Hi all,

Like a few others here, I'm about to embark on a re-ripping project to bring my collection up to snuff (not to mention, up to date, since half my stuff isn't ripped to begin with). A lot of my stuff was ripped before I settled on LAME with 192 (or 256) VBR. Before I start, I was thinking about ripping to Ogg. Sadly, I don't have the space available to store everything in FLAC to reconvert at will, so I don't want to re-rip only to re-rip yet again, later on.

So, my question... what's the state of Ogg on the Empeg? I've done a bit of browsing through other threads, but just to confirm, Ogg requires v3alpha8, which may, or may not have issues. Are the issues reasonable to put up with, just for the Ogg support? You may assume that, on uploading new tunes, all I want to do is use jEmplode, and no futzing beyond that (a one-time initialization type futzing is okay, though). Does the alpha seriously break anything from 2.0final?

Also (and I may be entirely out in left field on this one), is the MP3 decoding done via software or hardware, and, if the latter, does using Ogg, rather than MP3, cause any significant impact on CPU/RAM usage?

And, finally, a poll to satisfy curiosity...
I'm using Ogg on the Empeg

Well, Ogg Vorbis is lossy, as you know, so if something even better comes out, you'll still need to make this decision. My advice to you: rip to FLAC and then archive to DVD-R.

Yes, it does. The Ogg (and FLAC) codecs fell out of the audio path rework that got done for Karma, so you'll need v3a8.

Depends. I've been using v3 alphas exclusively for over a year and, while I do get some issues with v3a8, I've been generally happy. It does occasionally reboot on me, but I can live with that. I don't, however, use the radio that much, so I can't comment on the level of functionality there.

IMO, not seriously, no. And gapless playback is worth the cost, as far as I'm concerned.

All of the empeg's codecs are software. The Ogg Vorbis codec is heavier on CPU/RAM usage than the MP3 one, because we got a StrongARM-optimised MP3 decoder from ARM, and the Ogg Vorbis (and FLAC) decoders used in v3a8 haven't had as much optimisation work carried out on them.

Wow. 9 minutes. I'm glad I put that poll in, so that everyone else that reads this thread will have something to do.

Yeah, that would mean purchasing a DVD burner, though, and I've already blown my current toy budget on hockey gear. At the moment, I'm reasonably happy with the lossy compression -- my re-ripping *everything* is just because, since I have to rip a ton of stuff now, anyway, I figure I might as well redo everything else just to just get it all in the same format. I found that my time spent in the ripping/encoding is minimal compared to the tag editing, so once I get the tags done, I plan to keep a mini-cddb.

Ah, cool. Occasional reboots, I can deal with. I'm not a frequent radio user, either (mostly it's just a click over to radio to show passengers that it's there, and tell them that I put the tuner together from a kit ). I'll see what info I can dig up about alpha/radio issues.

"Shuffle mode on, down, down, down" -- pretty much negates the need for any sort of gapless playback.

I really need to setup per-album playlists.

I'm afriad to put Alpha8 on my main player, but it's on my backup and I can't begin to explain how cool the crossfade is for the "down , down, down" type of playing!

Yep, gotta second that. Crossfade looks silly, until one uses it for the BIG SHUFFLE..

Typical Canadian! You find 'em on the street corner with a stack of pucks in a brown paper bag, then they stagger home at 3AM and tumble over the foot of the bed clutching their hockey stick! Why do their wives put up with it?

No, when you look at it as just $80, it's not that much at all. The problem in my case is that "just $80" here, and "just $80" there has a tendency to add up very quickly, because I say that *too* often. :-D Also, about half my salary is currently being shunted into my 401k, because I forgot to reset the contribution level back to a sane amount after increasing it at the end of last year to max out my contributions, which isn't leaving me much play money at the moment.

I'm kind of at the point where I want to get rid of all my computer junk (I'm limping along here with a Pentium MMX, and a DEC Alpha), so I'm not particularly keen on buying more hardware until I can replace the whole kit-n-kaboodle. And then see above.

On some of us!

I am one of the people that voted "yes" above. Not sure if I can answer your questions directly during lunch, but I am in a similar place as you -- cap to FLAC, keep running v3Alpha8?

