## Summary

This tutorial explains how to separate music from other stream audio using Audio Router and Voicemeeter Banana, allowing streamers to control which audio reaches their audience and which they hear privately. It covers setup, routing, and integration with OBS for recording or muting individual tracks.

### Key Points

- **Introduction and purpose** [0:00] — Koko introduces a tutorial for streamers to separate music from stream audio to avoid copyright strikes or give audience control over music volume.
- **Required software** [1:10] — Two free tools: Audio Router and Voicemeeter Banana. Audio Router redirects audio from specific programs; Voicemeeter Banana manages virtual audio devices.
- **Installing and restarting** [2:50] — After installing Voicemeeter Banana, restart your computer to see the new virtual audio devices (Input and Aux Input).
- **Set default playback device** [3:01] — Right-click sound icon > Playback devices > set 'VoiceMeeter Input' as default. This routes all system audio (except music) into Voicemeeter VAIO.
- **Hearing audio after change** [4:20] — After changing default device, you won't hear anything until you route the virtual inputs to your headphones/speakers in Voicemeeter Banana.
- **Voicemeeter Banana hardware output** [4:54] — In Voicemeeter Banana, under 'Hardware Outputs A1', select your actual audio device (e.g., audio interface). Then click A1 on both virtual inputs (VAIO and Aux) to hear all audio.
- **Reroute music with Audio Router** [7:50] — Open Audio Router, switch view (File > Switch View) to see applications. Double-click the app that plays music (e.g., Chrome, Spotify) and select 'VoiceMeeter Aux Input' as output.
- **Restart audio engine in Voicemeeter** [9:35] — After changing routing in Audio Router, go to Voicemeeter Banana menu > Restart Audio Engine for changes to take effect.
- **Auto-start Voicemeeter Banana** [10:17] — Set Voicemeeter Banana to run at startup via Menu > System Tray > Run at startup, so you don't have to manually restart it after reboot.
- **OBS audio settings** [11:15] — In OBS, go to Settings > Audio. Set 'Desktop Audio Device' to 'VoiceMeeter Input' (for game/system sounds) and 'Desktop Audio Device 2' to 'VoiceMeeter Aux Input' (for music).
- **Testing the setup** [12:08] — Plays VLC (routed to VAIO) and Chrome (routed to Aux) separately. Shows in Voicemeeter and OBS that audio appears on correct tracks.
- **Using separate audio tracks in OBS** [14:08] — Record on two tracks; mute the music track in editing to create highlight videos without copyright music. Alternatively, mute music for stream only (audience hears nothing) while you still hear it, or mute music for yourself only while stream continues to hear it.

### Conclusion

With Audio Router and Voicemeeter Banana, streamers can easily separate music from other audio, offering flexibility for copyright-safe highlights, audience preferences, or personal listening control.

