// 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().
