Canon5Dtips Photography is more than words.
If you use a Beachtek DXA-5D to capture sound while recording with your 5D, you should take a look at the new droplet my friend Mathieu has created. The droplet convert the file to ProRes HQ and remove the low frequency used to disable the audio gain. Simple, but effective.
If you would rather use other devices, take a look at this post on audio devices.