## Transcript

hey what's up YouTube this is Koko and
I'm making a tutorial today I usually
don't do these but I'm making a little
tutorial for streamers and basically the
tutorial is going to be on how to
separate the music that you play in your
stream from the rest of your stream
audio so you know why would you want to
do this well let's say you're streaming
and you got like some copyright music
going obviously you're not supposed to
be doing that but I mean you know it is
if you've got copyright music and you
want to make let's say stream highlight
video you're not gonna want that
copyright music in your stream highlight
video cuz then you risk you know
something like a copyright strike so
you're gonna want you're gonna want to
remove the music for that or let's say
you're streaming and you know your
audience doesn't want to hear music they
don't maybe they don't like your taste
in music but you really want to listen
to what you want to listen to you can do
that with what I'm about to show you or
the opposite if your if your audience
wants music and you don't want music
same thing you can do that as well so
how do you how do you accomplish this
well basically with these with these you
can see these two pieces of software
that I have right here this is audio
router and this is Boyce meter banana
now let me just full disclosure I am NOT
a pro at using either of these this
one's pretty simple audio router voice
muted banana is you can do quite a bit
with this program and most of the these
features the functionality I'm
completely ignorant of I'll be honest
but I do know enough to to do what I'm
about to show you okay
so how do you get these programs
basically oh here we go
so here's Audio router pretty simple
just just Google Audio router I'll put
the links in the description there
should be a github link you just go here
there's a 64 bit exe download link and a
32 bit exe download link yeah anyway get
the one that you need it's their voice
meter
banana here we go so yeah you can see
all these pictures this program does
like a million-in-one things okay I
don't use it for any of that there's
tons of stuff on YouTube if you really
want to learn the ins and outs of this
thing you can figure it out you know I
don't know it looks a little complicated
but there's an info out there if you
look so anyway just wait where was the
air it is so you have to install it
there's a little bit they have it they
have a compressed version of it and then
they have just the straight exe just
download exe install it once you've
installed that it's probably going to
tell you you need to restart your
computer so do that and then when you
come back you know you'll have both of
these things here and the first thing
that you're going to want to do is
you're gonna want to change your default
audio playback device so how do you do
that I was showing it to you right here
just right click this little this little
sound icon up here in the corner
go to playback devices obviously I have
my taskbar up at the top yours windows
by default has at the bottom but you
know how to find it come on alright so
anyway you just go there go to your
playback devices and what you're gonna
see is you're gonna see two new devices
that voice meter installed one is called
input right just straight up input and
then one called aux input just explained
to you right now what we're trying to
set up so what you're trying to do is
you're trying to have all of your stream
audio - the music be directed to this
voice meter input device and then what
you want to do is you want to have your
music going to this aux input that's
basically what we're gonna be setting up
okay so first thing you need to do is
you need to set this as your default
playback device just click on it again
input not the aux input click on it hit
set default hit apply then hit OK
obviously I've already done that so I
don't need to do that now now just be
forewarned once you do this you will not
be able to hear any audio on your
computer right because you've changed
the playback device
so you too in order to hear this voice
meter input in whatever you're using to
listen to your computer's audio right
I'm using earbuds right now that are
plugged into my audio interface here on
the desk in order to listen to it on
that or in speakers or whatever you got
you have to route that to or you have to
send that to your your listening device
in voice meter banana so as you can see
in this in the program here when you
open up voice meter banana you're gonna
see here two virtual inputs right
there's virtual inputs right here
there's one right here it's this whole
thing and then there's another one right
here right next to it so as you can
probably tell this one that says voice
meter VA IO corresponds to this device
here the one that you made the default
playback device this one right here
voice meter ox corresponds to the aux
input which is where we're going to be
sending the music you know that we're
trying to isolate from the rest of our
stream so in order to you know hear both
of these things right your desktop audio
and your music you're gonna need to
route both of these to your headphones
or speakers whatever so the way you do
that is up in the up in this side the
right side of voice meter banana you'll
see there's hardware outputs you'll see
this they give you a choice of 3 a 1 a 2
a 3 all I do is I go to a 1 click that
and I select my audio interface now
you'll see there's there's multiple
selections for your figure there
probably will be multiple selections for
your device so I have one here alright
says WDM there's another one here KS
there's one right here Mme and then I
believe this one is also going to my
audio interface I don't really know what
the difference I'll be honest I don't
know what the difference is between
these different things I believe they're
like different drivers like there's WDM
there's KS there's Mme there's ASIO I
don't know what the difference is I do
think they differ in terms of latency
and I've heard that WDM
pretty good in terms of being low
latency and a lot of the tutorials I've
seen people are using WDM so I just use
it it works so yeah try that if you have
issues with that you can try a different
driver like enemy or something but
anyway so that's all I do I select the
device that I'm listening through right
which was probably your original default
playback device right I put that in a 1
then in order to send both of these
virtual inputs to a 1 you just click a 1
right so I think by default it's like a1
and b1 for for everything you don't
really need the b1 so I just make sure
that a1 is clicked for both like that so
both of these virtual inputs will now be
sent to whatever device you're listening
to so now you'll be able to hear you
know whatever audio is playing on your
computer ok so we've got now at this
point you've got most of this you know
you've got most of it working the way it
should
except for you still have not sent your
music to the aux input so how do you do
that use audio router right this is the
the final key the final piece to the
puzzle rather so when you open it you'll
see this which is this is a pretty this
is pretty nice view there's a couple
different views but you can you can see
this shows all of the devices the audio
devices on your computer and it has like
volume meters so you can do like a
little bit of mixing here but I prefer
this view if you go to file switch view
you can go back and forth if you switch
view you can see a list of applications
that are playing audio right so as you
