![]() In order to experience surround sound, use an AV receiver or TV capable of. – Journey into Photography 101 (.in progress. DTS audio will not be converted and will be passed directly to the HDMI output. But the actual bitrate of “1536 Kbps DTS” is 1509.75 Kbps, and that requires only 2012 bytes. Q: So how does DTS get away with it with 1536kbps streams?Ī: A DTS audio frame has 1/3 the number of samples as AC3 (and 1/3 the duration), which would imply that 1536 take up the same space as a 512 AC3. 512K frames are 2048 bytes, 576K frames are 2304 bytes, and 640K frames are 2560 bytes. Is this true? Is 640kbps considered out of spec, or just considered not proven to work reliably?Ī: Bitrates of 512K and higher present problems to some multiplexers and players because the size of the audio frame exceeds the payload size of one DVD pack (2025 bytes). Q: I keep reading in DVD guides that the bitrate of AC3 audio on DVDs is limited to 448kbps, even though the maximum bitrate for 5.1 AC3 is 640kbps. If it actually is superior my feeling is that it is so by such a slim margin that most people could never actually tell the difference between it and another good codec in a blind test. I can tell you that my personal opinion is that it’s a fine codec but I remain skeptical that it is superior to others. DTS-HD Master Audio is an advanced lossless audio format developed to offer a high-definition home theater experience with the quality of the studio master by. AAC has its supporters, some of whom are Apple fanboys. I personally find AAC cumbersome to deal with as it is not valid for DVD or BluRay audio. ![]() Whether it is better than AC3 or not is certainly debatable but given that it is a lossy format converting from AC3 to AAC is going to entail some loss of quality, even if you can’t perceive it. The fact that AAC supports multiple channels is just a bonus but it really was designed for uses like iTunes rather than as a movie soundtrack.ĪAC is lossy as is AC3. AAC was really designed to replace MP3 rather than to replace AC3. “ If AAC is a superior format comparing to AC3?“
