Is the official suffix for ogg vorbis (audio) files .ogg or .oga?

Did something change? Every Ogg Vorbis file I've seen is .ogg.

Same here, the only divergence I've heard from .ogg, is .ogv, for ogg theora.

Read Wikipedia (http://en.wikipedia.org/wiki/Ogg)on the difference between .ogg and .oga.


The term Ogg is commonly used to refer to audio file format Ogg Vorbis, that is, Vorbis-encoded audio in the Ogg container. Previously, the .ogg file extension was used for any content distributed within Ogg, but as of 2007, the Xiph.Org Foundation requests that .ogg be used only for Vorbis due to backward compatibility concerns. The Xiph.Org Foundation decided to create a new set of file extensions and media types to describe different types of content such as .oga for audio only files, .ogv for video with or without sound (including Theora), and .ogx for applications.[3]

ogx for applications? What kind of applications would you be putting in a media container format!?!

Gedit.ogx: Open it with VLC, hit play, edit text files with it! Great plan, guys!

Seriously though, maybe it's some kind of no-installation-required software package format?

Read Wikipedia (http://en.wikipedia.org/wiki/Ogg)on the difference between .ogg and .oga.

Or read the xiph.org guidelines that Sefs wikipedia quote is referencing-

http://wiki.xiph.org/index.php/MIME_Types_and_File_Extensions


.oga - audio/ogg



Ogg Audio Profile (audio in Ogg container)
Applications supporting .oga, .ogv SHOULD support decoding from muxed Ogg streams
Covers Ogg FLAC (http://wiki.xiph.org/FLAC), Ghost (http://wiki.xiph.org/Ghost), and OggPCM (http://wiki.xiph.org/OggPCM)
Although they share the same MIME type, Vorbis and Speex use different file extensions.
SHOULD contain a Skeleton logical bitstream.
Vorbis and Speex may use .oga, but it is not the prefered method of distributing these files because of backwards-compatibility issues.

.ogg - audio/ogg



Ogg Vorbis I Profile
.ogg applies now for Vorbis I files only
.ogg has more recently also been used for Ogg FLAC and for Theora, too these uses are deprecated now in favor of .oga and .ogv respectively
has been defined in RFC 3534 (http://tools.ietf.org/html/rfc3534) http://www.ietf.org/rfc/rfc3534.txt for application/ogg, so rfc 3534 will be re-defined

RATIONALE: .ogg has traditionally been used for Vorbis I files, in particular in HW players, hence it is kept for backwards-compatibility



.ogg is the offical .xiph naming for ogg vorbis.

Mozilla still has downloadable videos with a ".ogg" extension; so Gnome puts a music note icon on them.

Rhythmbox went through a period of ripping my CDs to .oga but I think they are back to .ogg again now.

Perhaps we should file a bug against Ubuntu to bring consistency to the subject. If upstream specifically requests that we use the .ogX extensions then we should review the relevant applications in the repo and ensure that they support these both for import and for playback as well as making it the default.

*edit*

And here we go:

The major problem was that ogg could have video only or audio only or a mix.
So very confusing for users and applications that didn't read the header.
oga and ogv are far better descriptions because you can know just by looking at the extension whats in it.

Meh, I think extensions are the old way of denoting file types. Any modern OS should be able to determine the file type, and show you the extension. With that being said though, I still like extensions, it makes using the terminal much easier.

He, he. You make it sound like Linux is sentient.
