Hi,
I can do this easily for you, I'm a musician 15+ years and an expert user of Ableton live, with which I compose, arrange and mix. I have experience editing audio files to remove noises, hisses and any other interferences to make them sound crystal clear and clean. I'll do this for you and I'm very quick.
I'm new to freelancer but I assure you I'm a gem to work with.
Thanks!
