Remarks
Converts the given sound file, stored in RAW format, using the sound encoding format defined inside the EncodeFormats.FormatToUse property..
A conversion session can be stopped at any time through a call to the ConvertFileCancel method.
For converting a specific range within the sound file you can use the ConvertFileRawRange method.
During the conversion phase, a few effects, like Normalization and DC Offset removal, may be applied through the ConvertFileDestEffectsSet method and a few options may be set through the ConvertFileDestOptionsSet and through the ConvertFileDestResamplingSet methods.
A successful call to this method will fire the ConvertSoundFileStarted event followed by a number of ConvertSoundFilePerc events and finally by the ConvertSoundFileDone event.
