What is 32-bit Float Audio?

Simply put, 32-bit float means your audio will never clip or be too quiet. Whether you're shouting at the top of your lungs or whispering softly, you can adjust the volume in post-production without any loss in quality. It's not just an auto-gain feature; it's far superior. Imagine having the flexibility of raw video, but for audio.

The Problem it Solves

We've all been there. You're filming an interview or a scene, and when you play it back, the audio is distorted because it's too loud, or it's barely audible. With 32-bit float, those days are over. No more nasty clipping audio that ruins your perfect shot. Even if you're recording in a quiet environment, when you amplify the sound in post, there won't be any added noise. Of course, the proximity of the microphone still matters for optimal sound quality, but the flexibility 32-bit float offers is unparalleled.

Why is it a Big Deal?

Audio quality can make or break a film. While visuals are crucial, poor audio can quickly distract and turn off viewers. Many filmmakers, especially those just starting, often struggle with audio levels. With 32-bit float, the need to constantly monitor and adjust gain levels is eliminated. This technology ensures that audio is consistently clear and at the right volume, regardless of the recording environment.

Any Downsides?

The only real downside at the moment is compatibility. Not all cameras or recorders can handle 32-bit float. So, while you can record in this format on specific devices, transferring that recording to a camera might mean losing the 32-bit float quality. This necessitates syncing files in post-production, which can be a bit of a hassle. However, as the technology becomes more widespread, it's likely that more devices will support it.

The Future of 32-bit Float

Given its advantages, it's easy to predict that 32-bit float will become the standard in the near future. It wouldn't be surprising if, by 2024, most cameras and audio recorders adopt this technology. The benefits far outweigh the current limitations, making it a must-have for filmmakers.


In the ever-evolving world of filmmaking, staying updated with the latest tech is crucial. The introduction of 32-bit float audio is a testament to how technology can simplify processes and enhance quality. It's not just about making things easier; it's about pushing the boundaries of what's possible. And in 2023, 32-bit float has done just that for audio in filmmaking.
