This sample demonstrates how to use the Sound Converter to transcode a Movies Sound Track from one audio encoding format to another. It uses Standard Compression to configure the audio compressor and creates a QuickTime Movie containing the newly encoded Sound Track. It also demonstrates the preferred way to use the Sound Converter - using SoundConverterFillBuffer - and shows what you need to do to support VBR compression formats - in QuickTime 6, an example is the AAC format, part of MPEG4 audio support. This Sample will also work with any audio file format QuickTime can import as a Movie such as AIFF, WAVE and MP3.
