Camera Menu Settings for Audio

What are 3 separate thing that the presenter says to keep in mind when setting up your camera to record audio? Why are each of them important? What is one different thing that you would like to learn more about?

1. Audio Input- Internal Mic Low Cut

It is important to utilize this feature when shooting outside because it is helpful when cutting off wind noise. LC1 and LC2 identifies the intensity in which the audio is protected from the wind noise or any low frequency noise.

2. Audio Input- Internal Mic Sensitivity

This feature may be turned on when an external microphone is unavailable and important audio such as a dialog has to be captured. Although this inevitably increases noise, it can be a useful function under emergencies.

3. Audio Input- Mic/Internal Mic Attenuation

This function can soften or dampen the sound captured overall. This function is useful in loud situations such as a concert or potentially a documentary. However, it is important to keep in mind that  this function can only be used if the external microphone does not require phantom power.

I would like to learn more about how audio can be altered in post production.
