I need an mp3 guru

[manuchau]

Hi...relatively new to the world of burning music, although I've burned many software backup cd's successsfully. A friend is taking a yoga class, and needs a bunch of tunes to play back at different loudness for each tune.

I presume that most software will normalize sound levels. How can I record a cd with some songs at loud volume and some with soft volume without him having to get up and change the volume for each new song? What software is the best for this?
Thanks..

Hi Manu !

MP3Gain will be just fine for this job...

get it from there :

Hope this helps.

you can also try Sonic Foundry Acid Music Pro.
First, you must encode your digital Audio or MP3 to wave file.
You can then edit the wave file in the Acid Music Pro by changing the desired volume of that track.
Save as MP3!
p.s.
ds s my own style so u may cherry pick or do nothing.

mp3 loudness

Or you may use cakewalk, any of their sound editing versions will do. You'll have to work in .wav format, then encode back to mp3.

Avoid re-encoding a wav file back to mp3 before burning it to disc. Doing so will drastically degrade the sound quality.

Hi Grey, wouldn't that depend on the quality of the encoder you are using? and, obviously, on the quality of the originally encoded mp3?

Sure, the encoder does have an effect on the quality, but mp3s are 'lossy' compressions - meaning that file-size is reduced by removing digital information from the original wav file. Once its removed, it's gone for good and won't be restored when an mp3 is converted back to wav.

So, if you convert an mp3 to wav, and then convert that wav back to mp3, you're removing information twice.

My whole point here is this: Once you've normalized the wav file, use that wav to create the CD. Re-encoding isn't necessary in Manuchau's case, and doing so will degrade the sound quality. Why make it sound worse if you don't need to?

Use Nero Normalize Filter

Simply use Nero Normalize filter!

My problem solved with this filter, all my CD audio track
burned with the same level!.

For your problem, simply apply the normalize filter for each
track which you want.

Peace!

I recently started using Nero, but have never tried the filter. What's the problem with it?

Just curious.

my 2cents

I Think we were all a bit missled by the original post "need mp3 guru". Forr my part, I assumed he had mp3's on a cd that he needed to change the volume levels to and then put them back on a cd in mp3 format. Fully agree no need to re-encode to mp3 if the task at hand is not the one just described, as it would further take from the sound quality/fidelity.

My 2 cents on high quality digital sound manipulation: Cakewalk of Logic Audio Pro, and nothing like Cleaner 5 for encoding.
