AC3 to PMC: Convert AC3(Dolby Digital AC-3 Audio) video to PMC with River Past Crazi Video
What is
AC3?
Dolby Digital, formerly
known as AC-3, is a digital audio compression format. Dolby Digital takes advantage
of how the human ear processes sound. When coding noise is close to the frequency
of an audio signal, that audio signal masks the noise so that the human ear
hears only the intended audio signal.
Dolby Digital is used with digital
versatile discs (DVDs), in North America only. European DVD's use MPEG audio
instead.
Dolby Digital provides five full-bandwidth channels, front left, front right,
center, surround left, and surround right, for true surround sound quality.
A low frequency effect (LFE) channel is included that provides the sound needed
for special effects and action sequences in movies. The LFE channel is one-tenth
of the bandwidth of the other channels and is sometimes erroneously called the
subwoofer channel. This multichannel scheme is known as 5.1 channel.
To convert AC-3 audio to other formats in River Past software, please have
AC-3 Decoder filter
installed.

Note: To convert from AC-3 files, you must have open source AC-3 decoder installed.
Once the AC-3 Decoder Filter is installed, you will also find a AC-3 Control Panel in your (Windows) Start | Settings | Control Panel area. It allows you to change the settings for the decoder.
