// Class: WaveFileWriter
// Description: Simple utility class to make it easy to write long 16-bit stereo
// audio streams to disk.
// Use Start() to start recording to a file, and AddStereoSamples to add wave data.
// The float variant will convert from -1.0-1.0 range and clamp.
// Alternatively, AddSamplesBE for big endian wave data.
// If Stop is not called when it destructs, the destructor will call Stop().
