Summary
Render audio data.
Syntax
[DllImport(DLL, EntryPoint = "openmpt_module_read_quad")]
public static extern int ModuleReadQuad(IntPtr mod, int sampleRate, int count, short[] left, short[] right, short[] rearLeft, short[] rearRight)Remarks
The output buffers are only written to up to the returned number of elements.
You can freely switch between any of the "openmpt_module_read*" variants if you see a need to do so. libopenmpt tries to introduce as little switching annoyances as possible. Normally, you would only use a single one of these functions for rendering a particular module.
It is recommended to use the floating point API because of the greater dynamic range and no implied clipping.