With a low (or maybe zilch!) likelihood of another Amerfoort surprise, I have considered reverting to 2.0, but, yeah, I love that crossfade! I would probably revert at some point though. For one thing, I ripped/encoded a whole bunch of new stuff into Ogg, but screwed it up I think -- too high quality? -- and they are oversaturated and I get noticable distorting of highs in playback.

So, if I am going to redo those, I am thinking FLAC and more disk space to cover the optimist/pessimist bases.

I'm using v3alpha7 on two different empegs, one in the office, one in the car. I've only ever ripped my own discs to Ogg Vorbis files, that's over 12000 songs on the unit in the car. Mostly it's been working fine ever since the v3alphas were released, there have been some minor problems, but only one problem that's ever affected playback, and that was with an earlier release, v3a5 maybe?

All of the other issues are much easier to live with. There's the songs getting marked problem that's been mentioned before. There's the song name being changed to "various" on occasion, this has also been mentioned before. And every now and then I have a problem uploading songs, and the connection dies. It's on occasion been a bit of a pain to cleanly recover, needing to get in via telnet or the serial port to run fsck. And there's been a few issues with emplode.

Hydrogenaudio.org and rarewares.org are the best resources for ogg stuff, including hints about reccomended versions and pentium 4 compiles.

Those don't sound too bad.

Yuck. I don't like the sound of this. I can do it, but I'm lazy. I'm now in the Apple stage of my computing -- I just want it to work (says the guy that runs custom kernels on obsolete hardware).

Those don't bother me, since I only use jEmplode.

Hmm... pentium 4? I wonder if they have any hits for pentium MMX (409 bogoMips, baby!), or a 64-bit DEC Alpha?

I guess my last question now (not necessarily directed at you, but the thread readers in general), is, what are the ramifications of upgrading, and then deciding to down-grade back to v2.0final? My search-fu suggests it's just as simple as just flashing the previous image again. If that's correct, then I guess I'll toss on 3a8, and play with it a while before I decide about Ogg.

One issue I see often with v3a8 is if I select a specific song, many times the player will lock up with only a couple seconds left in the track. Usually I can reboot, it starts playback from an earlier point, then I down, down, down to get past it. The same track will play fine later, I'm positive it's not my mp3's, but occasionally it will lock up. But I love v3! I can live with that minor annoyance.

Yeah, I had that happen once, but I just slammed the Empeg down on the table real hard and it started right up again.

WELL, the P4 compiles are noticebly faster than the generic x86 compiles. Just the way it is.

Actually I mispoke, all of the upload and lost connection problems are with jEmplode. I've posted about some of these problems before, but nobody else seems to have the same issues.

I was using Emplode 2.1 for a very long time with no problems, and then something bad happened, and then a laptop got stolen, and then some other stuff happened, so I just haven't tried it recently.

<offtopic>A ganglion cyst. I've got one on my left hand, and I can have an orthopedic surgeon remove it for a total out of pocket of around $1500 after my insurance deductible and all that. Or, I've also been told about the big heavy book trick. I honestly can't decided which option's worse: the pain of the book or the pain of the $1500 dollars. At this point, $1500 seems more painful, though.</offtopic>

I'm back on topic now...

I switched back and forth between v2 and v3 for a little while, and ran into a bit of a problem. I was getting goofy problems with autochange visuals, and I finally traced it to a problem of switching between versions. What would happen is that I'd turn autochange on a time interval on v3, then when I reverted to v2, the visuals would change sometimes every couple of seconds. No change to the visual settings would fix this. The fix was either to nuke the flash with player -i, or go back to v3 to turn off autochange.

I haven't tried alpha 8 yet, so maybe it's not a problem anymore. Even if it was, you'd just have to stay away from autochange to avoid it.

I never tried to get rid of a ganglion cyst via the book trick. I also never saw a doctor. They would eventually break and dissipate on their own, then re-develop months later.

The book trick always sounded dangerous to me. Loss of the use of one of my guitar-playing hands, even if temporarily, due to a painful blunt injury, would be a problem.

Lately, I haven't had one. It might be because I've been on prescription anti-allergy pills for a nasal thing unrelated to the cysts.
