What would be the best way to record room ambience for ambience fx (not room tone for dialogue) with one mic? I'm limited on that side. Should i just transform mono to stereo later?
- Record one long shot.
- Split it from the half.
- Put one half to the right channel and the other to left channel.
- Export a stereo file.
This way you will get a very wide stereo image that is hard to get from a stereo field recording and your sounds in the front will be clearly distinct from ambience.
Do not just transform to stereo. If you do that, you will not get a stereo sound but only double the file size because right and left channel will contain the same information and playback will again result in a mono output.
