I have a audio file which belongs to a security camera that recorded inside of a cabin. There is a conversation taking place outside of the cabin and I need to get that conversation. Is there a way to do that? Removing background noise via Audacity didn't help much so far.
Use RX 5 Audio Editor.
You will probably get better results than with Audacity.
RX 5 allows you to recover certain parts that are missing.
Many quality presets are provided and you'll also find exhaustive documentation on the net.
