This means that AC3 can produce a unique, detailed and varied sound effect for humans.<br \/>\nMost HDTV programming today uses AC3 as the standard audio format. The combination with the television broadcast&#8217;s HD signal makes everything realistic, especially the sound.<br \/>\nPreviously, it was not adopted as the standard format for the AC3 company, but Dolby Pro Logic 4.0. Dolby Pro Logic 4.0 can be found on many VHS tapes released in the 1980s.<br \/>\nThe bit rate of AC3 audio on DVD reaches up to 640 Kbps and the sampling rate up to 48 kHz.<br \/>\nBenefits: AC3 is accepted as an industry standard for DVD and DTV media. Almost all the audio tracks for the DVD movies take place in AAC format. AC3 is very compressed and is a small file, but the sound effect is true to the sound of the original DVD. AC3 can be converted to video files such as AVI and MPEG to obtain 5.1 Dolby Digital Surround audio or for playback in media players.<\/p>\n<p>Cons: AC3 is widely used on DVDs and very rarely has it appeared in other aspects. Although AC3 supports 7.1 channels when it comes to audio CDs, it only supports a maximum of 5.1 channels and a limit of 448 kbps.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"AC3_VS_AAC\"><\/span>AC3 VS. AAC<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>AAC or Advanced Audio Coding is very different from AC3. AAC is a type of lossless digital audio format that is promoted as a successor of MP3 because it generally achieves better audio quality within the same file size. The AAC format is a more advanced lossless format than the AC3 format. It will create better sound quality than AC3 with the same bitrate, especially at low bitrate. Below you will find a more in-depth comparison between AC3 and AAC.<\/p>\n<p>History:<\/p>\n<p>AC3 was developed by Dolby Laboratories and was originally called Dolby Digital Stereo until 1994. This format has been taken as an international standard by the Moving Picture Experts Group since 1997.<br \/>\nAAC was developed in collaboration with AT&amp;T Bell Laboratories, Dolby Laboratories, Sony Cooperation, Nokia and Fraunhofer IIS.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The AC3 format, derived from Audio Coding 3, is an extension to surround sound files.
