In this week's session, we demonstrate how to align and mix boom and lavalier microphones using Sound Radix Auto Align Post 2. When you record with both boom and lavalier microphones, the two are usually not perfectly in phase so you experience comb filtering. Add plant mics and moving actors and the problems become even more pronounced. Auto Align Post solves this problem so you can mix them all.
Then we answer your sound for video questions.
If you’d like to learn how to make great dialogue audio for your film and video projects, please have a look at my courses at school.learnlightandsound.com including processing dialogue audio in Adobe Audition and DaVinci Resolve/Fairlight, recording sound, how to use the Zoom F4, F6, F8, and F8n, and how to get the most from the Sound Devices MixPre series of recorders. We have a course on sound for live-streaming with the ATEM Mini and just added Introduction to Izotope RX for Dialogue Audio.
