This is a great PSA. I am a 13 year IATSE sound mixer and work on the highest budget biggest shows you can think of. I prefer to record in 32 bit when possible, giving myself a safety net on these type of do or die shows to avoid ADR, especially when dealing with actors who are super dynamic in their performances. However, I always check with post and will often offer to batch mod for dailies when passing off the sound roll when editors are working on AVID systems. This technology becomes particularly handy when you have actors in a scene going from a soft conversation or whisper to a fight or shouting match.

I personally don't know anyone who is interested in 32bit float for high gain clipping. For Events, Weddings and Funerals, I find it much more useful for bringing up the "quiet one", or the "crying one", without bringing up the noise floor. There's always the one who is afraid of the mic, or holding it in a way where they are difficult to hear. That is what excites me and those I've talked to about it. A lot of us have two channel recordings with one hot and one not to keep from the clipping disaster.
@tomdchi122 жыл бұрын
To further complicate things: It's important to keep in mind that "high dynamic range" audio capture is two parts: Yes, 32 bit float avoids the file format from limiting what can be captured, but you also need equipment that has multiple analog to digital converters (ADCs) staged to capture different loudness ranges like the Mix-Pre II units. A good, real-world ADC can't handle much more than 120dB of dynamic rage - which is a lot, but wether the source has a lot of range like a race car, or you aren't as skilled as Alex and you just didn't set the levels well (or didn't monitor them because you're a solo shooter), you can risk clipping. A product like the Rode Wireless Go 2 can output 32 bit float, but because it only has one stage of ADC, it can never record that wide dynamic range without either clipping at the high end or losing the signal in the noise floor at the low end. Converting a limited signal to the "larger range" of a 32 bit float format won't improve what was actually recorded.

If they set up the chain correctly, then 32-bit float is a no-brainer.

I do take issue with the recommendation to throw away the 32-bit float files after the fact. They're only 33% larger than their 24-bit counterparts. The benefit of keeping them is that when the rest of the production chain finally catches up, you may be able to reap the benefits of that in remastering or reuse in a future project. Or, you may decide to mix something differently. Who knows what tools, techniques or capabilities the future may hold? I always keep my RAW files for photography, and as new RAW converters have come out, I've been able to reprocess old images in a way that makes them look so much better.

the 32 bit float recording on the Sound Devices Mixer 3 ii is what allowed me to finally purchase a field recorder that wouldn't give me anxiety for recording my choir concerts. I'm fairly savvy on the photography/videography side of things, and my whole world has been music since I was a child, but the specific area of what audio capture device I need to record something like a concert was brand new to me. On top of that, I have ADHD. I'm a one man band who decided that I wanted to have good recordings of the concerts I participate in for when I want to remember these moments. Finding somebody who happened to be recording on a phone that manages to have the right audio is incredibly it or miss, and whether or not they upload the whole concert, just a part, or nothing at all, means that's not a reliable way to capture these memories. So I buy all of this equipment, and I personally set it up on the day of the concert, during whatever time exists between dress rehearsal and the moment of performance. The ADHD paralyzes me enough, with the fear of forgetting something important, or leaving something behind, or not having the correct gain settings, etc. I can deal with messed up video. I'd probably give up if I experience an amazing performance and some mistake I made messed up the audio I worked so hard to try to get. 32 bit means that I don't have to worry about that at all. It doesn't matter how loud or soft the music may be, how far away I've set it up, or if there were elements to the performance that I couldn't account for because they weren't addressed during the rehearsal. As long as I have set up and powered my recorder, the audio will be captured, and I can spend whatever time I need in post to bring it to where I need it to be. Now that I know better, I could probably work with 24 bit audio without being afraid I'll do something wrong, but 32 bit is what allowed me to have the peace of mind that, no matter what, I *will* capture the audio as long as I make sure that a small handful of things are taken care of, and is what allowed me to start recording my concerts with enough confidence to learn as I go.

