Thanks Hans, I supposed the same that you tell me about lame includes aditional information. The problem is that I'm converting several small wav files into mp3 individual files, and then I concatenate all together in just one mp3 file. More files concatenated, more the total time error I have. I think that some method should exist to avoid this.
