Detailed Description

This class is similar to the PWavFile class found in the PWlib components library. However, it will tranparently convert all data to/from PCM format, allowing applications to be unconcerned with the underlying data format. Note that this will only work with sample-based formats that can be converted to/from PCM data, such as uLaw and aLaw

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.

Parameters:

mode	Mode in which to open the file.
opts	OpenOptions enum# for open operation.
format	Type of WAV File to create