can see on the on the right in this
window it says routed to so it shows you
where each of these programs is
directing its audio to so right now
they're all blank alright as you can see
there's nothing here that just means
that all these programs are sending to
the default playback device so if you
want to change one of them right for me
when I play music I'm usually playing it
it made like a YouTube playlist
on Chrome so for this tutorial I'm gonna
be directing the audio from Chrome to
divert the voice meter aux input if
you're using Spotify or you're playing
VLC like a playlist in VLC you'd want to
direct the audio from that program to
the aux input okay so to read to reroute
the audio you just double-click on the
application that you are gonna use to
play music okay
double-click change it from default
audio device to voice meter aux input it
ok now you'll see it will show that it's
now routing the audio from that program
to the aux input ok and yeah at this
point we're good now one thing to
mention is when you make changes to the
audio routing in an audio router voice
meter banana doesn't automatically see
that change that you made right it's not
detecting like you know any changes to
the audio routing so in order for voice
meter to see it you have to hit menu and
restart audio engine right at this point
now voice meter we'll see what you did
and now all the audio from Chrome will
show up here in the voice meter ox input
everything else game sounds system
sounds everything is gonna go through
voice meter Vai oh okay sorry there was
one thing I almost forgot to mention so
as long as voice meter input is selected
as your default audio playback device
every time you restart your computer
you're gonna need to have voice meter
banana open in order to hear this in you
know your headphones so one thing I
would recommend is when you hit menu
click this option right here system tray
run at startup this makes it so that
voice meter banana always starts up when
you start up windows right which is what
you want so that you can keep this as
your default playback device at all
times right unless you really want to
like go back and forth
switching default devices you know when
you're streaming when you're not
streaming you can do that too but it's
easier just to keep this as a default
make sure that voice muted banana is
that always running in the background
right it's a little bit easier so anyway
that's just a little recommendation I
think we're at this point were pretty
much done so how do you set this up in
OBS this is the final piece of the
puzzle here all right a little bit of
what is this stream-ception smbabybaby
to virtual input second one is the aux
input okay pretty pretty simple to set
this up just go to settings audio you
see right here desktop audio device
desktop audio device to just set those
to the appropriate inputs yeah and so
yeah at this point so yet we're good
here so I'm gonna go ahead and minimize
these things and it with and now I'm
going to we'll do a little test okay
just to show you that it works so here I
have the the YouTube audio library
showing up in Chrome in Chrome so this
is like this is your music basically
this would be like music out play on
stream I mean not really this but you
know what I mean it's just think of it
as it's like an example okay and then
for system sounds okay you obviously be
like game sounds or something like that
but just for the sake of simplicity I'm
gonna open up a song in VLC so both of
these are you know YouTube's audio
library songs so no copyright strike
YouTube okay I'm playing I'm playing
fairly here alright so when I play each
of these what you is actually I'm gonna
show you voice to meet her first okay so
if I play this VLC
okay so now what you can see I don't
know if that's loud
yeah it's loud enough you can hear that
so you'll see it's showing up here right
in the voice meter input okay
I'm gonna pause that and I'm gonna go
here in chrome right that the
application that whose audio is rerouted
to the Ox input I start playing
something in here it's a little bit hope
that's not too loud anyway you get the
point it's showing up here in the aux
input okay so their routing correctly as
you can see and if you if you look in
OBS right a little bit more video
ception
if I start playing in VLC yeah you can
see it's showing up here in the desktop
audio right and then you can probably
guess if I play in Chrome it's gonna
show up in here alright desktop audio -
exactly
see so everything is being routed
properly okay calm down all right all
right
so yeah everything's being routed
properly so with this set up let's say
you want to do a stream highlight
without any of your music included right
in OBS you just need to record your
desktop audio and your desktop audio -
on different audio tracks right and then
when you're within your editing software
you can just get rid of the track that
has the music keep the track that has
your stream audio which would be this
one right desktop audio desktop audio -
has the music and again if you wanted to
mute let's say the the audio for the
stream the music for the stream right so
only you can hear it all you have to do
is just mute like this so I'll play I'll
play Chrome right now I'll play some
music in Chrome okay now if I hit this
okay it should now be muted in the video
I can still hear it I hear music blaring
in my earbuds right now but it should be
silent for you right if I unmute it now
you can hear it again now let's say I
want to do the opposite I want to mute
it for me I'm sick of hearing something
I want to try out a you know pub G or
something I want to hear what's going on
me but the stream wants to listen to the
music you can go into voice meter banana
and all I have to do is mute this aux
input at the very bottom there's this
mute button right now I cannot hear any
music now if you look in OBS I did not
mute it in OBS so the video you guys who
are watching this right now should be
able to hear this music I can't hear
anything it's totally silent so yeah
it's pretty cool and also another thing
if you wanted if you felt like the music
was too loud for you but your stream is
not complaining they think the volume is
fine you can change what you hear with
this knob right here this does not
affect the levels that your streamer
hear right if you look in OBS if I lower
this all the way alright basically this
is pretty much muting it for me I can't
hear anything
but you can still see the levels in OBS
are unchanged so you should be able to
hear it fine no problem you should not
hear any change right and vice-versa if
it's too quiet for you and you just want
to turn it up on your end you could just
increase it like that yeah
alright so that's pretty much it I mean
let me pause this okay so yeah anyway
that is it hopefully this tutorial made
sense I'm sorry this is totally
unprepared I'm just making this video
very quickly so so anyway yeah if you
have any questions or again I'm a noob
if you have Corrections if I did
something wrong here you know feel free
to let me know in the comments below if
I miss something anything like that I'll
be monitoring the comments section if
you liked the video go ahead feel free
to give it a like hopefully this helped
you out I just learned how to do this a
couple days ago and yeah I think it's
it's pretty cool it's really easy to
hopefully the video isn't too long let's
see oh my god this is a long long video
okay I'm sorry I'm sorry I tried to
explain as quickly as I could but anyway
that's the video hopefully this helped
you see ya
