As part of the ISO standardized MPEG-4 specification, AAC supports multiple sample rates (8000-96000 Hz), bit depth, and multi-channel (up to 48 channels).Ģ. What are the advantages and disadvantages of AC3 and AAC? The following detailed comparison table will explain it clearly and easily.ġ. Part 2: Advantages and disadvantages of AC3 and AAC The main reason is that AAC appeared a few years after AC3, and is recognized as an excellent codec in many respects compared to MP3 (very similar to AC3). When asked which codec produces the best sound, assuming AAC or AC3 is used to encode the audio at similar bit rates, the results may be similar. Of course, this is better than using the irreversible AAC format. It can be encoded in lossless AC3 format.
In general, AC3 appears to be an irreversible format, but not all encoded AC3 files are irreversible. Generally, you cannot encode or decode without the use of specially licensed software or hardware. The AC3 Dolby Digital format is mainly used for videos only.

However, AAC excels with an output of 400 Kbps on 5.1 channels and 180 Kbps on dual channels.īesides Movie / DVD / Blu-Ray projects, I rarely use AC3. AAC can transfer any bit rate from AC3 and compress data better, but it is considerably more complex than AC3. Developed as a successor to MPEG Layer III (MP3). It is also used in 640 kbps movies.ĪAC, also known as advanced audio coding, is an irreversible audio format standardized as part of the MPEG-4 specification. AC3 is often used for 384 kbps and 448 kbps DVD or laser discs.

Originally, AC3 was widely used in 5.1 channels and is similar to Dolby Pro Logic.

In this article, we will explain the difference between AAC and AAC, compare the advantages and disadvantages of each, and how to convert DVD to AC3 / AAC.ĪC3, also known as Dolby Digital (audio code number 3), is an audio format developed by Dolby Laboratories, Inc. When I want to extract audio files from video files or Blu-ray / DVD, I don’t know which one to choose, AC3 or AAC. For example, I’m compressing from the same source, but which is better compared to a 256 kbit AAC file or a 384 kbit AC3 file? ”
AAC is more efficient and sound quality than AC3. But I don't want to re-encode 50% of my movie collection to sub-DVD quality audio.“What is the difference between AC3 and AAC? I want to compress PCM and convert it to AAC / AC3 to save free space, but I don’t know which is better. Avidemux is exactly what I want and it does what it does perfectly. Any other suggestions? I am absolutely gutted. When I open the project, the GUI doesn't even change and Audio shows "Copy", but I went ahead and saved the file.Ĭhannel positions : Front: L C R, Side: L R, LFE

I setup the GUI with the parameters that I normally use and save the project, and this givesĪdm.loadVideo("F:/DOWNLOADS/Completed/STAR WARS SAGA 1977 2005 BluRay 1080p QEBS5 AAC51 PS3 MP4-FASM/Star_Wars_Episode_IV_A_New_Hope_1977_1080p_BluRay_QEBS5_AAC51_MP4-FASM.mp4")Īdm.audioCodec(0, "Aften", "bitrate=384", "mode=0") Īdm.setContainer("MP4V2", "optimize=0", "add_itunes_metadata=0")Īdm.audioCodec(0, "Aften", "bitrate=448", "mode=0") Unfortunatly, the Project workaround doesn't appear to work.
