Audio Enhancement for Clarity & Volume

I require an expert in sound engineering or audio editing to perform voice enhancements on a batch of audio files. The current volume of these files is quite low and the clarity is insufficient, so I need someone who can effectively elevate the voices and eliminate any distortion. Key tasks: - Amplify voices for better audibility - Improve clarity of the dialogues - Remove distortion and unnecessary noise Ideal candidate should have: - Relevant experience in sound engineering or audio editing - Proven track record in voice enhancement and noise cancellation - Ability to work on large batches of files (more than 10) - Efficiency in handling tasks, as files are less than an hour each Please confirm your experience in this type of work and provide examples, if available, with your bid.
