Guest Anonymous Posted January 1, 2004 Report Share Posted January 1, 2004 I just bought a Sony MZ-N1 recorder with NetMD technology. The software provided with the recorder (OpenMG Jukebox + simple burner) gives possibility to import files in LP2 / LP4 standard, but the quality of sound in LP2 is not satisfying. Is there any way to import mp3 files without losing its high bit rate (for instance 192 kbit)? Is recording in SP mode available only through the line/optical cable? Can anyone suggest a method (if there is any) of importing mp3 files in SP mode? I don't have an mp3 player Quote Link to comment Share on other sites More sharing options...
mojo1287 Posted January 2, 2004 Report Share Posted January 2, 2004 The sound quality of an lp2 minidisc is quivalent to a 132kbps WMA file, which is in turn equivalent to a 264k mp3, which is higher than 192 so there is no real loss of quality.. However, Sonicstage can copy in SP; download that. And please don't post the same thing everywhere.. Quote Link to comment Share on other sites More sharing options...
mAjEsTiC Posted January 3, 2004 Report Share Posted January 3, 2004 SonicStage/OpenMG can transfer in SP mode but it is not true SP...just a phantom LP2 track that gets recognised as an SP track on the unit...i.e you don't get the full bit rate of SP but rather you get a higher bitrate LP2 track (as SonicStage/OpenMG encodes in ATRAC3 format that the LP modes use and not just ATRAC which SP uses...) so yes the only way that you can get true SP is to record in real-time...

Guest Anonymous Posted January 4, 2004 Report Share Posted January 4, 2004 Thanks a lot for your anwsers. However in OpenMG Jukebox ver. 2.2 there's an option to register a file to the playlist without format conversion (tools / options / import / file format after report setting). Then we can change in "MD properties" window the recording mode to Stereo recording. Is that true SP? Btw - why wmv format has a 'doubled' (in comparance with mp3 format) bit rate ? If I record an mp3 file with bit rate 192 in LP2 mode, I wont lose it's quality? I wanted to download Sonicstage, but I didn't manage to find it ... Links from the topic "holy grail was found " or sth seem to be broken :/ Do you know any urls where I can find SonicStage? PS Sorry for posting in two different topics - I was desperate to find a solution Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted January 4, 2004 Report Share Posted January 4, 2004 majestic: Is the method of SP recording in Jukebox 2.2 which I've described the same case as "not true SP" recording in SonicStage? If it is, I guess there's no point of downloading SonicStage. and about that the higher bitrate LP2 track... what's its the bit rate? If an LP2 recording can provide the sound quality of a 264 kbps mp3 file, there's no problem. But why is the bitrate of a WMA file equal to the doubled bitrate of an mp3 ?

Guest Anonymous Posted January 4, 2004 Report Share Posted January 4, 2004 I know that ATRAC3plus 64 kbps is moreless the quality of an 128 kbps mp3 file... unfortunately I was not able to find any info about ATRAC3 - mp3 quality relation neither on minidisc.org nor ATRAC Sony's site (http://www.sony.net/Products/ATRAC3/overview/index.html). According to the given tables, ATRAC3 132 kbps recording is in fact ATRAC3plus 132 kbps recording ( which is not true I guess.. Something's wrong with these tables :shock: Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted January 4, 2004 Report Share Posted January 4, 2004 mkay, from my today's research: 1. When you transfer the file in SP mode using Jukebox / Sonicstage it is converted to LP2 stereo and then it is copied to your minidisc in SP mode, so in fact it still is an LP2 recording, just the method of file transfer to your minidisc is SP. Hence the quality of such a file is still nothing else than LP2... 2. Tests show that ATRAC3's 132 kbps recording quality is higher than 128 kbps mp3 file... However I was not able to verify whether LP2 132 kbps is an equivalent of 132 kbps WMA file. I didn't find any info on WMA - MP3 relation either (the only thing I found was that 128 WMA file sound quality is better than 128kbps MP3 file). Mojo1287: Where did you get that info from?

Guest Anonymous Posted January 4, 2004 Report Share Posted January 4, 2004 btw, I've just listened to the same track encoded in mp3 @ 320 kbps, 192 kbps, 128 kbps and ATRAC3 132 kbps the difference between mp3 file with bitrate 192 kbps and ATRAC3 132 kbps file was quite significant (of course mp3 was better...) while the difference between mp3 @ 128 kbps and ATRAC3 was small (this time ATRAC3 format had better quality) for the test I was using Sennheiser HD 580 headphones Quote Link to comment Share on other sites More sharing options...
pepsi_max2k Posted January 6, 2004 Report Share Posted January 6, 2004 hey, i just got a minidisc player so i dunno what i'm talking about :shock: anyway... tried to use realone to transfer tracks onto the disc and it looks like it'll only do it in atrac3 132, 105 and 64kbps. is there a way to get it to transfer in the sp mode or do i have to use sonicstage for that. and what's the 105kbps all about, i know 132 is lp2, 64 lp4 so is the 105 some kinda lp3? and which is better to use anyway, realone, sonicstage (checkin/out boooo :roll:) or the nero + simple burner thing.

Guest Anonymous Posted January 6, 2004 Report Share Posted January 6, 2004 You've got plenty of stuff here: http://www.minidisct.com/md_record_mp3.html If you want to record in SP mode (doesn't matter if you want to record mp3s, wavs of whatever) you have to do it in REAL-TIME. There's no other option... The SP recording offered by openMG Jukebox / sonicstage is not a a true SP recording - the quality of such a recording will be equal to the quality of LP2 mode recording - 132 kbps. If you want to record your mp3s in SP mode, you'll have to do it in real-time using, for instance, 'MP3 2 minidisc' application (you can dl it from http://home.online.no/~hpersett/mp32minidisc/main.htm). I suggest connecting your minidisc to the computer via optical cable, since the standard mini-jack cable produces too much distortion.