(3.40282347E38 if you want to be precise) It's an entirely different kind of number! Very wierd, but very useful for dynamic range. You absolutely CAN clip with 32 bit PCM, you absolutely CAN'T clip with 32 bit float - it's functionally infinite, as you can see. An over-simplified way to think about it is floating point numbers aren't one number, they're two numbers: a base, and an exponent. 2 to the power of 4, for instance, 2 and 4. That exponent allows the ENORMOUS range. If you want to dive into the maths, wikipedia is pretty good: en.wikipedia.org/wiki/Single-precision_floating-point_format I agree with your conclusions, however - once the dynamic range is normalised, save in your normal formats (you could use 24bit non float to usefully keep the bit depth, while maintaining compatibility with video editors, I believe) I edit my videos in Reaper, so I have no problem XD

32 bit float is always worth recording in even if it gets downgraded later. The file size is not a problem considering professional cameras record a terabyte of footage every few minutes and there are so many bad directors who can’t seem to understand this and say cut. DAWs will eventually get upgraded to support this format if they haven’t already. There’s always going to be a limiting factor that prevents new technology from working most effectively but that shouldn’t stop you from investing for the future. Yeah if you have a Zoom F6 or any cheap device like that with 32bit float you most likely don’t know what you are doing and are using it as more of a safety. Professionals can more accurately gain stage, but every now and then theres still some guy in post that says it’s not loud enough or quiet enough so 32 bit float is a good way to solve this problem.

The bit depht is not so much about accuracy nor how weak and strong sound we can record. In the end it sets the noise floor at a defined level. If no other noise are there to do the job we apply dither noise. With dither all acuracy and such disapears and instead we are left with a perfect signal that is getting masked by the noise floor that the number of bits define. Noise is a good trade for a practically perfect signal. We hear noise as a separate sound and if we let our music fade out and we raise the volume to hear these weak sounds, the music get lower and lower and finally is perfectly masked by the noise floor. So in practise it is a fixed noise floor that is defined from the number of bits used. If no noise is used to dither the signal when such is needed, you are doing it wrong and the quantisation distortion and the limited low amplitude handling becomes real. So use dither and get rid of those problem! Dither is part of the PCM coding for audio signals. The other limitation is the sampling frequensy that sets the upper limit for frequensys that can be recorded. So PCM is limited by a noise floor and a limit for how high frequensys we can record! Pretty simple. But this is the ideal system were hardware limitations does not exist. In a real world set up. Hardware are not perfect!

"32-bit recordings are going to be much, much larger in size than their 24-bit counterpart"? A 32-bit sample file require exactly 33% more storage than a 24-bit sample file. That's 4 bytes per sample versus 3. Pretty simple math.

I don't agree that it causes issues on the picture editing side. They are still just Wav files, 32bit doesn't have some special codec. My experience is that video editors aren't even aware they are 32bit float and they will import into a video editor just fine. The problems arise when we get projects back from the editors, they inadvertently convert the 32bit files to 24bit and clip all the loud audio. Meaning when we get it back the audio files are destructively clipped. The problem is video editors don't understand 32bit and not bothering to look it up as they just think it's an audio issue. The solution is for video editors to keep the 32bit pipeline open. But they always bottle neck it.

I understand perfectly what do you mean. I’m not an audio professional, I do video and photography a a solo shooter. Anyway, I see this like RAW video or photos, there is room to play with but is not magical. I teach photography and media production and I always tell my students that the image need to come out of the camera as best as they can. Having the ability to record 32bit float is great, but resting in the idea that you will be able to recover anything is false. I have Rode Mic Pro and I did few test and there is point where you can’t up the audio. So, if you take care of the audio during recording, it will be less work in post saving you a lot of money! 🤷🏻♂️

DAWs like Cubase process 32-bit natively. It's been like that for years now, so using 32-bit in post shouldn't be an issue. I think the problem focuses more on the knowledge gap that exist between people working on audio and the people working on video editing. Closer collaboration between video editors and audio mixers, and knowledge about each other's workflows, would certainly make the production flow faster and better. If you are a video editor, think, Is this audio file on my desk, perhaps in 32-bit? And, if you are an audio mixer, think, Should I dump a bunch of 32-bit files on the editor's desk when no editing software is capable of handling those files?

Excellent discussion to help creators with a bigger picture well outside of their domain. This covers a basic concept I learned back in the day when one had to be a chemistry major to be a photographer if I wanted to control my content. Put in the effort to master how to pick your tools and resources that are capable of the most tricks without getting in the way of the task at hand. Then capture the maximum range of data with the best accuracy and precision possible so you have a much wider range of control of editing in the darkroom ... I meant the editing software. The more things change the more they stay the same. Learn the absolute limits of your tools and master using them with fast, efficient precision and accuracy. I do not miss the era of 13 steps of chemistry controlled with extreme purity and temperature control to find out what I captured.

