From the developer:
AACelerator is the quickest way to easily encode all of your audio files into MPEG-4 Advanced Audio Codec (AAC) audio files. This new encoding format included in QuickTime 6 represents a significant step forward in encoded file size and sonic quality. By all accounts, audio encoded at the same bit rates as MP3 files will result in audio files with superior sonic quality.
