Sound for Video Session — Impedance & Q&A

In this week's session, we cover the basics of impedance (a specification you will often see for microphones, preamplifiers, audio interfaces, mixers, etc.) and 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 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.

Sound for Video Session: What are Impedance and THD and Other Specs?

In this week's sound for video session, I talk through a couple of the specifications you often see listed for microphones, preamps, recorders and such: Impedance & Total Harmonic Distortion. We also talk about impedance bridging and what this means when choosing a microphone, recorder, mixer, or preamp.
