RE: MD: MP3s
Thanks Dave, I downloaded Lame encoder and RazorLame and they work great: I can re-encode my MP3s in one pass (MP3 to MP3). A 25 minute radio show took about 90 seconds. I burnt it onto a CDRW in another 90 seconds, and it worked. I've got another 80 episodes to do now The reason I don't play out directly from the PC is that my soundcard (or WinAmp) sometimes stutters. Also, I don't want to tie up my pc for that long! jim -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Dave Hooper Sent: 28 June 2001 17:23 To: [EMAIL PROTECTED] Subject: Re: MD: MP3s LameBatch should do the job ... it's a front end onto the lame encoder/decoder and I'm pretty sure it can do this sort of thing. You'll probably need to do it in two passes though, first time through converting all the mp3s into .wav files and then reconverting the .wav files into the correct .mp3 files. Why can't you just record the MP3s onto your minidisc through your PC soundcard output though? The loss of quality going through analogue is VERY unlikely to be noticable when what you are recording is only low-quality MP3 files.

MD: Sony and their damned end search...
Well, I just found that my MZ-R70 wrote silence over about an hour of material because the record got inadvertantly pressed as I took it (and it's Severed leather case) off of my belt for the night... For some reason, maybe low battery, it stopped short of wiping the entire disc, but since these tracks were a compilation off of LPs, it will take an afternoon of work to replace them Sony could say that there are many ways to prevent inadvertant erasure, but each of them involves it own kind of frustration. One way to deal with the prolem is with the Hold switch, which would be a good solution since I always use the remote EXCEPT for one thing: pressing stop to charge the battery. (It complains if hold is on.) The wriite protect tab is another possible solution, but I get annoyed at getting protect messages from my home deck when I DO want to change the disk. The correct solutuion, which Sony FINALLY implemented, but not soon enough to fix my recorder, is make the record start position selectable. An even better solution would be to do what everyone else does and just eliminate End Search entirely. Sorry to rehash this old discussion thread. But I just had to do something to lower my blood pressure after wiping out all that work. I am generally a loyal Sony customer, but this type of thing makes me want to throw the MZ-R70 in the trash! - To stop getting this list send a message containing just the word unsubscribe to [EMAIL PROTECTED]

Re: MD: MP3 downloading via NetMD
Eric Woudenberg, Minidisc.org Editor wrote: Yes, it makes me wonder how much work will be involved to get an MP3 track downloaded via NetMD. In theory, you should be able to convert a .wav file to secure ATRAC, right? (Or will you have to have your own real CD to make ATRAC files?). So, since you can make .wav files from MP3 files, why not an MP3 to secure ATRAC convertor and downloader, all running in software, with no change to the NetMD based recorder? The thing that makes me worry about NetMD is that if the above is true (you need software to do the conversion), MiniDisc will become platform-dependent. That is, in order to be able to use NetMD, you need software written for your computing platform. It is my experience that MD is far more popular among Mac and *nix users than it is among PC users (that's not saying there are *more* Mac or *nix MD users... only that the proportions of use are larger in those groups of people). The fact that for a time there were so many more MP3 encoders/players and Napster-like clients for Windows and so few for other platforms probably had a big role in that (there are plenty now, but early in the MP3 craze, there weren't). Regardless of the reasons, MD is quite popular among non-Windows groups, especially Mac users. Sony has historically been clueless when it comes to non-Windows products and software. It took them over a year of saying no, our MD recorders are not compatible with Macs before they finally plugged a Xitel in and realized that it worked from Day 1. Likewise, the software for all their Music Clip-type products (the ATRAC encoding/transfer tools) is Windows-only. Now that they are moving towards MD equipment that looks like it will need software, I hope they take their proverbial heads out of their proverbial behinds and make sure that they make this new format/feature available to everyone. The amount of time it would take them to write Mac and *nix tools would be miniscule compared to the amount of return they would get. - To stop getting this list send a message containing just the word unsubscribe to [EMAIL PROTECTED]
Re: MD: Sony and their damned end search...
Of course you'll get no argument from me, Timothy. Nothing in the instructions for Sony portables with manual end searching warns a user to put the hold switch on, press the END SEARCH button, open the write-protect, or just remove any disc first when leaving the unit unattended. The last two would not have helped when manual end searching ruined a track on my R3 because my finger slipped and pushed REC instead of EJECT (I'd been editing the disc, so the write-protect had to be closed), and I doubt that the hold switch would help when an R55 goes into poltergeist record mode. Manual end searching came in with the MZ-R2. Its manual touted default recording from the current point as a feature, for surely it is what people will usually want to do (!); afterward it discussed pressing the END SEARCH key in order to append instead of overwriting as an available function for the rare occasions when one might want to do such an odd thing. I was quite glad to see that the R900 not only has automatic end searching selectable (yet not the factory default; admitting error is as hard for engineers as for lawyers) but also has REC and EJECT well separated from one another, operating in different directions on different faces of the unit. In fact, EJECT is all by itself, so if you miss it you can't possibly press or slide something else instead. - To stop getting this list send a message containing just the word unsubscribe to [EMAIL PROTECTED]

