What is the voice amplification program you are referring to?
There are tools that let you adjust specific frequency ranges, which can significantly change the tone of a voice. You'd need to try them out to see if they suit your needs. Audacity is the most recognized free recording and playback software, though it has a steep learning curve. A basic equalizer might help, but its effectiveness depends on your goals. Are you aiming to permanently change existing files or just modify their sound during playback, similar to adjusting a phonograph?
Additionally, despite the learning curve, this software is free and open source, eliminating issues like a "15-day trial period." Users can freely experiment with each filter until achieving the desired results.
