clean up a phone interview recording

I have a phone interview recording we did recently. The voice of the person being interviewed is very low due to the phone line connection; there are some slight crackles at one point of the interview that need to be cleaned up as well. We would like all the voices to be made equal volume and the back ground noise smoothed out a bit where needed. The recording is 20 minutes long and saved as a WAV file. Job would suit someone who is an audio engineer or who has experience in the audio area. We would like the recording changed to MP3 format also. Also as we would like the recording to play as a normal CD, e,g be able to play on a car CD player or portable CD player etc. We would like the job done within 7 days of accepting the job. This is only one of a lot of other work we will need in this area very soon. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
