Re: [SlimDevices: Audiophiles] HDCD ripping
In 2005, the 'following thread' (http://forums.slimdevices.com/showthread.php?t=15185) showed up discussing this whole HDCD topic. Bottom line is that the only way to rip HDCD seems right now to be to use WMP 9 or 10 (9 worked for me), use a plugin to capture the 24 bit WAV file, play the songs and use the built in HDCD compander function of WMP 9 to expanded the HDCD compression into 24 bits. Once the 24 bit WAV is captured, you can then convert to FLAC. Slow, but doable.

Re: [SlimDevices: Audiophiles] Linn Records Studio Masters on Tp & SB3
Veggen, Thanks for more pieces of the puzzle, I was just diving into the FLAC documentation myself. We have reports that 88.2 files play but half speed. We also have reports the test files show as 44.1 in some programs. So, I wanted to confirm the tets files as 88.2 so we can know for sure if some of the programs in question are lying or not. Thanks for the input. Linn suggests downsampling to 44.1 then converting to FLAC, not upsampling to 96...

Somewhere in this pile of crap, I have a pinout and circuit for using the PMD100 HDCD chip, but do you think I can find it right now? I can find the pair of chips I have, but not the documents! In any event, it's not quite that simple, because the PMD100 HDCD decoder chips -also- perform the oversampling and digital filtering functions. I don't think you can use them as just an HDCD decoder. The second generation PMD200 devices may be more flexible. For some reason I have it in the back of my mind that they're based on a FPGA, rather than an ASIC. They also need a micro-controller to get them started. My Sonic Frontiers DAC uses a little PIC controller for this. Unfortunately, I have even less info on that chip.

Take both the original data and your list with zeros interspersed, and plot it using your favorite plotting tool. You will see that you are adding a huge amount of very high frequency "signal" that is 100% spurious. To do a 0, 2, 0, 4, 0 requires extremely high frequency, and since real PCM is sinusoidal, it has to have -2, -4, or something close because with sine waves, you have to have negative values to match the positive, unless you have a really big low frequency signal that takes something that is really 0, +1, +2, +1, 0, -1, -2, -1, 0, +1, +2, +1, 0, -1, -2, -1, 0, into something that is positive for a long time. Anything that goes 0, 2, 0, 4, 0 has signals at least twice the frequency of a signal that goes 0, 2, 4, ...

Re: [SlimDevices: Audiophiles] Do you use WAV or FLAC ? Pros vs Cons.....Please :-)
Since we're in the audiophile forum, you can have the server transcode the flac to wav before sending, which would be the same as having wav stored, should you wish to test it. Same as wav, however, doesn't mean different from FLAC, at least not to my ears. One possible difference would be in Sb processor load being reduced, which is likely not audible, or able to affect the life of the hardware. Attempting justification of streaming wav; It seems like power would be demanded by processor spikes in the Sb3, thus robbing it from somewhere further up/down the chain, surely someone here can refute that if need be. Coupled with the notion that an external supply doesn't make a difference, it would seem that internal power is a fairly valuable commodity. I stream wav because I have a wired network and think this stuff might matter (but can't prove it), and store FLAC for reasons everyone else gives. Also, this thread highlights the data checksum in FLAC that's lacking in wav: http://forums.slimdevices.com/showthread.php?t=31257 -- Skunk Skunk's Profile: http://forums.slimdevices.com/member.php?userid=2685 View this thread: http://forums.slimdevices.com/showthread.php?t=32999 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

There are two approaches to upsampling. I'll take an easy example. Assume you have a 44.1khz signal and want to to be 88.2kHz. Also assume that the PCM data looks like 0, 2, 4, 6, 7 for the first samples. To upsample it, you first double the number of data points. 0, 0, 2, 2, 4, 4, 6, 6, 7, 7 Then you can decide if you want to leave the data 'as is' with duplication, or if you want to do some interpolation. You could, for example, do simple linear interpolation, giving 0, 1, 2, 3, 4, 5, 6, 7, 7, 7, Or you could do a higher order quadratic or other functional smoothing. Then to reduce the sample rate, you just throw away data. So to go from this 88.2 to 44.1, you just pick every other sample. this would give you, tada, 0, 2, 4, 6, 7 Now, if you want to widen the data, say from 16 bits to 24, the crude approach is to just add 8 bits of zeros to each value. But adding zeros doesn't address the sample rate. -- Pat http://www.pfarrell.com/music/slimserver/slimsoftware.html ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Re: [SlimDevices: Audiophiles] CD Treatments?
I find that Brasso and other polishing compounds helps with the lighter scratches, but have not had any luck with the deep ones. I've also tried Plexus which fills in scratches in polycarbonate. Again, no luck with the deeper scratches. The most luck I've had with the deeper scratches is ripping with dbPowerAmp and just letting it work away, sometimes for hours ripping one CD. I've even tried various grades of sandpaper. Polycarbonate is tough stuff. Actually the best way is to go on Amazon.com and find a used copy in very good or better condition. That's saved me countless hours of work. It's worked everytime, except for that one Tracy Nelson disk that is out of print is selling for collectors prices.

