Problems with headphones/music/itunes/gear/ who knows?

post #1 of 10
Thread Starter 

While trying to find out how much difference I could tell between music bitrates, I've come across a problem.  In particular, with the song "layla," I have a version that I got online which bitrate is 128 kbps, and I have the CD which I imported to my computer and put them as apple lossless files.  However, the lossless version has this nasty background hiss which worsens at certain times with the vocals and they almost bleed together.  The 128 kbps version sounds almost infinitely better than the lossless version in this case.  I've also noticed the same pretty annoying hissing sound on the other CD's I've imported using the lossless encoder.  However, the hissing is relatively constant and doesn't change much between frequencies. I'm using Soundmagic hp100 headphones.  I'm wondering why this is?  I notice this both on my ipod when it plays and when it's coming straight from my computer.  One other thing, a CD which I imported at 320 kbps has no hiss in it whatsoever.  I can't tell a difference between 320 kbps and lossless anyways besides the hissing, but why is the lossless version so much worse with this and if possible how can I fix this?  Would an amp help to solve this? I ordered a fiio e11 a few days ago which is on the way, not for this reason though.  Any help is greatly appreciated.

Could be something wrong with iTunes.

 

Try re-ripping an album or two using ExactAudioCopy (EAC).  There are guides and instructions around the web on how to get bit-exact rips via EAC.  Rip the tracks to WAV then use any program (except iTunes) to convert the WAV files to MP3 or have iTunes convert them to Apple lossless.

 

If you still get hiss, just re-rip your albums into MP3.

 

Amplifiers are irrelevant to this sort of issue.

Thanks for the quick response, I'll give that a try.

re-ripping an album to mp3 didn't change the hissing sound at all.  I don't have any issues with albums downloaded from itunes, just from albums where I have imported from the CD.  It's gotta be a computer hardware issue or something.  But, it also has the same hiss on my ipod.  If that's the case should it also have the same problem coming from my ipod if i synced it from my computer?

Did you try ripping a CD to .wav with EAC just to see of there is a difference?

It's called tape hiss. It's from the playback of the analog tape used during mastering. I have the 80s 2 CD version of Layla and it is very hissy. Most audiophiles prefer to hear tape hiss because it means that it hasn't been subjected to noise reduction. When removing hiss other details get removed in the process.

The hissy version mastered by Dennis Drake is considered to be the best available version of Layla by many. I prefer it to the the SACD which I also have. Chances are the 128 mp3 is from a different mastering than the CD you have.

I completely understand what you're saying with certain tracks.  But as I said in the original post, layla in particular, there's clearly a problem with something considering the vocals add a hissing sound and get very distorted at certain frequencies.

No i haven't tried that yet.  I downloaded the program yesterday though.

Do you have the 1995 remaster? This thread from another forum reports the same thing.

No, it's from the "Complete Clapton" disc 1.  It was made in 2007.
