00:00 hello everybody and welcome to a short
00:02 tutorial on how to use noise gate to
00:04 remove the breathing sounds in your
00:07 audio recordings for this I use audacity
00:12 2.0.1 it’s a free software very easy to
00:15 use so you can try it in that yourself
00:18 to do what we want to do i made a test
00:22 recording which sounds like this this is
00:25 the test recording i hope you like it
00:28 and as you can hear there is pretty
00:31 intense breathing in that recording
00:34 which is not good at all especially if
00:36 your audience is using headphones to
00:38 listen to you this breathing is directly
00:41 in their ears it’s not very pleasant to
00:43 listen to so we want to remove that the
00:46 first thing you want to do is go up here
00:48 to audio track and select waveform DB so
00:52 now you can clearly see wow there is a
00:55 very loud breathing in this recording
00:57 let’s remove that to do that select a
01:01 part of your recording to test it and go
01:06 to effect and down here it says noise
01:09 gate and here this is also why we
01:13 switched to waveform DB is because now
01:16 we have on the left side here is a scale
01:18 from 0 to minus 60 that we use to make
01:22 these settings here I use the gate
01:24 frequency above zero so anything gets
01:28 filtered by the noise gate level of
01:32 reduction you can choose what you want
01:35 to choose do you want to remove the
01:37 complete breathing sound or just lower
01:39 it a little bit mostly I just lower it
01:42 because breathing is natural and if
01:44 there is no breathing sound at all you
01:46 will sound like a robot so that’s not a
01:48 good idea just remove a little bit of it
01:50 now check in your recording on average
01:53 high or how high the breathing sound is
01:56 going in the scale on the left side
01:59 compared to the rest of the recording
02:02 that which is your speech basically yes
02:06 and this will of course also remove any
02:08 other noise that is below that so if you
02:11 have other sounds that are below that
02:12 they of course will also be lost so this
02:15 is just for audio speech recording and
02:18 other things I don’t know I can’t tell
02:20 so as we can see this is almost at the
02:24 level of 33 so let’s use this as a
02:27 setting 33 on the gate threshold so this
02:33 is where the gate is activated
02:34 everything that is higher on the – part
02:38 then 33 so this quest part that attack
02:44 decay is how fast this is going to be
02:48 activated and so you don’t want to set
02:53 this too low because then it will jump
02:55 inside if you’re breathing in the parts
02:57 that are higher or lower so it doesn’t
03:00 work that well it’s just set it on a
03:01 average I used 250 milliseconds for that
03:05 in this example you can just you have to
03:07 test around what works best for the
03:09 recording you can then use it on the
03:11 whole recording and see how it worked on
03:13 the other breathing’s and and then redo
03:16 it if it didn’t work at that well let’s
03:19 test it here and yeah looks pretty good
03:24 so the breathing isn’t completely
03:26 removed but it’s much lower than before
03:28 let’s listen to it again this is a test
03:31 recording I hope you like it
03:34 not so bad we could do it even lower so
03:38 I go to edit and undo then I go back to
03:41 the effect of noise gate and just sets
03:45 the level reduction to a higher value on
03:47 the – degree let’s make it – 27 and as
03:53 you can see now it’s completely gone so
03:55 let’s listen to it this is a test
03:57 recording
03:59 I hope you like it no breathing at all
04:01 it’s if you like it like that
04:04 it’s okay but a little bit of breathing
04:05 is human so you want to keep a little
04:10 bit of breathing in there as you could
04:12 see you right now other stuff like the
04:15 beginning of what you say will also be
04:18 cut a little bit but I think it doesn’t
04:20 sound that bad if you go and do again
04:23 you can see here in the beginning in the
04:25 first seconds here there is where you
04:28 your voice sets in and this will also be
04:31 cut a little bit but mostly that’s no
04:33 problem as you can hear just redo the
04:36 noise gate and well listen to it this is
04:39 a test recording I hope you like it
04:43 sounds pretty okay to me I think you
04:45 decide yourself you do your settings
04:47 yourself but this is how it works with
04:48 the noise gate and it’s pretty easy and
04:51 it’s pretty fast and you can use it on
04:53 hour-long recordings of your voice
04:55 podcast whatever you do just be be sure
05:00 to know that all the other noises that
05:02 are also below that part will also be
05:04 lowered in that kind of value so if you
05:07 work with a lot of little sounds
05:09 probably not that useful to you but for
05:12 audio recordings pretty good thanks for
05:15 watching that’s it and see you soon bye
