THANK YOU ALL FOR YOUR SAMPLES. I have hired someone now.
The audio quality of this 38 second clip is really poor. It is too quiet, there is background noise and hum and the primary audio has some echo/reverb. I have attached an 8 second portion. Whoever sends me the best fixed version of the 8 second segment, I will award that person the job for the cleanup of the whole 38 seconds. This audio is for a video and it needs to sound as pro as possible... not just louder but better, richer. And please do not alter the timing, bit depth or sample rate.
