** ****************************
|

**
|
||||
** How to use:
|
||||
** - libsndfile.dll must have already been compiled and be in this
|
||||
** application's search path
|
||||
**
|
||||
** - You must edit this file to point to the file you want to convert. Set
|
||||
** the following line of code (found in the Main() function further below)
|
||||
** to the name of a .WAV file that exists on your system.
|
||||
** 186: string sfn = "input.wav";
|
||||
**
|
||||
** - From a command prompt type
|
||||
** csc generate.cs
|
||||
**
|
||||
** - Run the resulting executable 'generate.exe'
|
||||
**
|
||||
**
|
||||
** Note: You will obviously need the csc compiler and the .NET runtime. I think
|
||||
** these are freely available for download from Microsoft's website
|
||||
** (part of the .NET SDK?).
