Mono Ogg Encoding ?

[iron31]

is it possible to encode mono wav in mono ogg ?

thanks

normally yes, but I guess it won't work in besweet, doesn't support this atm, just dl dailyvorbis from rarewarez, and encode it.

BTW, for coding wav to vorbis, don't need besweet anyway, just an encoder.

P.S. As people from Xiph are very strict about their names, I want to tell you that ogg is only a container, vorbis is the name of the audio-codec.

Since vorbis uses kind of joint stereo( if I understood right the previous posts ), you don't loose a lot of space encoding your wav with oggmachine + besweet. Moreover, using mono might lead to sync problem, with video running twice as fast as the audio ( the issue exist with MP3 VBR mono... )

Sure, you're (almost;) ) right, I remember now..
Last time I encoded something in mono, audio was double-speed on playback.

Raist that's why we have a mono2stereo dsp plugin for BeSweet ;).

Well, I hope this is only a workaround, and there will be a new release by tobias supporting mono-audio in ogm.

Sounds somehow crazy to me, to encode a mono-file as stereo-file?
Don't misunderstand me, DSPGuru, I honestly respect your work (no, I LOVE IT) but still a little bit stange.

Have you tested? If I'm correct, resulting ogg-file shouldn't be bigger than mono-one, since there is no difference between the two channels in a dual-mono-file.

there will be a support for mono tracks, but i think that this little hack is also nice, simply because the two channels are identical, and coupling should take advantage of this property.

i recently encoded a mono ac3 with besweet using th ogg machine. since i didn't know of the above mentioned plugin, i just chose 'stereo' in channels mode. so what's the difference?

[DSPguru]

if the ogg file came out correctly, so it's great :). but there are other output formats that must have this plugin in order to properly encode mono inputs.

[raistlin2k]

Well, perhaps the ogg is ok, but what about the ogm-container?
Should be speed-troubles as mentioned above, no?

no speed troubles. the resulting file is a stereo file (winamp shows that)

Done mono AC3 to mono OGG with headAC3e before, worked fine. Also done mono WAV to mono OGG with OGGdrop before.

thanks 4 all.
