Whenever you need an Audio Editor to do: Audio Restoration - Noise Reduction - Undesired Pops/clips/Uhms/Empty Spaces/Mistaken Words Removal - Equalization - Compression - Levels Matching - Synchronizing Background Music - Add Sound FX - Mix and Master - etc... I carefully read what your requests are before sending my proposal, and my goal is, to fulfill them accurately and completely. I don't mind editing my work until I get it exactly right, the way the client wants it.
