Question Which voice amplification program?

[dariuszpindela]

What program can to make someone's recorded voice louder when that person's voice is damaged? When someone smokes a lot of cigarettes and drinks a lot of alcohol for many years, they have a voice without bass and I can hear them as if they were talking only with air. Simply turning the volume up with MP3Gain, for example, doesn't do much and after turning the volume up the volume is still very weak and there is a crackling sound (it always happens no matter sound what I use when the volume level is too high).
Do sound programs have a function for adding bass and normal tone to a weak and damaged voice to make it sound like the voice of a healthy person? It was this type of loudness that worked the most.

There are "equalizers" that would allow you to boost or cut certain frequency bands which would certainly alter the sound of anyone's voice.

You'd have to experiment with them to decide if they are adequate for your purposes.

Audacity is probably the best known free recorder/playback program. It has a lot of functions, but it has a learning curve.

A simple equalizer may work for you. Or not.

Are you trying to permanently alter existing recordings?

Or are you merely trying to alter the way they sound during playback, as you might with a tone control when playing a phonograph record?

Second that. Even with a learning curve, that software IS free and Open source, so there are no "15 days trial period" or similar annoyances. One can feel free to test out each and every filter in that program until get somewhat better result.
