In this episode we talk about how 32-bit float audio recording works. In the past, I’ve referred to it as “wide dynamic range” recording, but that’s not entirely accurate. We’ll also talk about the ONE problem that 32-bit float sound recording solves, and many of the other recording problems and challenges it DOES NOT solve. And all of this is to make you a better sound recordist for your video and podcast and livestream projects.
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. Our latest courses cover Sound for Live Streaming with the ATEM Mini and an Intro to Izotope RX. See https://school.learnlightandsound.com for more info!
