If you have a soundcard that offers other bit-rates and sample frequencies, SoundForge will happily record and save at higher (or, indeed, lower) resolutions. It's questionable whether a higher sample frequency is worth it. 24 bits certainly are, if recording music with any dynamic range. Maybe not from vinyl though? What's the practical dynamic range off vinyl? About 13 bits, from unplayed perfectly clean top-class vinyl. Of course, for capturing 13bits of information into a computer, 16bit recording is de rigeur. No, it's simply convenient. You can certainly use 13-bit to reduce storage requirements. Also, I would argue that beyond the technical 13bit dynamic range limitation that you state, there's a whole bunch of euphonic stuff going on in bits 14, and below. You can argue that if you like, it will still be irrelevant........ You should be aware that in a properly dithered 13-bit A/D conversion, information well below the noise floor will be captured, just as it is with analogue recording. It is trivially easy to record and replay say a 3kHz tone at -105dB on a 16-bit recorder, and have it be perfectly audible. Of course, the ubiquitous nature of 16-bit recording, and the wide availabilty of CD-R, does suggest that anyone transcribing their precious and fragile LPs would use 16/44, which is much more than adequate to capture everything on any commercial LP. -- Stewart Pinkerton | Music is Art - Audio is Engineering |

Dormer faulted me for sticking with the same analysis that I'd used with dozens of other cards. I justified sticking with the same analysis so that the data would be comparable. Dormer has a long and regrettably track record for libeling me. For example he faulted me when his incompetently overclocked cheap-ass computer ate its hard drive. He claims that an alpha copy of my software was on it, which is why it crashed. This was a multi-gigbyte hard drive and my software ran a few hundred kilobytes. Furthermore my software was a straight-up Visual Basic application that did no bit-twiddling with the guts of Windows. I think Dormer was telling a made-up story to impress his peer group on RAO, which includes well-known idiots like Middius. Of course I was right, but that is something Krueger himself wouldn't admit to. Check the google archives. you'll find me admitting to errors on numerous occasions. Has Dormer ever admitted to an error? I don't think so. Dormer's complaint with me is based on the SBLive! sound card which is now totally obsolete. Yet still on sale.

He debated this with me over in comp.sys.ibm.pc.tech maybe a year or two ago when it was more relevant. He got shouted down by the group. That is a lie. Anything I say that you disagree with is lie, Dormer. I did not get shouted down by the group at all. Yeah, sure. One or two CreativeLabs haters persisted in denegrating the Live! and promoting another soundcard to the group Step one, dismiss the people who disagreed with you as being hopelessly biased. others were interested in the results, some posted to the group, and several friendly and productive email exchanges took place. Step two, glorify the people who agreed with you, and cite private communcations that your critics can't possibly see. One person mailed to say he had similar results to mine, but couldn't understand why Krueger refused to keep his website in tune with reality. Step three, focus on someone who decided to ally themselves with you. Dormer's complaint with me is based on the SBLive! sound card which is now totally obsolete. Yet still on sale. Hrm.

Let's put it this way, the Audigy pretty much corrected the problems I found with the Live! that Dormer would like to pretend were non-existent. Here we go again (sigh). The problems with the Live! are well documented, I shall not regurgitate them again. Finally, we get Dormer to admit that there were in fact problems with the Live! That they were audible is apparent from the files anybody can download from http://www.pcabx.com/product/ct4830/index.htm However, it was shown that a driver revision corrected anomalies that affected a previously attrocious sample rate conversion. Dormer ignores the fact that I was told this once before, retested the card, and found no evidence that supported the claim. Please compare and contrast the frequency response curve I posted for my last SBLive! test first posted on 2/2/ 2002 as http://www.pcavtech.com/soundcards/c...ndex.htm#FR_LB and this one http://audio.rightmark.org/test/crea...!5.1-1644.html Which had to be done some years later, as the software used was not relesed until 4 Sept. 2002 per: http://audio.rightmark.org/lukin/rmaa/ I believe this was somewhat after Dormer's big *revelations*. |

