"AC3Tools Pro is the complete toolkit to encode, split or decode AC3 files."

AC3Tools Pro is the complete professional suite for AC3 files processing. With AC3Tools Pro, you can remaster AC3s, translate and recompose sound-tracks to DivX/XViD movies, compose several WAV PCM-files into 5.1 AC3-file. AC3Tools Pro includes AC3 Decoder, AC3 Demuxer, and AC3 Encoder. AC3 Decoder processes multi-channel AC3-file into two-channel MP3, WMA, WAV or Ogg Vorbis files. The algorithm used in AC3 Decoder splits audio channels to achieve surrounding effect as if you were listening to original AC3 file at 5.1 audio system. According to Dolby Laboratories’ recommendations, the number of profiles built in AC3 Decoder contains both Dolby Prologic and Dolby Prologic II profiles. The conversion results in a two-channel audio-file that can be splitted by hardware AV-receiver into full-bandwidth surround sound. AC3 Decoder contains multiple settings to correct decoding process such as limitation of resulted signal power, normalization of voice-channel, etc. AC3 Demuxer enables to split each channel from original AC3 file into a separate file. AC3 Encoder provides the encoding process of AC3 file from separate WAV PCM-files without mixing consoles. It is a sophisticated encoder that offers superior audio performance. Further AC3 file may be used for DVD-mastering or as the sound-track for DivX/XViD movie.
