I will solve all these problems and master your audio to get a high fidelity (HI FI) audio file, and you can burn it on a cd.
I can also mix two audio files with each other one file for narration and the other for background.
The audio mastered file will be in Wav format
I will make a trial for 5 seconds for free, this is worthy to try it
Moreover, if you have a video with a noisy audio, I'm going to solve this problem too, just send me your noisy video and get it back with a high quality audio, but this requires extra GIG.
I do NOT introduce this service for pornographic videos and audios.