The JPGs were made using different analytical software than that which I used for my two sets of earlier tests which yielded similar results for vastly different driver releases. "Different analytical software"? Bleugh!! We both used SpectraLab. As I've explained to you many times, to no avail, the vendor changed how some critical parts of this software worked about the same time Dormer started flogging this problem. The relevant area is SNR, and the differences for the same data can be as much as 6 or more dB. Arny, I used the most current version.. did you not use a current version? As I've explained to you many times, to no avail, there are solid reasons to use software that provides comparable results over a period of time. BTW, the use of JPGs is typical of Dormer's technical incompetence on the web. The screen shots are high contrast with a limited palette. JPG is far from being the ideal format for portraying them. JPG's work fine. It's all about using the best tools in a relevant way. I'm sorry Dormer that you lack the tools to work effectively with common file formats that are more appropriate for the application. JPEGs of high resolution, limited-palette screen shots either fuzz up the detail or involve files that are way too large. The vendor made some significant changes to how his software worked just before Dormer started using it. There were substantial differences in the numbers the analytical software used would generate for the same data before and after the vendor changed his software. Dormer faulted me for sticking with the same analysis that I'd used with dozens of other cards. I justified sticking with the same analysis so that the data would be comparable. This is absolute tosh, and a load of old blather. Thanks for dismissing relevant facts, again Dormer. Earlier, I claimed that you are a blithering idiot who dismisses relevant evidence that exposes your ignorance, and you performed on cue. You say you will stick by data, continuing to perpetuate tired arguments based on that tired old data, even when you are notified that the situation has changed. I've presented my case. Heck, I got 88dB SN/R in tests you got 82dB. A deviation of that size is in no way caused by a minor software revision, particularly something of the calibre of SpectraLab. Except it is. Stop blaming your tools! Thanks for dismissing relevant facts, again Dormer. Earlier, I claimed that you are a blithering idiot who dismisses relevant evidence that exposes your ignorance, and you performed on cue. Dormer has a long and regrettably track record for libeling me. For example he faulted me when his incompetently overclocked cheap-ass computer ate its hard drive. This is an example of Krueger accusing somebody of doing something ("libel"), then acting out the scenario himself. It's quite weird. He litters his commentary with bitterness and hate, as exemplified by the words "incompetently", "cheap-ass" and "ate", in this example. None of it is true. Dormer is so afraid of taking responsibility for what he says that he is now habitually posting with the no-archive flag turned on. Nevertheless, here's a quote of one of his recent posts where he tries to lie his way out of a discussion of this very situation: http://www.google.com/groups?&selm=t...3%40fed1read01 Follow the thread for other quotes from Dormer as he spins his way out of control. |

Consider this: http://www.pcavtech.com/soundcards/L....htm#FR_1644-a What causes the massive 'spike' in frequency response above 20kHz ? I think that's per design. It's part of the *price* they pay for the exceedingly flat response below 20 KHz. The "massive spike" actually is less than 0.2 dB high. Because its narrow and at such a high frequency, it's sonically meaningless. |

Wrong. .wav is a container format, just like .avi for "Video for Windows" and .ogg for some types of open-source multimedia files (eg. audio encoded with Vorbis, Speex, FLAC, and video encoded with Theora). .wav can contain PCM data, but it could just as easily contain MP3 audio data, ADPCM audio data, etc. OK, I'll give you that one! OTOH, when people refer to .wav files for audio, I have never seen anyone suggest that these were anything other than uncompressed PCM. 9 times out of 10 the person means exactly 44.1Khz, 16bit PCM. Well they should say that, or people will think they mean what they write, and respond appropriately. 90% of the population can't be wrong!! :-) Yes they can. :) I wouldn't bother entering Family Fortunes you don't stand a chance :) I don't have the required knowledge.

