Ficheiros MP3 - programa para nivelar o som ?

[Automek]

Conhecem algum programa, preferencialmente freeware, que permita 'nivelar' o som de vários ficheiros MP3 ?
Tenho aqui umas quantas dezenas de músicas, de diferentes fontes, mas a diferença de som entre elas faz com que não as consiga tocar sem andar sempre a aumentar e a diminuir o som, o que é pouco prático.

Acontece-me o mesmo com alguns podcasts que converti para MP3.

Tenta isto (faz parte das opções do sistema operativo)

Ah, esqueci-me do detalhe mais importante. Era para nivelar o som dos ficheiros antes de os passar para o leitor de MP3 (e não no PC). Enquanto corro é chato ter aquilo com diferentes tons.

Do you believe in magic? You will after using The Levelator® to enhance your podcast. And you'll be amazed that it's free, now even for commercial use.

So what is The Levelator®? It's software that runs on Windows, OS X (universal binary), or Linux (Ubuntu) that adjusts the audio levels within your podcast or other audio file for variations from one speaker to the next, for example. It's not a compressor, normalizer or limiter although it contains all three. It's much more than those tools, and it's much simpler to use. The UI is dirt-simple: Drag-and-drop any WAV or AIFF file onto The Leveler's application window, and a few moments later you'll find a new version which just sounds better.

Have you ever recorded an interview in which you and your guest ended up at different volumes? How about a panel discussion where some people were close to microphones and others were not? These are the problems the post-production engineers of Team ITC here at The Conversations Network solve every day, and it used to take them hours of painstaking work with expensive and complex tools like SoundTrack Pro, Audacity, Sound Forge or Audition to solve them. Now it takes mere seconds. Seriously. The Levelator® is unlike any other audio tool you've ever seen, heard or used. It's magic. And it's free.
