Re: MD: Future of minidiscs
- Original Message - From: "Dan Frakes" [EMAIL PROTECTED] OK, but the problem is that all of the above is a CD vs. MD sound comparison. I agree that MD doesn't sound as good as CD. However, your original claim, to which I was responding, was that high-bitrate MP3 sounds better than MD. Well, what I wrote was actually directly in response to someone else's claim that "MD always sounds better than MP3s". I was merely describing a simple test that compares CD vs. MD because, essentially, when I rip MP3s I don't get the strange sparkly burbling sounds. If you want to round out the experiment a bit more, then just do this instead: . Get a digital optical output card for your soundcard . Play an audio CD in your CD-Rom drive thru the soundcard (using digitial SPDIF connector from CD-ROM to soundcard) and out thru the optical output and monitor that on your Sharp831 using Rec-Pause mode . Record the audio CD from the second step on the Sharp831 (just take it out of Rec-Pause) . Play back the MD you just created . Encode the CD as MP3 using what you believe to be a high-quality encoder (e.g. 320kbps encoded using LAME or Fraunhofer) . Play this MP3 thru your soundcard and out thru the optical output and monitor THAT on your '831 in Rec-Pause. The MD sounds the worst of the bunch because it adds the artificial fizzing sound. Yes, it's perhaps a little subjective, but when you define 'low quality' to mean 'sounds artifical because white noise is not recorded well and instead sounds like a small jet of bubbling steam, as do complex sounds like cymbals and essonance' then my experimental results seem (to ME) to show that the MD recorded on the Sharp 831 is the lowest quality of the three. The 831 adds a layer of sparkly, burbling high frequencies to quiet passages and high frequencies .. in fact, if you record anything with a slight amount of background noise onto the 831 the background noise just sounds crazy and artificial like a load of bubbles bursting instead of dull white noise. DON'T come back at me by saying 'You should get a better CD collection if all the tracks have background hiss' because I'll just tell you where to go. That's my CDs, and the 831 cannot encode them as well as a Aiwa model at half the price, or a Sony deck, or ... As for the above paragraph (and this is completely unrelated to the previous debate), I've never heard of any kind of "layer of sparkly, burbling high freqencies" or the like when recording from CD to MD. The MD never sounds as good on my equipment, but never because of such "noise." To me that sounds like a problem with your recorder. I'm not the only one !! I just did a quick search on altavista and came up with this: http://minidisc.org/hearing_sharp_atrac.html Although I did also find this as a kind of response http://minidisc.org/hearing_sharp_atrac.html Is it a problem with my Sharp831; or is it a problem with THE sharp 831?

My guess is that the difference would be at least as big, if not more so, if I were using an MD player with digital out, since the D/A converter on the receiver is probably better than the one on my MZ-R50. To really do it right not only the listener but even the person selecting the music must not know which is which. This is easy with drugs, but may prove impossible with an MD VS an MP3. The other thing that makes these A/B tests very difficult is that you need a way to perfectly balance the volume.

Here's the test I did and it's inCREDibly simple Granted it isn't particularly scientific, but that doesn't mean it should be debunked instantly. 1. Put a blank MD in your Sharp831 recorder 2. Connect the optical digital IN on the 831 to the optical digital OUT of the CD player 3. Put in a good CD with lots of dynamics, quiet bits, and high frequencies, and if possible a little background noise. Something recorded live rather than overproduced, so something like A Minor Forest, Do Make Say Think or Mogwai, rather than Future Sound Of London 4. Set to Rec-Pause and monitor to the audio coming out of the CD player source 5. Record the track onto minidisc 6. Play the track back. Which factors change? As far as I can see only: 1- Whether the audio is direct from the source CD or from the MD copy 2- Whether the 831 is postprocessing the MD audio differently than Rec-Pause monitoring I can rule out 2 because: I did the same test on a friend's Aiwa player and the differences (whilst still there) were less pronounced, and then I played that MiniDisc on my 831 player and did a blind A/B/X test to compare it with the one I recorded on my 831. Guess what? My 831 lost every time. I have never seen a discussion about this and it has never come up so I am not sure which of the following is the case and also not 100% sure I fully understand your statement above with regard to the means you used to monitor the sound. First, does the sound coming out of an MD player while the MD is being recorded, come from the MD or is it just a straight pass through. In other words like the difference between a one head and a two head cassette recorder? I don't think that the sound you hear while you are doing the actual recording is coming from the MD since that would require the laser to be recording and playing at the same time. This statement applies if I interpreted how you did your test correctly. If I am correct about not being able to monitor the actual output of the MD itself while it is being produced and that's what you are saying you did in your test, then ATRAC has nothing to do with the difference in sound quality you are hearing. If I misinterpreted how you did the test, please correct me. The 831 adds a layer of sparkly, burbling high frequencies to quiet passages and high frequencies .. in fact, if you record anything with a slight amount of background noise onto the 831 the background noise just sounds crazy and artificial like a load of bubbles bursting instead of dull white noise.

