Normalization made a mess of my collection
« on: May 30, 2003, 05:06:08 am »

I re-encoded my entire collection of mp3's with the normalization option set at 90%.  Now I find that most of my songs abruptly stop with about 10-15 seconds of 'no sound' at the end of the selection.  In other words, a song which was originally 3 minutes long, now plays for about 2:45 and has no sound for the last 15 seconds.  The song is still listed as being 3 minutes long.

Is there any way to fix this, or did I just hose about 1000 songs?

Thanks,
Rob

I use the setting MP3 Encoder, normal, 128 bits.  I used a normalization of 90 percent, I think.

It's really strange.  The songs just abruptly end, but the elapsed time keeps ticking for the last 10 seconds or so.

Any help is appreciated!!

It was done under 9.0.176 or maybe 1 revision earlier.

Upon further investigation, it seems that the 'normalization' effected the 'fade' at the end of the song.  The part that I thought was silence is actually part of the song, after the fade.  It just fades so low, that it cannot be heard unless you turn the volume way up.  

The fade is over exacturated.  I think the issue is that I need to run some process on these mp3 files to fix the issue.

Is there such a program?

well you can not recover from that without distorting the sound more.

Re-rip, and turn off the Normalization and see what happens.

King is right.

Anything you may do will only make things worse - and takes time.

Look like you have to take your cds from the shelve another time....

See it as the opportunity to rip them in the best way.

Ask here about anything you are not sure about.

Some very nice --well almost very nice- members of this forum will give you any tips you need

It's just discouraging having to re-rip everything.  Some of the files were obtained thru file sharing.

Well, if I have to do it, so be it.

What are the recommended settings to rip cd?  My main uses are to hear the music on the computer, on the iPod, and thru Tivo home networking.  What settings would you recommend for this?

Thanks,
Rob

Try --alt-preset standard. If you want a bit more headroom --alt-preset extreme. You should be more than satisfied with the former.

EDIT: You can speed up the process by ripping to uncompressed wave first, then convert to MP3 in batch mode. Instead of using normalization, try Replay Gain when done. It doesn't alter the files when played back through MC. However, it will not make a difference with your Ipod. For that, and use good judgement here, try MP3Gain. Google for where to find that.

If you like CBR vs VBR try this

--scale 1 --alt-preset cbr 256

The --scale 1 just makes certain that the PCM levels are not adjusted before MP3Gain gets to them.

And by all means stay away from normalization! I had to rip a few hundred CDs again because of that, a mistake I'll never repeat. And also in the future, if you're going to do anything to your collection, do what I do: Keep a full backup of EVERY SINGLE TRACK! Really, with harddisk prices as low as they are now there's no excuse for not doing it.  8)
