Couple questions about the Cowon D2

post #1 of 9
Thread Starter 
One question I have is, if you convert .wma's and mp3's to OGG or FLAC do they keep the compression? Or do I have to rip my music straight into OGG or FLAC? About video, I tried to convert some video to put onto my D2 and it wouldn't recognize it and I am not sure what to do. I am taking the video from a DVD so the video's are in .vob format. What can I do about this? I had this same problem with my SanDisk Sansa E260R, thanks in advance for any help.

Well your first question isn't that clear, so I'll assume you mean do they keep the same audio quality. Well FLAC is lossless so the conversion should retain the original quality of your .wma/mp3 but .ogg is lossy so coverting from one lossy format to another will degrade audio quality further. Though I don't know why you would want to convert from wma/mp3 to ogg as D2 can play those already.

As to your second question I usually convert avi using GOM encoder, try googling it, it has a preset D2 setting that definitely works on the D2 but I don't know if it can convert from VOB directly, not really the right forum to ask...

Hope that helps

I was wanting to switch because I was wanting my music in a lossless audio format. But if it keeps the same audio quality, I will just rip the music into FLAC (which I can do with the cd that came with the D2), but I do have some music that I do not have the cd's for (I got the music from a friend) so I can't rip them. I will look into the GOM encoder.

For the converter/ripper that came with the D2 it has 9 different levels of compression for FLAC (0-9) and 0 is fastest and 9 is highest as it is labeled. What are the difference between the compression levels?

I asked this very question awhile ago: the answer is simple -time. Meaning encoding time.

The SQ is exactly the same. It's all lossless.

For videos to play properly, they have to be converted down to 320 x 240.

Also there is no point converting lossy to lossless as all you do is increase the file size and no SQ benefit as yes, it keeps the compression. You can only convert properly from a lossless source file.

If your mp3's are of a low bit rate or quality then converting them to ogg or FLAC will make no noticeable difference in quality. You put poop in you get poop out you have to rip straight from cd to ogg or FLAC to get the results you want other wise your just wasting space. Trust me I when through the same deal. Oh and about the videos use the avi converter or Nero then use the Jetaudio converting suit that usually worked for me.

P.S nice player i've been with mine for over a year and love D2 FTW

IF you want the best audio quality, you have to convert straight from your audio CD to FLAC to retain the sound you would hear from the audio CD. With a lossy file format like mp3 or wma (which is already compressed music and not at its best) there is no point to reconvert to another file format for further compression (ie more sound degredation).

Cool, I will probably get an AVI converter then and I will be re-ripping my cds then, so only about 150 of my 700 songs won't be in FLAC. Those are the ones I don't have cd's for, thanks again everyone for your help.
