The AES has done some interesting papers on the audibility of lossy encoding here's one: I would also argue that the mix itself (that is, the mastering) has a far greater effect on sound quality than very mild lossy encoding. The mixing engineers I know who prepare film soundtracks here in LA that they can't hear the difference - but their preference is for lossless when possible, just for the theoretical benefits. Unless you've had the ability to compare lossless and 640kbps and 448kbps directly, I don't think you're in a position to know for sure. Essentially they have the bitrate of the DTS-HD core audio)Ĭlick to expand.I'm not convinced they necessarily suck. Those are so good they approach BD audio. I've tried comparisons with some films I have on both LD and DVD, and especially if you know the film pretty well the difference is very apparent.

The difference was in the mastering however, with most DVD tracks being remixed from home systems and poor TV speakers. Most 5.1 tracks on DVD are outdone by their LaserDisc counterparts, which for Dolby had tracks only of 384 kbp/s. That said, higher bitrate doesn't always necessitate better audio. DVD data rate, 5.1-channel audio, 384 or 448 kbps. (It's better to have the file than nothing.) Base 64 twice encoded gd. Personally I can't tell the difference and these files are much smaller to upload for you guys. All of these are sourced from higher quality rips. AC3 / DTS MPEG2 VIDEO / 720480 (16:9) / NTSC / 29.97 fps / 6000 kbps 1: AC3 / 192 kbps / 48.0 khz / 2 ch 2 AC3 / 448 kbps / 48. AAC, also called as Advanced Audio Coding, is a lossy audio format defined by the MPEG-4 standard. My Entire 13.3 GB 5.1/Quad music library (448 Kbps Ac3) UPLOADED. Besides, it is used for films at 640 kbps. There can be a slight jump in quality, but it isn't as apparent on every title. Learn about AC3 file format and APIs that can create and open AC3 files. AC3 is widely used in the laser disc and DVD limited between 384 kbps and 448 kbps. However, it's very unlikely that you'll get the same mix by folding 5.1 down to 2.0 vs playing the 2.0 mix itself. The quality answer seems obvious, and AFAICT is the right one (all other things being equal).
You're not getting a huge jump, but the audio is still superior to the DVD version. 5.1 448Kbps vs 2.0 448 Kbps (AC3) - which sounds better on a 2.0 syste.

DTS was cut in half and limited to 765kbp/s or so (some discs had full DTS like LD titles at around 1530 kbp/s) The 640 kbp/s bitrate is what is commonly found on BD titles that maintain lossy Dolby Digital 5.1 audio from DVDs, such as The Wild Bunch. 448 kbp/s was set as the DVD standard for Dolby 5.1 tracks.
