This would only be usefull in a mode and options that will create the file. If a WAV file is being created, the type parameter can be used to create a PCM Wave file or a G.723.1 Wave file by using #WaveType enum# The #PChannel::IsOpen()# function may be used after object construction to determine if the file was successfully opened.
