mp3 quality

Aug 23, 2007 at 2:21 AM Post #2 of 138
If I have to use mp3 I use 320, though I have some files at 256 (I think?) that still sound ok. Generally though I use FLAC, which thankfully the X5 can handle.

192 already has very audible artifacts, and anything below sounds very poor.

if you rip something from a cd you can't exceed CD quality. I honestly hear no difference between 320 and CD......also there'd be no reason to rip your music at 48Khz unless you were using a source that was 48Khz.......CDs are 44.1Khz.

On a second note, I'm heavily convinced that unless you analyze your music under a "microscrope", even with the best portable system (RWA iMod - hornet - UE11 / UE10) you will NOT hear a difference between a Wav file and a file encoded at 192 variable bit rate. I've tested 6 people and not one of them can tell the difference, including myself. There is not an audible diffence using the iMod, a corda move, a cotton dock and HD650s or K701.

In a time of luxury where science has managed to create brilliant sound while reducing space, I see no reason to over compensate as it were.......test and see if you can tell the difference between 192 vbr and a wav file. If you do, you are both very gifted and very cursed.

EDIT: I use AAC files NOT mp3 and because of this...you may want to try 224 kbps MP3 vbr instead of 192 because they tend to not sound as good as AAC at the same bit rate, however if you are using LAME to rip them, you should be okay with 192.

Don't convert your mp3s to anything. When you convert from a lossy format (mp3) to another lossy format you really degrade the quality. You may have to rerip your CDs. What are they ripped at right now?

I once converted my 320 kbps files to 128 just to see what would happen and amazingly, they sounded so bad that I compared it to 64 kbps and they sounded about equal. If you're looking to conserve battery life and hard drive space you have re encode your music, not convert the pre-existing mp3s. Which IEMs are you using and what portable player?

i personally use lossless format most of the time,basically because my portable source is a 80gb ipod so ive got the space to waste and the only reason i use lossless is because i dont buy expensive earphones and not get the best out of them its a must to get what i can from them,my current most used iem's are se530 if i ever use anything but lossless it is either 320kb bitrate or 256vbr

im using a sony psp and cx300-b iem's from sennhesier


thats not the best start sony psp isnt the best source really and the cx300 are not really high end enough to show seriously bad recordings so anything above 192kb bitrate should be sufficient but if its a must then 320 is the best quality mp3 format,and maybe vbr

192 vbr will be perfectly fine.......let me know if you hear a difference between 192 vbr and 320......make sure the vbr is on. Remember not to convert, but to rerip your cds


ye re ripping cd's is important to get the best result
