A Quick Way to Convert AC3 to MP3 for Smooth Audio Playback (PC Solution)

AC3 or Dolby AC-3 is an audio format developed by Dolby Laboratories for surround sound effects in DVDs and Blu-rays.

Usually, AC3 audio comes as the soundtrack of movie files like MKV. In other cases, there are music files distributed in AC3 format. However, due to its multi-channel feature, it requires more resources and technology to play, so not every device supports it. For example, you may encounter the "no sound in video" problem.
