In this week's Sound for Video Session, we cover 32-bit float audio, why I think that is a bad name for this technology, and when it is a valuable tool vs when it is not really necessary. Then we'll answer your sound for video related questions.
Sound Devices on 32-bit float audio:
32-bit float files explained — sounddevices.com/32-bit-float-files-explained
How is a 32-bit float file recorded? — sounddevices.com/how-is-a-32-bit-float-file-recorded

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.
