RobA Posted October 14, 2005 Report Share Posted October 14, 2005 Can someone provide me with a sample of 48kbps music? I would like to know how it sounds. Quote Link to comment Share on other sites More sharing options...
pata2001 Posted October 14, 2005 Report Share Posted October 14, 2005 It's just bad. Dont' bother. The only good use for it is probably voice recording.If you want, you can encode your own with SS2.x and up. Quote Link to comment Share on other sites More sharing options...

How much different can it be? Only want a sample. Quote Link to comment Share on other sites More sharing options...
A440 Posted October 14, 2005 Report Share Posted October 14, 2005 48 kbps is a regular MD format.Do it yourself: Put a CD in your CD drive. Open Sonic Stage. Tools/Convert Format. Under OpenMG AtRAC3plus choose 48kbps. (While you're at it, uncheck the copy protection.) You can convert the same track at any bitrate you want for comparisons.

greenmachine Posted October 14, 2005 Report Share Posted October 14, 2005 Looks like you need to install sonicstage first. Quote Link to comment Share on other sites More sharing options...
A440 Posted October 14, 2005 Report Share Posted October 14, 2005 Looks like you need to install sonicstage first.Which raises the question of how he played the 66kbps.... Quote Link to comment Share on other sites More sharing options...
RobA Posted October 14, 2005 Author Report Share Posted October 14, 2005 Which raises the question of how he played the 66kbps....I downloaded the 66kbps file from the MD faq here on minidisc.org. Quote Link to comment Share on other sites More sharing options...

RobA Posted October 14, 2005 Author Report Share Posted October 14, 2005 (edited) So many FAQs....what's the file extension?wav, but it wouldn't run until I downloaded a plugin from the faq entry Edited October 14, 2005 by RobA Quote Link to comment Share on other sites More sharing options...
A440 Posted October 14, 2005 Report Share Posted October 14, 2005 OK, here it is as a .wav (converted through Marcnet's invaluable Hi-MDRenderer). .wav is uncompressed, so it's a big sample for 24 seconds of music. What are you playing music through? Windows Media Player? Winamp? Real Player? iTunes? Any of them should have already been able to play .wav without a plugin. And how are you listening? Headphones plugged into your computer? Standard computer soundcards are not known for high-fidelity reproduction and headphones can be great or not so great. What you may be hearing in any sample is the limitations of your soundcard or your headphones. Generally, the bitrate is not the only thing that matters. mp3 at 128 kbps sounds different from wma at 128 kpbs or ATRAC (.oma) at 128 (well, 132) kpbs because each codec compresses different sounds in different ways. Lower bitrate means lower quality within each codec, but codec designers try to leave out whatever they think you don't need to hear, so some codecs may strike your ear as more musical than others. The question you're trying to answer is not whether music at 66 or 48 kbps sounds good, but whether ATRAC at 66 kbps or 48 kbps sounds good. By the way, can you copy the link to the FAQ?La_Grange_48.wav Quote Link to comment Share on other sites More sharing options...
Alexx Posted October 14, 2005 Report Share Posted October 14, 2005 IMO 66ATRAC is better than 105.how can 105 be SO poor? Quote Link to comment Share on other sites More sharing options...

The Low Volta Posted October 14, 2005 Report Share Posted October 14, 2005 ^^^that link is pretty old... as you're interested in knowing about atrac(3+) bitrate's SQ and you have already ordered the NH600 (I believe), why not just install SS3.2 from the downloads section and you can compare all available bitrates (read the manual from the NH600 or from any other first gen 'NH' HiMD model to see which bitrates are compatible with the NH600) and use some difficult/complex music you love and some good gear (preferably the phones you will use with the NH600) to test it for yourself...no use in using only this old and awkward test material, especially when you got to install the SS software anyway Quote Link to comment Share on other sites More sharing options...

I'm ordering it on Sunday. Quote Link to comment Share on other sites More sharing options...
bmanalansan Posted October 15, 2005 Report Share Posted October 15, 2005 Can you play this one?[attachmentid=928]Interesting to note: I can play this oma file and when checking for properties, it is showing that I can create CDs, ATRAC CDs and import it to a Hi-MD. I guess the "restrictions" associated with .oma file not too long ago are now gone when creating oma files with no DRM. Quote Link to comment Share on other sites More sharing options...
The Low Volta Posted October 15, 2005 Report Share Posted October 15, 2005 I'll check it out when I recieve the 600D. I'm ordering it on Sunday.good, but really no need to wait, the software bundled with the NH600D is SS2.0 so you should install 3.2 anyway... you could do it right now so you have something to have fun with until the NH600D arrivesas for the manual, just follow this link or download it at the minidisc.org equipment browserBTW: the NH600D can play the same formats as my NH900 so- PCM- atrac3+ @ 265/64/48- atrac3 @ 132/105/66(- atrac @ 292 = SP but as the NH600D is a downloader only you can't use it to create real SP, so not really useful)have fun Quote Link to comment Share on other sites More sharing options...
