I am using Winamp 5 as my Mp3 jukebox on my Pc. Is there any way of making all of my Mp3's the same volume as some are loud and some are quiet.

Its getting a bit annoying having to mess about with the volume after every tune.

The straight forward way?

Convert MP3 --> WAV
Normalise WAV
Convert WAV --> MP3

dbPoweramp should let you convert MP3 --> MP3 with normalisation.

Will this method not reduce the quality?

Theoretically, but there's no other way to change the actual volume of an MP3 file.

You may be able to find a player that will 'smart normalise' your MP3s on the fly.

Loss of quality wouldn't be an issue for me. If it was, I wouldn't be using MP3 at all.

There are plenty of tools that will play around with your mp3s, but I would have thought they would all decrease the quality. Why not try a winamp plugin, since that's what you use to play them?

Example: http://www.winamp.com/plugins/details.php?id=145565 (haven't tried it, that was just the first one I noticed that sounded suitable)

If you have 2 PCs, you could take the audio out of PC1 to the Line In on PC2, play audio on PC1 and record as a Wave file on PC2.

You can then convert the WAVs on PC2 to MP3 whith the minimum ammount of quality loss.

(This can also be achieved using 1 PC providing your sound card support simultaneous playing & recording - and your PC is up to the task).

It's long-winded, but works pretty well;).

Umm, if you're going to transcode, why not just convert them all to wav digitally? :) I'm not sure adding a D/A and subsequent A/D conversion is going to help matters!

It is when you encode in MP3 that the deterioration occurs, try other compressed formats such as OGG and the quality will not (but still will) be as bad.
Before you ask, WMP doesn't support coz it's lame, and Winamp 2 upwards supports it.

To encode in OGG with dbAMP, just download the extra codecs, OGG will then appear in the available encodable formats.

whatever you do DONT transcode

its as simple as that, transcoding music drops the quality horribly, as different codecs use different algerithms

IIRC MP3 is uniform, so essentially, if youre ocnverting to wav then mp3 your file quality will drop by a square? argh I am too tired to work it out

Media Player 10 has an "auto volume leveling" facility that doesn't affect the sound quality.

From what I can tell it works out the average volume level of the track and stores that information as a custom ID3 TAG. When it plays the file back it adjusts the volume acordingly.

Works for me :)

Just been looking @ what I've got installed on this PC & I found mp3DirectCut (http://user.uni-frankfurt.de/~pesch/) which is a small freeware utility that allows many kinds of mp3 manipulation (volume adjustment is just one of many).8)

Been using that for a few years too. Not to manipulate volume levels but to edit radio recordings.

Me too:thumbsup:.

I'd totally forgotten about it till this morning (manually "Spring Cleaning" my HD).
