OK, now it looks like that I finally finalized my first experimental draft of FM recoding setup. The AD122, outputting the 24/96 stream, into PC’s uncompressed WAV files via Lynx 16 interface. For the time being I decide to use the DA924 as D/A. With all beauty of DA924 I did not fine it comfortable to handle CEC TL0 and I feel that Bidat does better in there. (Although Bidat vs DA924 is VERY big and VERY separate question). Ironically when the DA924 run the “narrow lock” after the AD122 it perfumes very nice, primary, I think because the FM has no UHF information to begin with…

Anyhow, it looks like all is set here and the only thing that I need at this point is a recording software that would accept any OLE or COM or COM+ or .NET interface as I would like to activate recording process by sending email… Alternatively I might tonal it via VPN but full remote automation sounds more desirable.

The programming on December looks very nice and the hard disk space is cheap...

I’m happy pussy!

How came that I can’t write a file longer then 2G? As I remember form past, the FAT partition had limitation of 2G but my drives are NTFS formatted and it should not be an issues. Perhaps a WAV file has by nature 2G limits, doesn’t it? If this is the case then it is not good as 24/96 eats a lot of hard disk space. Any solution? The entire idea to record for instance an opera “live” that later on if you are “in a mood” then you could experience it "live", without flipping those records, without changing those disks or without reloading those files…

Hi Romy, That would be a very interesting comparison. How about a new thread?

Can you describe how your vinyl playback and conventional CD playback fall short of what you are getting from FM?

Guy, you are asking a resemble question but what do you expect me to say? Do you expect me to convince you (or myself) that FM is totally different (including many “hidden” not obvious reasons) and way more advanced media then recorded music? Would I need to do the convincing? You see, a lot of people out there talk about audio with one or another level of authority and credibility and I very frequently approach to all that “taking” with very high level of skepticism. Why? Because I have seen and heard the actual results that the people are getting out there while they run this months. Probably I would approach with the same skepticism my own comments about the FM… until I had the tangible evidences that were able to assess by myself.  Therefore instead of reading my comments about the vinyl/CD vs FM how about I send you a WAV file with one of my recent recordings, no mater how premature those recordings are… There is a catch in here. Since I started my FM paranoia and have quite a few people connected me, some of them sent me the examples by my request. Thos people do claim that FM is very good but not at the point of my exuberant glorification. I agree with them because a have heard thier files and because none of them demonstrated any interesting (from my prospective) FM sound. I do not know why I have better result even at 20/44, but I do like my result better and in a way “different”. Anyhow, all that I might propose is send you a file and it you have a good sound digital interfaces would be the judge. Send me your address and feel free to share with other your finding after you listen the recording.

Is the FM playback of 'non live' material still sounding better than your vinyl and cd?

Yes, it does. Most of the time when the stations broadcast well and use good sources.

Have you tried recording vinyl with the Lavry?

Nope, I did not.

I shall be trying a low budget experiment along similar lines tomorrow burning a cd directly from a live BBC Radio 3 concert (from the Leak tuner)via a relatively cheap Tascam CD Recorder. It will be interesting to see how much of the 'live' FM quality is preserved by this machine. Obviously it's not 24 96 standard but I'm interested to see whether the good aspects of the FM transmission are still preserved.

I am VERY skeptical that you might get any interesting result form it. You see, what I found so far, that as soon you put the uncompress VAW file to CD and convert it into whatever format the CD burners could accept then sound flying away form this recording with the speed of light. Record it to uncompress file and play it form there. DO NOT dump it to CD…

Romy, What is the possibility of just dumping the wav files to cd as a data disc? Not as a red book audio file, just a copy from your HD. Or, we could just start sending you our spare hard drives for data dumps, I have two 30 gigs laying about uselessly. Or maybe a dump to DVD formatted discs, as the gamming mags do, to allow 4 gig on a CD. It would be nice to have a playable format in our CD players but we might be able to manage.... Bud

Hi, Max.

When you say “WAV file X burned on CD-R” then the question would be what was the source of those files? If you have a row source with some kind of A/D and if you intend to stay with 44 then 44/20 is OK format, do not stay with for 16 Bit. However, if source for your files are other ripped CDs then it is more complicated because it is severely compromised from beginning. 

My transport (CEC-TL0) reads better quality then my CD-ROM. (The CD-ROM is selected among 22 of it’s competitors – do not ask me how it happed – it did happed). So, on the scale of quality I would put this hierarchy with the best atop:

1) Direct feed, A/D writing WAV files and then to play them
2) CD readers (from TL0)
3) WAV file burned from other CD
4) CD played directly from CD reader

Anyhow, if you have an abstract 16/44 file, regardless of the source, then what would be an optimum configuration to do it? I think the fist thing you need to decide how much hassles are you wiling to endure to play 16Bit files. Lynx AES 16 is fine and there are a number of other good external DACs out there but …it is still 16Bit! I presume that nowadays it would be possible to find a good 16Bit on-board DAC. I really do not know what it out there and I did not make my own research in the subject. I went for “big” external DAC because the  “comfort” was not my objective. So, in my case it is a dedicated DAW with Lynx interface, externals DAC, grounds, ugly playing software and so on… I defiantly would NOT go for it is I use the ripped CD  16-bit CDs as a source….

So, after I successfully failed to say anything meaningful to your first question let go for the second one…

I do not know anything about any other lossless formats, I used only WAVs. I would refer you to Lynx manual (or to the manual of any other card you might pick). BTW, Lynx has very friendly and very knowledgeable support team and they are very nice on a phone… Lynx has also the same class card only with built-in premium DACs on it. They claimed that the DACs as very good but I personally do not know if it is correct. Ironically the card with DACs cost the same as a digital interface with no processing on the card.

Hence, generally I do not know what to answer. I had very limited exposure to the subject (well documented with this site). Still, even my extremely limited exposure was 2 years back and it is a LOT on digital world. I heard that nowadays even the head-held devices or laptops with premium audio cards could do good 16bit. I heard that some people use even consumer sound card or pro-video processing machines and get good 16Bit of them

Max, perhaps I wrong but I do not remember you as a me-like-psycho who has interest in “abstract” audio. I hardly feel that juts ripping CDs and play then from DAW would require anything “special”. At least it was my experience… General rule that I would follow is making DAW as “complex” in term of quality and extendibility as your CD playback… I think it would make sense…
