Hello,
I am professional audio editor with over 20 years experience. I am a contracted editor by Tongues Translation Services LLC , and I have had the projects with the same problem as yours. (I can send you the reviews from another UK based wedding video editor, whom I edited the audio tracks.
Feel free to contact me and send me your audio raw file for a view. If it is edible, I will edit a short sample of your audio and send you for the quality check. If you like the quality, you will be sure that the whole file will be edited with the same algorithm, and will be of the same or better quality,
We can discuss the price again after ..
