As Volker said, I think normalize will do the trick. It can normalize |
| 12 |
a batch of sound files so their volume level is the same. I would, |
| 13 |
however, suggest you decompress the MP3 into a lossless file, that way |
| 14 |
you aren't re-encoding and reducing sound quality further. |

Also, your video editing software may be able to adjust the volume of |
| 17 |
the individual audio tracks. Kdenlive, for example, has a normalize |
| 18 |
audio track filter. |
