+
+// 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().
