Hey guys, I have a couple of different reverse L + R problems which I don't think are actually even related to each other. The first is my computer speakers play reversed, there's 1 cable going from the computer to the unit, which has two speakers correctly plugged in L + R. So it has to be connected properly. Weird things happen for example I have an original purchased CD which correctly plays left guitar on my computer and plays correctly left guitar on my home stereo. However I burned a copy of the same CD and it plays incorrectly right speaker on the computer but correctly left on my stereo. Why does the original CD play correctly left on both computer speakers and home stereo, but the burned copy of the same CD only plays correct on the home stereo but reverses on the computer ? When I go into my computer settings I go to "AC97 Audio Configuration" and use the "speaker test" function I click on the right speaker and it plays a sound in the left, however if I plug headphones into the same jack it's correct. Like I said there's only 1 cable connecting the unti to the compter, and the 2 L + R speakers coming out of the unit are 100% correctly set up L + R. And a second seemingly unrelated different L + R reversing problem I have. Every now and then when I rip a CD to my HD using dbpoweramp it will rip in reverse order, for example I just ripped a track off a CD 6 times, the last was reversed, I tried another CD and ripped a track about 8 times, 2 times it was reversed. Would this be a problem with dbpoweramp or my LG : HL-DT-ST DVD-RAM GSA-H55N 1.05 drive or something else ? Thanks in advance for any help.
I didn't know you could specify an order of the ripping of the tracks. If you didn't it is not a bug or an error. If you are interested in the minutia of how it works this is not the place to post that question. You will have to post on their forum. The L&R is a bug but I can't help you there. Sorry
Sorry I don't understand what you're refering to when talking about order of ripping tracks... So I tried ripping another single track on a CD with dbpoweramp, I ripped the track 6 times and the 6th time L + R was reversed. I asked about it at the dbpoweramp forum and they say it can't be the programme so obviously blame points to my CD burner : ------------------ If they are swapped then it is a fault of the CD drive as it is impossible for any ripping program to request the data in a reversed state (data is delivered in whole sectors of 2352 bytes / 4 = 588 samples of L + R) ------------------
I don't know that you can 'blame' the sequence on the drive. To you, you are thinking that the sequence is important but I am sure it does not 'care'. Maybe it is how the drive reads the disk or even where the head is when you put in the disk. The ripping program can request any sector it wants. I bet it just requests all the sectors because it doesn't care and neither should you.
Well I care because I collect a lot of live material from the same band, certain members are always mixed guitar left, other guitarist right etc, so it's obvious and can be annoying when channels are incorrectly reversed.
Oh bye the way the first of the two problems is solved. It's not my computer but it is my external speaker unit, it's all connected L+R speaker properly but plays in reverse, I have the same unit at another computer which works correctly when I plug it into the computer I was havving the problems with, so it's not my computer at all... The second problem of some CD's ripping in reverse stereo (using dbpoweramp), seems to only be happening with old scratched up CD's.
I have just realised that the channels reversing not only happens when sometimes ripping a CD, but it also sometimes happens when playing the music straight off the CD. In fact listening straight off the CD right now I'm certain it's reversing channels actually while it is playing, it's reversing at the exact same spot every time. I'm 100% certain. Does this also mean it could reverse L+R half way through burning ? - I don't think so ?
VERY interesting! I never stated that the L&R reversal was a trivial event. It is for me but it is a real bug. Only the sequencing is not a real problem or a bug. You might find the top sticky very illuminating. Your experience is proof positive about some of the 'mumbo jumbo' about CDas and optical reads. What you have done is improved the accuracy of your optical read so that the audio does not have to be 'fudged' as much. It is believed that even new unblemished CDs have a good bit of fudging going on when they are played. CDs are made to be hard to read to baffle rippers. They rely on the error corrections to fudge music well enough the human ear can not hear the difference, at least on a new disk. You are able to hear the L/R switch now that you are listening for it but most of the rest of the fudging is beyond your ability to resolve the differences. Most fools think they could actually hear the fudging IF there was any. As you can see, even big changes (fudges) are not apparent with out trained listening to the exact part that is altered. You probably never noticed the L/R switch till now.
