MP3 High End Loss on Export?

[drutgat]

Has anyone had the experience of loosing a lot of the high end when exporting to MP3 with the Micro BR?

I've noticed it a couple of times, and wonder if it's something to do with the way the MBR compresses to MP3 (although it should be a standard algorithm, and I've never had this problem with going to MP3 from various computers).

Perhaps it's necessary to overcompensate by pre-mixing with more treble. I haven't tried this yet.

What do you all think?

I did notice the extra high-end loss, so I tend to export to wav and convert files in the computer.

i save at 192kbps and i think you need bat ears to hear the difference from that to wav. however my auld ears are getting a bit dodgy.

pardon.

Why must you always make fun of my ears?

Hi Blooby and OldRottenHead,
Thanks for the replies.

I had considered exporting to .WAV in the future, but when I want to send friends an MP3, it would seem an unnecessary step to do this first.

ORH, the MP3 bitrate to which I've exported, and at which I can clearly hear an absence of high end frequencies,  is 192Kbps.

Any ideas about why this happens?

when you are mastering, what mastering effect are you using that can have a major effect on how the song sounds.
or you just have great ears and im an old deefy.

I haven't noticed any loss of anything on exported .mp3's

In fact, the BR's mastering process seems to improve the sound balance on my stuff. I can just about tell the clarity between 128kbps and 192kbps, but WAV exports don't add a lot to my ears. But maybe my hearing's been frazzled by years of loud guitar in my lugholes....

Good question. You know, I didn't make any alterations to the mastering effects; I guess that's my point - I was using the 'default' settings. But, I guess I made an assumption that the mastering was set 'flat', i.e. with everything at 'zero'; maybe that assumption is incorrect. I will look and get back to you tomorrow.

Can't believe I didn't even check this.

Greeny,
I don't have great ears when it comes to playing music, but I have always found it easy to notice relative differences in mp3's up to 256 kbps (is that the one above 192?). The top/high end suffers, as does the bass.

I also find that the codec (right word?) used makes a difference; although I have made over 30 GB's of mp3's now for use on my player, I use CDex, mainly out of convenience, and find that it's not the best encoder. Used to use Exact Audio Copy, but it would always screw up. Maybe I'm being ignorant about things here, but I've found that the same song, played on the same equipment, made with different codecs at the same bitrate can vary quite a lot in quality.
