![]() ![]() But there's always some hit on audio quality. So whenever you resample (even for a tiny bit), you either get ringing, aliasing or loss of frequency range. Based on that experience I know that every resampling algorithm is a trade off in frequency response, aliasing and ringing (same problem as with video resampling filters). But as you probably know, I've implemented resampling in eac3to and I've tweaked the SSRC algorithm to produce better results than the original implementation of the algorithm. I don't have good enough equipment to really test this right now. With your keen ear I'd be interested in your thoughts. It is quite practical to use this now and I think Yesgrey believes it is effectively lossless (yes I know that is oxymoron). Madshi, have you listened to audio sampled by Reclock using its recently improved resampler (speed and quality) in "excellent" mode. My guess would be that studios are also sometimes using resampling and sometimes pitch correction to change audio FPS from 24.000 to 23.976. That applies to PAL tracks, but probably also to 23.976 Blu-Rays. What does this mean? It means that blindly using resampling to change FPS is the wrong thing to do. There are even 23.976 Blu-Rays which have audio tracks with the Mickey Mouse effect still in there!! Also I've seen DVDs where the German PAL track was created by resampling (-> too high pitch) while the English PAL track on the same DVD was created by using a pitch correction algorithm (-> same pitch as original). So you can never know for sure whether an audio track has wrong pitch or not. See advanced settings in config app the VBS notification script now receive the file name or the DVD mode if playing a DVD added a new audio renderer based on 'kernel streaming'. in Spain studios usually use a pitch correction algorithm (like TimeFactory) to create PAL audio tracks! Both methods are used in reality. now allow ReClock to load only with some players/applications. Other Players give you the ability to choose ReClock as sound device enabling you to use the very reliable built in. It sounds pretty much exactly like Foobar2000 kernel streaming. #RECLOCK ENABLE BITPERFECT AUDIO WINDOWS#In configuration->Movies and configuration->DVD it is available. Using ReClock on Windows seems to do the trick. #RECLOCK ENABLE BITPERFECT AUDIO FULL#Its compatible with DTS, DOLBY Digital and DoP signals and offers full HD support up to 192KHz. Even if ReClock is installed it is not shown as available sound device in configuration->Music->SoundDevice. studios in Germany usually use resampling to speedup the original 24.000 masters to 25.000. Its Bit Perfect it doesnt over or upsample the signal. I think that's a very important point to make.Īnyway, your argument is a good one: E.g. It's only 0.1%!! So it's very very much less than PAL speedup. Mind you, just to throw a spanner in the works, do we know they bother to pitch correct the audio 1% down when encoding and if they do the same thing consistently from disc to disc? I would be surprised, as they rarely, but sometimes(!), bother to correct the 4% pitch error on PAL DVDs! ![]()
