Question - Youtube sound

post #1 of 16
Thread Starter 

Greetings.

 

Hope this is the correct forum section.

 

Ok so im not to well versed in the ways of youtube, so i have what likely to be a silly question.

 

Why is it, when i play music such as this

http://www.youtube.com/watch?v=Q02mQqXpHEo&list=RDQ02mQqXpHEo

on youtube it comes out of all my speakers in 5.1, good bass and all.

But when i download that same music using a FireFox pluggin like CYS and then play it on Winamp, VLC, or WMP it only comes out of my 2 of my speakers and the bass and loudness is complelty gone.

 

I cant seem to find any way of downloading the audio in such a way that it retains 5.1, or what ever fake 5.1 its using.

 

Disclaimer: I know youtube sound quality is lossy, i would much ratehr get ahold of FLAC files but the music in question is not 'proeffionaly' made so no lossless files exist as far as im aware. Some have diretc downloads of the MP3's , but again those MP3's dont sound anything like the youtube sound.

 

This wouldnt be a problem if i had internet were im going on holiday tomorrow. But since i wont have internet access, i wont be able to listen to the music online. I need a download >.<

Its transcoded to mp3 when you downloaded it. MP3 does not support 5.1.

Just got back from holiday. Late response.

 

Yea I figured as much. However I tried downloading as AAC, and other formats, didn't help.

 

That's why I assumed youtube must have some funky settings going on.

 

If you or any1 else has any advice on how to get youtube music downloads playing as they sound from youtube, please let me know.

 

I know youtube doesn't have the best quality but, as I explained, a lot of the music im listening to on youtube, in fact all the music that I listen to on youtube, are made by the users and don't have lossless file formats available.

Youtube uses AAC, so the only reason AAC wont give you 5.1 if youtube does is that the plugin in question is re-encoding as stereo.

 

As far as I've seen, if I was inclined to use such a plugin (for educational reasons) the best one to be used is the following:

https://addons.mozilla.org/en-US/firefox/addon/youtube-video-and-audio-dow/?src=search

 

It claims to extract the original audio and in a test with another plugin that downloaded the audio as a wav file, they looked completely identical in audacity. I used the 256 kb/s AAC/M4A option, though it is strange considering youtube only encodes 196 kb/s.

I always thought that YouTube degraded the sound quality of whatever you upload, and as far as I know, YouTube can only stream audio in stereo.

 

I use this Firefox add-on to download YouTube videos as MP4/FLV, and the files sometimes have slightly better image/audio quality than streaming.

 

I also downloaded three versions of the song (from YouTube, the link in the description, and SoundCloud) with bit rates of 191, 256, and 320 kbps. They all sound about the same. Just put the song info into a search engine to find download links in seconds.

When a video with 5.1 DD+ (Dolby Digital Plus) audio is uploaded to youtube, that audio is intact and embedded with the video. That audio can be extracted using an AV receiver that is licensed and supports 5.1 DD+. If your PC soundcard is licensed and supports DD+ then you can have 5.1. Notice that I always say license, that is because DD+ is a licensed feature.

Oh, that's cool. Perhaps @SolarNova has the qualifying equipment then...but I wouldn't expect that type of remix to be in surround sound.

Surround sound is NOT DD+, google it.

Oh, I thought multi-channel implied surround sound if it was more than two...

 

It appears that Dolby Digital Plus is actually "a digital audio compression scheme [...] for transport and storage of multi-channel digital audio." So it's essentially a file format for surround sound, right?

In a nutshell, surround sound became a generic name for anything that has more than two channels, analog or otherwise, the name precedes 5.1 digital audio. Yes, that is DD+. DD+ also covers 7.1. But these can only be done using HDMI. DTS 5.1 is supported by SPDIF I believe.

Ah, then my statement about qualifying equipment (which you described) still applies.

Any licensed equipment. Let me give you an example. The company I work for has a product with an HDMI input. The HDMI licensing stipulates that the HDMI input must have an HDMI label, it should say HDMI. Ours didn't so we broke the agreement. Dolby is the same. Any product that is Dolby licensed must have a visible Dolby label somewhere. If you don't the FBI will knock on your door.

*checks HDMI cable in paranoia...wipes brow in relief*

 

I remember playing a 1994 Super Nintendo game with the fancy Dolby logo animation at the beginning. It was amusing because the audio was pretty lo-fi.

Not your door but the company who makes your equipment. ;)

Yeah, I know. lol. Just trying to inject a little humor wherever I go.

 

Now I'm reminded of those mattress tags with the warning not to remove it, and how as a little kid, I thought they were going to come and take me away.

 

...It's too easy to get off-topic on all these threads. With as many posts as you have, I'm sure you know that even better than I.

 

At any rate, I would be surprised if that amateur remix has more than two channels in the original file.
