Properly Mixing Phone Call Audio

Sometimes it can be tricky to mix phone call audio (usually the guest) with regular microphone audio (usually the host).

The reason is because the phone call audio has a severely reduced frequency range. For more information see the three Daily Goody’s that I have linked to at the bottom.

In my experience, most folks set the phone call audio at too low of a volume. And if you ever listen to a radio station take phone calls you will hear that the phone callers actually sound a bit LOUDER than the host! And this is actually a good thing because phone audio is significantly more difficult to understand because of it’s diminished intelligibility.

Also, most folks don’t EQ the phone call audio to have more clarity than it normally does. Normally phone call audio is not very crisp or clear, and a bit of EQ’ing can make a huge difference in intelligibility. (Maybe remove some mud around 250-450 Hz, and/or add some clarity by boosting around 2-3 kHz)
