Hi! I am an audio engineering, and have been working for 7 years in audio edition, restoration, and normalization. As I am new on this site, I offer you to do half of the job for free. Lets say 1 minute of edition, so you can be sure of the quality of my work. If you like what you get, we can go on with te full proyect. If you like my offer, please send me the audio file.
