32 Bit Floating Point Explained - Sound Speeds

Since the Zoom F6 was first showcased at NAB 2019, the world has been raving about 32 Bit Floating Point Recording. Truth be known, it's been around for years before that and has been used in post mastering for about as long. Understandably you want to record the best audio possible so shouldn't that include recording in 32 bit floating point? You may think bigger is better but it very well could make your life more difficult if you do. Not just because it means recording file sizes 1/3 larger but because it could bring with it more quantization errors and high noise floors. Should you record in 32 bit float? In this video I'll explain 32 Bit Floating Point so that you can make the determination for yourself.

Two mistakes... At 15:33 and 15:43 I said 192dB twice and I should have said 194dB. At 5:12 I say "1 volt of current". It's actually 1V of voltage. Current is a measurement of Amperage.