Great PSA Alex. Lately, my first technical question for sound gigs has been to contact the post or editing folks if 32-bit works with their rig. Always communicate what you're going to do. This might seem obvious for some but another PSA is that wireless Rx and Tx currently don't transmit in 32-bit so there's not much point if you're only recording with wireless lavs.
@BrewReview11 ай бұрын
Pro level wireless transmitters and receivers are typically analog. They don't HAVE a bit depth. In this situation, if you clip on the way in at the Tx source it won't matter what happens down the line at the recorder, it'll still be clipped. But since the analog signal goes through a DAC at the recorder, 32bit would still matter upon conversion assuming the signal from TX to rx is not clipped.

32fp mode should be used ONLY if sudden very loud events are predictable. The mic preamplifier has no infinite dynamic range thus, there's a tradeoff between analogue headroom above 0dBfs and S/N ratio at lower levels. The larger allowed peaks over 0, the noisier audio at lower levels. To deal with sudden loud sounds, i still prefer to use an Y cable to feed, if available, 2 channels at 24bits with different gain settings. One set to deal with normal levels plus one 20dB lower, just in case the first channel goes over.

I'm glad this didn't discourage me from using 32-bit, I sill see it's value, but you've reminded me to think about it critically and logically. There's a creative application- for recording that extra dynamic range, but you have convinced me that it's not an essential evolution. It's just another tool in the box. I mean, you have to edit sound and picture anyway to get it to it's finished stage, and as others have mentioned, it's like applying a grade to a RAW video. Just a little extra post processing. But there is no point in doing it unnecessarily. It's easier not having to worry about setting the gain, but every creative or technical decision is better when it's properly considered and done for a reason! Set and remember! Thank you, Alex!

I am confused about one thing: more bit depth is presented as "more dynamic range", ie you can accomodate signals with more extreme variation in amplitude. But it is also presented as "more resolution", ie the same signal will be represented better and with more detail. So, if we take this to a graphic representation of amplitude vs time, in the first case you have higher Y axis maximum values, and in the second case you have the same maximum value, but with a tighter grid. I am probably missing something, but how can the same concept (bit depth) represent these two different situations?

It isn't that difficult, especially for predictable situations like voice over. On the recorders which record in 32-bit float with multiple converters per input AND have gain control, where you set the gain CHANGES the quality of the sound you end up recording.

Check with post, in my experience by now everyone is capable of ingesting 32-bit PolyWAV audio. I'd rather risk going above 0 in 32-bit than hitting the limiter (granted the analog limiters on our pro gear have been incredible for years now - but still, i'd prefer the uncompressed audio). Proper gainstaging still applies, things can still clip at the mic, at the transmitter, and at the receiver. Size is no issue, sound is still so small next to what DITs / data managers deal with for camera.

No. Not too technical, even for me. However, it doesn't seem like an argument against recording in 32 bit. Rather, it sounds like a very good argument for suggesting that those 32 bit recordings should have levels set in post and then reduced to 24 bit before being passed on. It's a bit like a photographer shooting RAW. You wouldn't supply RAW files to the client or graphic designer, but convert them to full colour.

But if I'm recording a rain forest where I need to capture everything from the raindrops to lightning, or a wedding where I need to capture people whispering, giggling and people shouting, I like having 32 bit float. Also the size differential is inconsequential (it's not a deterrent) and I'd much rather have the power of having 32 bit float recording. Honestly the moment I began using the Zoom F6 I can't turn back, it's a game changer - it has increased my workflow and speed because it's practically impossible to mess up a recording with 32 bit float.

This is a bizarre criticism of 32 bit. Particularly that Avid and Protools has problems with it. They have problems with Log3 too, so are you not going to use wide range original recording to accommodate Digidesign? The professional attitude is that if you screw up the sound, you don't work again. As for space and processing power, it's a joke today. If there is no quality issue, then the choice is a no-brainer. Clipping is only one issue among many. 32bit also gives you a much greater ability to compress sound in post into the "Zone" without artifacts and overcooking the sound.
