Hello, I have been doing audio work & running a recording studio since 2014. My studio has all the modern tools (RX etc) & I know more than a few tricks & techniques for audio restoration. I understand the goal is to make dialogue intelligible - not make sound polished. (Please note that if the recording is completely toast, there is no amount of enhancement that can reveal a whispered conversation that was 10 metres from the microphone & took near a freeway) I will do my very best for you regards Derek

I have actually done this exact task before, when recording an employer who was acting in a way that wasn't legal. I recorded the audio on my phone, in my pocket. I then took it home, used manual editing to remove pocket fabric noise, used compression to normalise the audio volume, and used parametric eq dipping to reduce static background noises. The audio was accepted as proof by the parties concerned. i can do this task for you quickly and efficiently. Thanks for your consideration, I hope to work with you on this.

I will work on the audio file and clean it up perfectly going with the most detailed work i can manually if it is necessary, I think it will be. cleaning the background noise and using the correct tools for each of the voices if it is necessary. First I will enhance the audio with all the noise for the cleaning process to take place better and find the voices and do not cut them, then I will work on the voices individually if there are various, and will try to maintain the same volumen for each one. Using the correct compressor for make it more understandable.
