- Hey everybody, welcome back to another video.
In this one, we are talking about the magic
that is 32-bit float audio.
It is pure magic.
But first we're going to give a call out
to one of our craft beers here.
This is one of the original craft beers in Ontario, Canada,
Creemore Springs.
They've been around for a long time.
They're about 30 minutes from me.
This is their classic lager and it is a damn good beer.
I've been drinking this, it's been one of my favorites
since before I was legally supposed to have a favorite beer.
Okay, so let's go into it, 32-bit float audio,
what is it?
And how does it help you on your production
and the work that you're doing?
So I first saw some samples
of 32-bit float audio on YouTube.
Hearing people speak about it and talking about it
like it's the RAW equivalent of audio recording.
So like in Blackmagic RAW files, or in ProRes RAW,
in reds RAW files, or like we're used to using RAW files
when you are taking photos, there is a ton of flexibility.
You can push and pull stuff.
You can underexpose things and bring things back.
You can have things overexposed and bring things back.
And I saw some stuff with this 32-bit audio
with people showing examples of it,
and I wanted to try it out myself.
And I really thought it would be a useful tool for the type
of work that I do.
So there's a few different recorders that do it.
This is the zoom F6, the new zoom F6
or kind of relatively new.
And the sound devices mix six, mix eight and mix four,
I think, or pre-mix, they're called also,
record 32-bit float audio.
And so within the recorder you can change that.
You can change it so it records a bit rate
of 32-bit float.
Technically, I don't really understand how it works,
but it works amazingly well.
So I want to show you guys how well it works.
I mean, it really blew my mind.
It was as good as I was hoping it was going to be.
So right now I got my nice little Sanken mic on here,
and I'm just going to, I'm going to fix this in post.
So what you guys are going to hear is going to sound okay.
Okay, so you can see the levels on here.
Now I'm just going into input one.
There is six inputs on the F6 and you can see, I am yes,
going into level one here.
And I can just do something here.
I can just play with this.
I'm gonna show you guys, I'm going to get really,
really close to this microphone.
And I'm going to make it clip,
like this is not optimal at all.
This is a very bad.
I can also play with that by adjusting the recorder itself
and bringing this way up.
And that is totally clipping.
But what you're going to be listening to is probably not
going to be sounding too bad.
And I'm going to show you on the computer, how I fix this.
So we're also going to do the opposite here.
I'm just going to talk really, really quietly.
You know, there's sometimes you do interviews with people.
They don't know how to project their voice at all.
So we're gonna go into the computer right now and I'm going
to bring these files in that I just recorded there.
Those blowing out and super low files.
And I'm gonna show you how I made them sound okay
for you guys, and what they would have sounded like
if I didn't fix them with the 32-bit float.
And you're just going to see the magic of how well
this crazy stuff works.
So now I have these files on the computer here,
and I'm going to show you what it looks like on these files.
So if I open this up and we're going to go over
to the audio meters here, just so you can see.
If you look at it really closely,
you can see how clipping these are.
And these kind of get worse and worse here.
I don't want to wreck your ears here.
So I'm just gonna play a little bit,
and I can just do something here.
I can just play with this and just show you guys
I'm gonna get really close to this mic.
Like that's bad, that's pretty, really bad.
Like really clipping.
This stuff I don't know if it will be able to bring it back
to the 32-bit float, we'll be able to bring
this back or not 'cause this is like, like it's crazy.
Now little bit farther in here we're going to go
to that stuff where I was talking super softly
and you can see how low these files are here.
Like, look at how small those wave forms are.
Look how low this is.
That this is crazy, crazy low.
So let me show you how to do this,
how to adjust this and fix this.
It's very simple.
We're going to jump over into Audition from Premiere.
So you can just right-click on this.
And if you have Audition installed from the creative cloud,
you'll be able to see it here.
Edit clip in Adobe Audition.
Adobe Audition is going to open up.
Okay, so now Adobe Audition's opened up and you can see
it's as simple as kind of isolating an area.
So I'm going to take that stuff that's really bad,
that's really bad.
Let's see if I can bring this back.
And you've got this dial here in your DB,
and I'm going to bring this back.
Whoa, whoa, like let's see.
This was like, you know, completely clipped.
And let's hear this now.
Order itself and bringing this way up
and that is totally clipping.
But what you're going to be listening to is probably not
going to be sounding too bad.
And I'm to show you on the computer.
I mean, this is crazy, this is mind blowing.
That was did you see like was it was, that's the before.
It's all clipped, it's all clipped.
This is not like the speakers won't even play
because it's so loud, it's so blown out.
Now when you go edit, redo, boom, it's back, it's back.
And it works, often bringing this way up at that.
So, you know, you can highlight another section here.
I can bring this down again.
I can dial this,
bring this all back down to a good kind of happy level.
Something I can play with in Premiere, bring this back down.
And then that stuff where I was talking really softly,
let's bring this up.
Let's see how we can get this to sound.
Oh, well let's bring this up a bit more.
Let's see, see how this sounds now.
I'm just going to talk really, really quietly.
You know, there's sometimes you do interviews with people.
And so, I mean, I was talking really close to the mic there,
so it's not going to sound great with that.
But you can see how you can bring amplify some stuff
that was recorded really way too low.
Don't know how to project their voice at all.
And you'd ask them like, can you guys please project
your voice a bit more?
And that's it, I just go file save file.
And I'm going to quit Audition.
I'm going to get back into Premiere and you're going to see
it's updated in Premiere here.
You guys can probably see why this really got me excited
and how it like made my brain explode when I really first
tried it myself because of the way I work.
And I'm sure a lot of you guys kind of work a lot
of the same way when you're out doing recording
and you're doing interviews and you're doing things.
A lot of times you don't have the full crew
that you would need.
And sometimes even when you do,
there's still some errors that can happen.
And it's still hard to monitor things all the time.
For myself and especially more so going into
the season right now, after, during the COVID crisis,
I'm sure I'm going to be going out more and more
as a one-man band.
You know, that's kind of how production I'm going to see it
going a lot forward for the time being right now.
So I am going to be doing more and more of my sound myself
and directing myself and shooting myself.
And, you know, that was kind of one of the reasons why
I invested in this new recorder for the 32-bit float
is because it helps me that way.
The same way auto-focus helps me on the FX9
when I'm doing interviews and I can't always be looking
at the monitor because I'm focused on doing the interview.
The same way when I'm doing an interview like that
and I want to be directing it I don't want to always
be really focusing on the audio.
If you're you can't focus on all those things,
the way that they need to be focused on
and be focusing on what you're shooting
or your content or directing what somebody's saying,
especially during an interview situation.
So a tool like this is super, super helpful,
especially if I have a bunch of people mic'ed.
if I have a few people with a lapels on,
I'm using a boom, this is awesome.
I don't really have to worry too much at all
about the levels.
Okay, you're still gonna have issues.
You could still have issues of clothes rubbing
on a lapel mic.
There could be people who are still gonna hit the mic.
You're going to have stuff like that.
But for a lot of things, when you're levels
and playing with different levels and if something happens
that's really loud and, you know, booms
and kind of clips your audio, this is a huge tool to have.
So let me know what you guys think on this video
on 32-bit float audio.
Have you guys tried out 32-bit float audio yourself?
Is this something that you're looking at investing in
and getting a tool that can record 32-bit float audio?
It would be awesome if they somehow they could
have 32-bit float audio inside of a camera
when you're recording as well.
But this is an awesome tool.
Thanks so much, guys.
