to reduce the total number of samples.

Answer 3

You might want to take a look at MIDI.

There's a windows API you could wrap in C++, then expose a managed interface you can consume in C#.

Answer 4

Maybe using a MIDI library could help? I'm not into the matter, but if you don't want to use audio files it's the only thing that comes to my mind. There's a question about it here .