I just threw that in to see if you were on your toes. But there is a DAC at the end of the chain for the MD. The quality of DACs can vary greatly. I'm sure that you know they make stand alone ADC and DACs that cost more then most people's entire audio system. These are not for consumer use (unless you are really, really into music and super wealthy). My CD player is fine, thankyou. No really. What, you actually think a CD player uses an ADC between the audio source and the digital optical output? Are you mad? And hey, I get exactly the same results no matter what CD drive I use, or whether I use the optical output on my SBLive Live Drive II, or if I use conventional analogue in, or ... No, please believe me, I have tried SO MANY different sources. What, they're all broken? Broken, no. The quality of ATRAC compression can vary greatly. Both MP3 encoders and ATRAC encoders have improved since their inception such that almost any modern MP3-encoded file will sound better than a MiniDisc recorded using a version of Atrac that is a couple of generations old.

Re: MD: Future of minidiscs
Dear sir, i do like the minidisc for its size and quailtiy however, portable mp3 cd players have been introduced. I like the fact that i can now burn up to 8 hrs of cd quality music to one CD Sir you incorrectly state that an MP3 file will produce CD quality music. The quality of MP3 files can vary greatly. But one thing that I am fairly certain about is that the quality of a true digital copy of an original (prerecorded CD) to an ATRAC encoded Mini Disc is superior to that of MP3 . I agree that the storage is a significant factor and that for the vast majority of people the difference in sound quality between MP3 and digital transfer Mini Disc is not as important as the extended time. But the fact still remains that MD is superior in fidelity when compared to MP3. Sony and others have just announced MDLP products (see the MDCP news), these can provide 5h20m of stereo playback at "reasonable" fidelity (not much has been reported about MP3 vs. ATRAC3 quality at 66kbps yet). Until certified A/B double blind listening tests have been performed it is impossible to say who the quality of the new ATRAC3 encoding compares to MP3 files transferred to a CDR(W). MDLP can be seen as the MiniDisc's [current] answer to MP3. Should the walls of RIAA and SDMI someday come tumbling down, I am sure there might be other, more interesting MD/MP3 (or at least open ATRAC) synergies. As Rick has stated, I think that the consumer electronics industry in general is waiting to see if legislation will be passed permitting the downloading of copyrighted music. It is very possible that some agreement will be reached. But I feel strongly that there will be some cost to the consumer paid to the copyright holder. Such as the few cents that are supposed to be added to compact cassettes. In spite of of the terrible disappointment regarding the growth of the Mini Disc format in the United States (it remains a huge success in Japan), if this whole MP3 thing is eventually worked out, I think that we may see new growth (certainly the door would be opened for growth potential) in the MD in the US. I do not see static RAM (for example Flash Cards) as a realistic means of storing music. Although they offer the advantage of totally eliminating the skipping problem (when shaken) I do not realistically see them as anything more then a temporary means of storing songs. The price is way to high and will continue to remain so. It is important not to confuse photographs with music. Flash cards are great for use in digital cameras. They are not intended for anything but temporary storage. Since digital images will require a computer or hard copy, the object of the flash card is to use on the "road" and then to transfer to your computer (CDRs are a great place to store them). With the advent of direct memory to computer transfer using USB (either through newer camera or the quite inexpensive card readers (e.g. SanDisc's is only $30) copying images takes only seconds. Music on the other hand must be stored on something very portable and inexpensive so that you can build up a library. You don't need computer to listen to music. Just a player. You want to be able to carry with you as many songs as you feel like and play them at will. Even with the larger CD, you can still carry dozens of them with hundreds of songs in a relatively small space and weight.
