hi it is my first time here ..iam making a project with c# but i need some help so please try to help me
i want a c# program that saving an audio and another program that opening it

[WillemM]

I know it is possible to encode/decode audiofiles in C#.
The only way I know until now is complex. Try to find out how mp3 for examples is encoded/decoded, and make your own methods of doing this.