Re: [SlimDevices: Audiophiles] Linn Records Studio Masters on Tp & SB3
What the Linn man is saying is correct, flac has standardized codes for the most commonly used sample rates, but it can support any sample rate as described below. >From the flac site: http://flac.sourceforge.net/format.html "Again, since a decoder may start decoding at an arbitrary frame in the stream, each frame header must contain some basic information about the stream because the decoder may not have access to the STREAMINFO metadata block at the start of the stream. This information includes sample rate, bits per sample, number of channels, etc. Since the frame header is pure overhead, it has a direct effect on the compression ratio. To keep the frame header as small as possible, FLAC uses lookup tables for the most commonly used values for frame parameters. For instance, the sample rate part of the frame header is specified using 4 bits. Eight of the bit patterns correspond to the commonly used sample rates of 8/16/22.05/24/32/44.1/48/96 kHz. However, odd sample rates can be specified by using one of the 'hint' bit patterns, directing the decoder to find the exact sample rate at the end of the frame header. The same method is used for specifying the block size and bits per sample. In this way, the frame header size stays small for all of the most common forms of audio data." So a 88.2kHz flac can be made if they are willing to understand how to do it. But, what is the problem with resampling to 96kHz, and then converting to flac? I really doubt you will be able to hear any difference, and its fairly quick to do anyway. -- Veggen Veggen's Profile: http://forums.slimdevices.com/member.php?userid=7035 View this thread: http://forums.slimdevices.com/showthread.php?t=32951 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

This is not about downconverting. HDCD decoder dynamically builds the "final" signal using standard CD data as a base, and additional HDCD information. What I think about is to do the same thing just once, on a computer, resulting in 24 bit wav file that represents finally decoded HDCD recording. Not sure it's possible, but that would make sense to me. On CD you're limited to 16bit, so you have to do it dynamically.

To go from 96kHz -> 44.1kHz the ideal approach is to first upsample by a factor of 147 then downsample by a factor of 320. The upsampling involves simply adding zeros after each data point to pad the data out - 146 zeros after every data point. This leaves the frequency content unmolested over the bandwidth of the original signal. An anti-aliasing low pass digital filter is then applied to remove all the frequency content of the signal which can not be retained at the new sampling rate. So for a final rate of 44.1kHz you'd choose a cutoff frequency of 22.05kHz or lower. Then finally, you discard samples at the downsampling rate which in this case would mean retaining 1 sample in each block of 320. I'm not sure whether this method is used where real-time resampling is required due to the amount of data generated by the high upsampling factor.

1 - FLAC files are smaller. Spend less on discs. 2 - You can save network bandwidth without having to transcode from WAV to FLAC at the server. 3 - You can get more esoteric tags in if you want to (eg ReplayGain, multiple Genre values, unusual tags like "Composer" or "Conductor", nonstandard tags like "Performer"). Of these (1) is important to me (it means I can manage with one disc instead of two for my main library) and (3) is absolutely essential (I could not manage without multiple genre values).

HDCD's (ripped or raw) generally sound fine and even better when going through an HDCD DAC. An HDCD will usually have a lot of care put into its production mastering. I've never heard a "bad" HDCD (regardless of whether the DAC was HDCD capable or not). They certainly don't sound hyper-compressed and there is no point in trying to "downconvert" an HDCD wav to non-HDCD thinking it will sound better. It will sound the same...unless you have an HDCD DAC in which case it will sound worse than it might because you have just pointlessly removed the benefit of HDCD. I have 50+ HDCD's. I don't have an HDCD DAC at the moment. The next DAC I get will certainly have HDCD - I miss it more than I expected. I live in eternal hope that we might get 24-bit masters to download in the future - which would render HDCD irrelevant. -- Phil Leigh Phil Leigh's Profile: http://forums.slimdevices.com/member.php?userid=85 View this thread: http://forums.slimdevices.com/showthread.php?t=32967 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Re: [SlimDevices: Audiophiles] CD Treatments?
I have used Auric Illuminator. It's basically a high quality wax that fills in imperfections in the CD surface. It's pretty easy to apply and the CD ends up looking nice and shiny. I started out applying it religiously (pun intended) to my CDs when I still used a transport, but slowly lost interest and didn't really notice any difference in sound quality whether I used it or not. It is good for repairing lightly scratched discs and cleaning smudged discs, but doesn't really do anything for discs so heavily scratched that EAC has trouble reading them. As noted, it won't make any difference when ripping on your PC unless you have thumbprints or other debris on the discs.

Re: [SlimDevices: Audiophiles] CD Treatments?
For a CD in reasonable condition you will not need any treatment. If you rip the CD, the ripper will either get a bit-perfect copy or it will not. EAC will re-read many times if necessary to try to get a verified read. If the treatment is able to take a damaged CD and make it such that the ripper can read it perfectly, then it is useful. That would be the only circumstance under which it is useful, IMO. I suggest that you try to rip using EAC, and if EAC cannot read a specific CD then try to clean it, treat it, or whatever. IME, very few CDs will need it, if you have taken reasonable care of them.

Thanks, that was fascinating. It was beautifully filmed, the 'transported while listening' montage reminded me of sophia coppola's lost in translation, but good. The subject matter took on a Christopher Guest like mockumentary tone on its own, so I'd imagine he could have a ball with this sect. Beyond humor, the psychology behind it all is fascinating.

That VCR left a huge impression on me, so now I am the type of audiophile who wants to achieve better sound than masses, but with limited expense. I don't want to have to fib about component prices to hide my dysfunctional behavior. When the factor of time spent was added, however, the cost was multiplied exponentially. Did you see the poor guy's daughter? She looked like she wanted to cry!

The reason that simply chucking away every other sample when downsampling (eg. as happens in a Squeezebox) rarely causes an audible problem is because there is usually very little energy in the 24kHz to 48kHz region in the first place, so the aliasing artifacts are very low in amplitude. -- cliveb Performers -> dozens of mixers and effects -> clipped/hypercompressed mastering -> you think a few extra ps of jitter matters? cliveb's Profile: http://forums.slimdevices.com/member.php?userid=348 View this thread: http://forums.slimdevices.com/showthread.php?t=32958 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
