Hi,

I've always been anti-streaming in the past, preferring the high sound and video quality of physical media like Bluray. Recently however I discovered the very high quality of modern streaming such as Medici and I'm interested again. I'm curious

- What kind of codec is used by crunchyroll streams?
- is surround supported?

I realize I'm in a minority here, but that sort of thing to me is worth being a premium member over.

Thanks.

Interesting how similar questions seem to come in waves. This recent post by TAO pretty much addresses surround sound:

I'll quote it here, since you aren't currently a member, you may not be able to read the group it is in...


One issue is that most anime produced in Japan is mixed with only stereo sound. Surround sound mixes are more likely to be found on anime movies, but rarely on series.

The odds of finding a 5.1 mix improve considerably when you are dealing with a dub created in the US.


For anyone that doesn't want to take my word for it, and doesn't have a DVD collection to check to verify what I've said, scroll down to final question (from Jitendar) and the answer:

This is from the FAQ ( http://www.crunchyroll.com/help). I'm not sure how up-to-date it is, but it's probably close:

Our videos are encoded using H.264 [...]

Ah.

My bet is AAC (or some fork of), but hopefully one of the Tech support people will swing by and post a note.

I use DTS on my setup it works for me, so yes it does support it.

iirc, the audio chanels are muxed down to Stereo from the original source content.

The amount of bandwidth required to deliver 5.1 content over the web would be unsustainable and viewer prohibitive.

What about when the show is out of simulcast & is in the library ? The music on Gosick sounded great on my 5.1 . The latest episode (today's) of Chaika the Coffin Princess was disappointing , especially in the big battle scene ... If Netflix can do it ... . The Toradora Blu-ray I bought is Dolby Digital , the stream isn't .

The bandwidth required for audio pales in comparison to video. Different formats, some of which limit what the surround channels are capable of, take even less.

CR could definitely do it, but if 95% of their material is only stereo to begin with, there isn't much incentive (especially when you consider the percentage of people that are likely listening on a full home theater setup vs. on a tablet, phone, built-in TV speakers, etc.).

It's a shame . They could at least transmit the audio in Dolby Pro Logic stereo . That way any decent sound system can up convert it . Missing out on half the experience.

Nearly, if not all, TV series are only produced/broadcast in stereo sound anyway.

Well at least the blu-rays have it ... wonder why Gosick sounded so good ? Fairy Tail does too ... Wouldn't mind getting a copy of Gosick if it was on blu-ray (and dubbed would be a plus too) .

you are correct, but user experience still has to be considered.

It all depends on the audio engineer that's mastering and mixing the series audio. There are some series that were clearly mixed in Dolby Prologic II and sound amazing. They can trick you into thinking that discrete 5.1 is being fed into your receiver (Another, JoJo's Bizarre Adventures), and other series that will sound underwhelming (Overlord, Love Chuunibyo & other delusions).

At least you can rest assured that you're hearing the audio as it was originally mastered.
