In many TV programmes, the director is speaking to the show host via an ear-piece that the host is wearing, and at many instances, what is being said through that ear-piece is more or less audible without any processing.
How can I selectively amplify this voice from the background (what software/manuals should I follow)?
Here's an example:in this video on times: 1:06, 1:12 and 1:18. There is a clear dictation of what is said by the host. I need to know if it is possible to clear out and amplify this signal.
Thanks in advance!
