if you're trying to improve the audio captured using your GoPro Hero seven
black without using the external mic adapter and mic it's pretty expensive
then the Brusfri noise reducer app might be what you need the GoPro Hero
seven black is an amazing all-rounder device and I use my own all the time but
the audio capture like many devices around this size isn't all that great
well that's actually a lot better than other small cameras and previous
versions of the GoPro this video shows you how to improve that by using the
Brusfri noise reducer app on iOS hi I'm Sarb Johal and welcome to my channel
which is all about mobile and 360 video and photography and how to edit for
great results in this video I'm going to be talking about the Brusfri noise
reducer app and showing you exactly how you can use it in your workflow and just
a quick note it's only available on iOS for mobile devices though you can get a
plugin for desktops too which is a separate cost this tutorial is all about
using the app on iOS and make sure to stick around to the end of the video
where I tell you how you can sync external audio quickly and easily to the
video you capture if you decide that the internal mic really isn't up to the job
and you need a better audio track and while you're watching make sure you let
me know your best tips for capturing better audio on your GoPro Hero 7 black
what tricks are you that it's always interesting to hear about the experience
of others and your tips and suggestions may help others make improvements on the
audio captured on their GoPro Hero 7 and I'm sure they'll be thankful ok let's
jump to it the iOS app from Brusfri is described as an advanced audio noise
reducer with a simple and straightforward interface and I think
that's a pretty fair description it seems to be very well-suited for
cleaning up noisy audio recordings while retaining sound quality and unlike many
other noise reducers on the market bruce free says that it doesn't mess with
audio facing to suppress noise and comes with often side effects that are quite
noticeable instead it says that it uses in multiple fine-tuned gates to silence
unwanted noise that's what they say so how do you use it and what effect
does it have on recorded sound let me walk you through when you first open up
Brusfri use the main interface screen with the ear
in the center you press this when you come across a section of audio that has
the part that you'd like to suppress or remove from the recording leaving
cleaner audio the different tweaks and settings for how this is achieved can be
accessed by swiping left and right swipe left and you find the screen labeled
expanders this seems to refer to the threshold of which noise reduction kicks
in with a lower value meaning more noise reduction applied swipe right past the
learn screen and you see the filter screen including age high and hpf edge
controls the intensity of reduction with a lower value giving a smoother
reduction effect not as harsh as it could otherwise be high seems to boost
high frequencies and hpf reduces lower frequencies if we swipe back to the main
screen the way Brusfri works is that you find a section of audio that has the
part that you'd like to suppress or remove from the recording to leave that
cleaner sound this seems to be need to be at least a second or two long for it
to work well and that needs to be relatively clean background audio
uncontaminated by what you want to leave behind once you find that section of
audio press the ear and the Apple learns that section of audio and then uses its
algorithms to remove or suppress that particular audio you can have multiple
passes at that process and Brusfri can relearn on each pass until you're
happy with the results making the necessary tweaks with the other settings
that I've already covered once you're happy with the results you can export
this audio in different formats in different codecs WAV AIFF and mp4 and at
different bit depths too that way you can replace the audio in whatever media
you're using with this new clean up audio video mp3 whatever it is that
you're doing and export it directly into different apps on your iOS device
- it's actually pretty simple to use and well integrated all right now you know
how to use it how does it before I've recorded two samples here for you to
make a judgment for yourself the first one is in an echo we'd carport with some
background wind noise so you can see how it performs with a constant background
check it out now and Here I am with the GoPro in a not quite so windy
environment let's try 1 2 3 4 5 an hour let's apply Brusfri 1 2 3 4 5 what do
you think I actually think that did a very good job of cleaning out the audio
my voice sounds pretty rich and most of that echo has gone although it does
sound a little bit squelchy at the end I wonder if that's because the GoPro might
have been trying to suppress the wind noise - okay what about a really
challenging noisy and changing wind environment now I warn you now that it's
a pretty noisy recording coming up so if you're listening to this quite loud or
in headphones you might want to turn it down a little right now okay ready now I
don't think that was too bad at all in fact I think it does an amazing job
given the circumstances and you're able to pick out my voice much better from
the background wind okay it's recommendations in summary time
just before I tell you what you need to know about using that external mic and
how syncing to your capture video can be done really easily if you're looking for
a way to improve the sound captured by your GoPro Hero 7 flat using a simple
app that's really well integrated into the iOS system and means that you can
replace the audio in your video with a cleaned up version really easily then
you should definitely consider the Bruce free noise reducer in situations with
moderate background noise where you can get a good clean sample of the noise you
want to reduce then it produces pretty great results with the GoPro Hero 7
black however we've noisier more challenging environments such as high
winds the Brusfri app improves the sound enough so that you can pick out
your voice much better against the howling wind it's not perfect but it
does a very reasonable job in a testing environment and some I
think it's an app worthy of your consideration
that's $14.99 it's very very good but it can't work miracles what did you think
about Brusfri from what you saw in the video be sure to leave me a comment
below and check out the links in the pen comment to see the other devices I've
tested Bruce free on you might be surprised at some of the results so if
you're looking to capture sound and then sync it with your external mic in your
video and replacing that audio captured in the original video and you have
access to Adobe Premiere Pro check out my card link above here now for a very
easy way to sync and replace your soundtrack in just a few easy clicks now
I've heard that you can also do this in other software packages like DaVinci
Resolve so you might want to check that out too I'll leave a link in the
description to this video hey I hope you've enjoyed this video my name's Sam
Joe hell if you have found this useful please consider giving it a like and
perhaps subscribing to I'd love to see you back here again soon here's some of