MD: MP3 to ATRAC
I started playing with some code to convert MP3 directly to ATRAC3. All in all, the results are terrible. While at a high level, MP3 and ATRAC3 use similar approaches (subband audio coding), the actual implementation details are such that the conversion is extremely poor. Why? Both MP3 and ATRAC3 depend on the same digital signal processing techniques. Unlike analog processing which occurs in a continuous flow, digital processing must be done on discrete chunks (frames) of signal data. The division of the data stream into frames introduces errors at the frame boundaries. These errors can be hidden and cancelled out in the decoding stage, but only if a properly matched decoder is used. MP3 (typically) uses 576 samples per frame, while ATRAC (typically) uses 512 samples per frame. As such, the portion of the audio spectrum represented by each sample is different. Also, MP3 and ATRAC use different overlap and window functions to trim the signals at the frame borders. This means that very different noise characteristics are present in each system. Stop reading if you're not interested in the gory details... My code attempted to pull out the 576 MP3 frequency-domain samples and reallocate their energy into 512 ATRAC frequency-domain bins, with a portion of the energy being allocated to a subsequent frame. Note that there's a huge ambiguity introduced here: the signal started as 576 time-domain samples (13.06ms). In the frequency domain, you don't have any time positioning info any more, so all of the frequencies present in the spectrum are smeared equally across all 13ms of the frame. Now you try to allocate this into a 512 sample (11.6ms) frame. 1/9th ((576-512)/576) of the energy of the 576 sample frame doesn't belong in that particular 11.6ms frame, it has to be subtracted out and shoved into the next frame. Great, but this not only reallocates the desired signal, but also the noise. Here, even if ATRAC and MP3 used identical filter architectures, you still wouldn't be able to cancel out the noise since it's just been mangled in the spectrum reallocation. Anyway, to make a long story short, the best way to convert from MP3 to ATRAC (or any other compression format, for that matter) is to fully decode MP3 to PCM and then re-encode PCM to the destination format.

Re: MD: MP3 to ATRAC
my guess is that if sony is smart enough to make the usb connector to x-fer files directly from the computer they will make it work with all the codec's on your computer to encode before it copys the files over, kinda like thier music stick stuff works now. i doubt (or at least hope that they dont do the following) just give you a coded so you have to re-enocde them all of your files. but this is all speculation. anyway what i'm waiting for is when they come out with the replacement for my car unit the 800rec that has netmd on it so i can have my laptop sitting there pop the cd into it, plug the usb cord into my head unit, and copy from my laptop while i'm driving..can anyone say accident. hehe i have enough trouble when i have to edit md's now with the 800 while i'm driving. - Original Message - From: I Can Not Tell You [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Saturday, June 30, 2001 12:51 AM Subject: Re: MD: MP3 to ATRAC snip Anyway, to make a long story short, the best way to convert from MP3 to ATRAC (or any other compression format, for that matter) is to fully decode MP3 to PCM and then re-encode PCM to the destination format.
