Hi - I have a very small job. I have a 10 minute recording, initially recorded with an Iphone saved as an MOV file. The audio was too low so I increased the volume by 1500% using video convert software. This has left a very loud hissing background noise. It is now saved as an AVI file 948 MB. I figure that increasing the sound volume has distorted the audio somehow. Is it actually possible to get rid of the hissing sound?
I would be willing to pay a say $30 to get rid of the hissing sound.
