makesmiles Posted February 25, 2004 Report Share Posted February 25, 2004 :wacky: I need some advice on a problem recording with a new Sony MD, model MZ-N510CK, please. I have been trying to record the Bible in MP3 files to my MD. When it transfers, the sound is heard in double or triple time...sounds like Donald Duck. The MP3 files on my PC and CD play okay, so I know the files are good. Also, MP3 music records to MD just fine. Other speeches in other formats are okay also. I have tried several other downloaded radio messages in MP3 format and they record in "fast" sound also. I have tried all I know to do (I am new to MD) even contacting Sony Tech Support. Sony said the MD was defective, so I returned it to Best Buy and got another one. It didn't solve the problem. The results are the same. Does anyone have a solution?

The_Stamp Posted February 25, 2004 Report Share Posted February 25, 2004 hmm.. i know theres an option in openMG (perhaps sonicstage) that you could change the pitch of a sound during playback, but i never heard of it transfering over such a way. also, i know that if you play an LP@ or LP$ recording on a minidisc that doesn't recognize such formats is will sound like you described. perhaps your minidisc is defective.

makesmiles Posted February 25, 2004 Author Report Share Posted February 25, 2004 Thanks for the reply. I don't think the MD is defective. I returned the first one and got a new one with the same results. MP3 music plays just fine as well as other types of files. It's just the MP3 speech files that I am having problems with.

Guest NRen2k5 Posted February 26, 2004 Report Share Posted February 26, 2004 The problem is that Sony is braindead, and like a bunch of amateurs, didn't put any code in their software to determine the sampling rate of input files. The MP3's you are having trouble with are going fast because they're sampled at less than 44.1kHz. The solution is to decode them to WAV's, resample the WAV's to 44.1kHz with something like Naoki Shibata's SSRC software, and send the WAV's over NetMD (or burn audio-CD's from them and record the CD's to MD).

makesmiles Posted February 26, 2004 Author Report Share Posted February 26, 2004 :smile: Thanks for the info. You're right, they are sampled at 32khz. However, Sony Tech Support claims that 32khz will work. I'll try your idea and let you know the outcome. Is there a way to convert the wav files back to MP3 at a higher sampling rate so I can get more files on one MD? Thanks again Quote Link to comment Share on other sites More sharing options...
Guest NRen2k5 Posted February 28, 2004 Report Share Posted February 28, 2004 WAV's and MP3's take up the same amount of size on MD, because when you transfer them, Sony's software transforms them into ATRAC3 files at 66 or 132kbps, no matter what the original file was. So, encoding the WAV to MP3 before trnaferring is pointless (and harmful to the sound quality, at that). Have a nice day. Quote Link to comment Share on other sites More sharing options...