Most of them are ADPCM, but many are MP3s. I did a batch conversion from PCM WAV to FLAC a few weeks ago. -- Now playing: Will Young - Leave Right Now [128kbps] |

I've handled 'digital disks' since Pontius was a pilot and these DVD Rs and RWs are reet touchy little things - far more so than CD Rs and RWs, IMO...... Burning on a computer burner? As a matter of idle interest, what brands of disk have you tried, and are there any that you find better? How about burn speed? OK, I'll play. Talking only DVD media here, I have found that the 'better' (ie less prone to failure) disks are, without exception, the branded 'famous names' like Philips, Ricoh, Maxell, Memorex, Imation, HP etc. I have not yet had one failure from disks like these. Cheap, unbranded disks that I have tried are Maplins own and PC World's own 'PC Line' - failure rates here were about 3%. The thing to bear in mind is that unbranded disks are very likely to be made by a famous name and that one famous name (Ricoh perhaps the best example) will be producing disks marketted under other 'famous names'. There are a number of free utilities like DVDINFOPro http://www.dvdinfopro.com/ that will give up these secrets, if they are important to you. Massive differences in price mean that it pays to try and 'match the disk to the job' - ie cheap disks for recording/saving dross of the telly (which will very likely be repeated in 3 months anyway) and summat special for a 'one-time only' family event, for example. There is simply no point (unless you are very well-wedged) in paying over the odds to try and minimise 'coaster production' when a failure rate of 2 or 3 % on disks costing only 50 odd pence each will still not approach anything like the 5.99 prices for the same type of disk (with a well-known name) on jobs that don't merit the extra reliability. In a 'batch run' of, say, movie backups it ain't the end of the world to have to do one twice if the cost savings are high enough. It is important to bear in mind also that almost all DVD recorders and players have their likes and dislikes for different flavours of disks and it pays to find this out early in the game. Many online media stores will send a mixed sample pack of media for you to conduct your own experiments. I think you will find that this is much to do with the dyes that are used with Prodisc being a bit of an habitual offender and Ritek being the current 'Golden ********' of the DVD media world these days. For those of you who can detect a 'rosy glow' in various formats (like vinyl, for instance) you might want to match the player/recorder to the preferred disks with a deeper purple dye. (Of course, with vinyl, you could always trying changing yer cartridge for summat a bit more up-to-date.... :-) Anyway, as far as I know, posh, expensive DVD kit is no more immune from this than a cheap jobbie from a supermarket. The DVD forums carry much information on these matters. Fortunately, computer DVD drives seem able to cope with anything you throw at them! Speed? As always, when one is a relatively early adopter, you end up stuck with slower speeds than people who tap in at a later generation. All my kit is oriented to 2x for 'minus' stuff and 2.4 for 'plus' stuff. (No idea what the bitrates are - I see them every time I burn a dsik but I'm suffering from 'unit blindness' these days and don't take much notice!) The new 4x stuff will be with us very soon, if it isn't already......!! Out of interest for anyone who is looking to get into the game, the name Lucky Goldstar (LG) is the one to watch - if you do not need to change Book Type, you will find the LG GSA4040 multiburner (plus, minus and RAM) very hard to beat at about £85 as an OEM unit from places like Dabs.com. Also, there are a string of LG multi (plus and minus) recorders coming out at very reasonable prices like the new DR4810: http://www.whatvideotv.com/news/fram...ws.php?id=5441 http://www.unbeatable.co.uk/CatalogueItem_16463.html As well as the LG 5810-MJC due soon: http://www.techonline.com/community/news/32280 http://www.cirrus.com/en/press/releases/P396.html ....which will be another step toward the better compatability we should be getting from what is*supposed* to be a 'universal format' but which is, yet, anything but! |

The Pioneer 106 is a PC unit I've seen recommended again and again.. how does this compare? Apprently it doesn't matter what you throw at the 106, it will burn successfully.. branded, unbranded, frisbee's.. Indeed, I understand the 106 is a star performer, not sure what formats are covered.... Maybe you can help me out? Play yer cards right and you never know.... :-) I'm looking to get into the DVD archiving game, with a little bit of editing, but I don't want to spend the rest of my life sitting in front of a computer. You don't have to. With kit as it is atm the vaious stages of the operation take about half an hour each pass. You don't have to crank a handle - if you've got summat else to do (within reach, as it were) you can get on with it. Right now, I'm a) ****ing about in here, b) cleaning vinyl, c) listening to (someone else's) excellent vinyl rips on my valve gear, d) smoking cigarettes and drinking tea...... I fancy a standalone - but can you just drop the disc into a PC burner, rip the video, tweak it, and pop it back on? [Type of thing..] Yes. Needs one or two different little software packages according to what exactly you want to 'archive' and where it's coming from (hence a +/-/RAM burner is handy to have)......
