fas42 Posted November 2, 2020 Share Posted November 2, 2020 People can't wrap their heads around the fact that if a YT clip of a high end system playing doesn't sound good, then it's not the fault of YT. Being there in person listening the system that was recorded, the faults that are so obvious in the video are still there; but are usually "swept under the rug" because other aspects of the sound of the playback, live, are more 'impressive' - human hearing doing its usual compensating thing. On a video clip, there is nowhere for the problems to hide, 😉. sandyk and kumakuma 2 Link to comment

Confused Posted November 3, 2020 Share Posted November 3, 2020 Isn't this one of those "the truth lies in the middle" issues? For me, I think I can tell something from You Tube videos. Indeed, I have been lucky enough to visit shows, then later find You Tube videos of the kit I actually listened to at the show. Do you get some sense of the performance of the system? A little I think, yes. On the other hand, this has to be limited in scope. Consider, you might hear something at a show and be impressed by maybe the level of microdetails, or how realistic voices sound, or the dynamics, or the impressive impact of the bass, and so on. Personally I cannot fathom how you can truly know how these aspects sound in "real life" from a You Tube video, unless the microphone, the recording system and your own system at home for the listening were all superior to the system in question. Take one example - visceral bass impact. If whatever you listen to the You Tube clip on is not capable of visceral bass impact, how can you tell from the clip exactly what this was like for real. So yes, I think you can pick up something for these You Tube clips, but not everything, the whole process in necessarily limited. Furthermore, you can never be 100% sure what you are actually listening too.... I posted this a while ago, this is a Cyrus demo at the Bristol HiFi show in the UK. Running through about 2min 30s into the video, the music plays without interruption, but the seated visitors at the show mysteriously change into different people..... So clearly the sound and the video were not made at the same time. (unless visitors were being beamed in and out of their seats using Star Trek technology, although this technology has not made it to Bristol yet, as far as I am aware) Windows 11 PC, Roon, HQPlayer, Focus Fidelity convolutions, iFi Zen Stream, Paul Hynes SR4, Mutec REF10, Mutec MC3+USB, Devialet 1000Pro, KEF Blade.

STC Posted November 5, 2020 Share Posted November 5, 2020 I may have missed earlier posts here and therefore just confining to the last two posts where reference made to me. For YouTube video or even high resolution audio samples ( which is usually the case before it is compressed by YT), it will only be useful for system evaluation as heard in situ if it is recorded with binaural mics and played back using headphones. Binaural recordings capture the sound field. That is the actual sound waves arriving at your ears. You are not only judging the speakers but also the room acoustics. you are judging the phantom image that is created by the stereo playback which depends on how you place them. Will these audio samples be the mirror image of actual sound? No! Unless you think your hi Rez audiophile recordings are the exact sound of the actual event. There will be differences and compromise. The mic quality, pinna difference and the playback method will affect the SQ but you should still able to distinguish the better ones. This is only true if you capture the sound field using binaural mics. YouTube recordings of system playback using videomic or smartphone mics are misleading. This is so true with today’s modern smartphones that come with noise and echo cancellation where the algorithm’s main job is to make the audio better. The point of making these video is to convey the actual sound as heard by the listener at the sweet spot. The only way to do this is to capture the sound field using binaural mics. Here is a video using binaural mics comparing 1) Dynaudio Saphire 2) Vandersteen 2CE 3) Magnepan 1.7i 4) JTR Noesis 210RT, speakers. and this is the sound of Sound Lab speakers ( hi Rez). For Apple to Apple comparison you can compressed it as much you like to match the YouTube SQ. https://1drv.ms/u/s!Avexw_l7DM5sgsAbtxb6ZjW4JhuwRA ST ST My Ambiophonics System with Virtual Concert Hall Ambience Link to comment

All performance comparisons in this area on YouTube are a waste of time due to YouTube's <128kB/s .aac audio and require a vivid imagination to obtain any meaningful information from them, especially in the HF area and impact of drums etc. which also need wide bandwidth to capture the fast rise and fall times. Add to that typical affordable Binaural microphones which are unable to do high quality system performance justice. However, if you are able to listen to the normally inaccessible YouTube 529kB/s .aac stream, ( PID 0x0002) you may get a rough idea ONLY.
