Can a stereo, or mono, ogg encoded file be looped without the delay/pop you get when doing so to an MP3 file?

Ogg Vorbis provides gapless sample-correct playback.

>>Can a stereo, or mono, ogg encoded file be looped without the >>delay/pop >>you >>get when doing so to an MP3 file?Though I've never tried myself, I'm sure Ogg's could be looped without gaps. Ogg supports no-gap encoding of back to back tracks (for live albums). Given this looping isn't much different than playing the same song back to back. What I am not sure of is how well Ogg would handle looping of a section within an Ogg file (since I think I remember reading seamless playback was accomplished by fixing up the ends of the encoded file?). At any rate the complete Ogg file should loop no problem. PS - It's not that hard to loop an MP3 file as long as you know what delay the encoder inserts (which could be hard unless you encode them yourself), and the loop point is at a zero crossing. If you are encoding yourself it's really not that hard to solve all looping issues if you embed enough of the right data in your quasi-MP3 file. Bored?

Yes. Is "feature" of MP3. Ogg doesn't have this 'feature'

Yes, as indicated, both MP3 and Vorbis files can be looped this way, assuming you're talking about looping a full file. It's more in the way the streaming code is written rather than a feature of Vorbis (although the Vorbis codec and decoding API are superior to anything else out there, IMO). You have to make sure you do not stop and restart the buffer or channel you are decoding to - just reset the decoder to the beginning and continue filling the buffer / channel. I've recently written an audio engine where this is done. <p>> -----Original Message-----> From: owner-vorbis@xiph.org [mailto:owner-vorbis@xiph.org]On Behalf Of > Szick, Frank > Sent: Monday, October 14, 2002 2:00 PM > To: 'vorbis@xiph.org' > Subject: [vorbis] Question for Game Audio Developers? > > > Can a stereo, or mono, ogg encoded file be looped without the > delay/pop you > get when doing so to an MP3 file? > > Thanks-Frank > --- >8 ---- > List archives: http://www.xiph.org/archives/ > Ogg project homepage: http://www.xiph.org/ogg/ > To unsubscribe from this list, send a message to 'vorbis-request@xiph.org' > containing only the word 'unsubscribe' in the body.
