audio editing

Project Description:
We have audio files that are audioguides to visit cities.

Those audio files are being recorded and we need someone :
-to process audio editing (remove breath...);
-add a music in the background.

We will send you samples to show our expectation on the final result.
We expect a flow of about 5 hours / months.

Please bid for audio mastering of a 1 hour audio file.

thanks
