Have you ever wondered: what is the best song instrument Splitter? Maybe you're seeking answers to the questions:  what is the difference between Logic Pro and Gaudio, how do you separate songs into stems, how do you extract stems from Logic, what is an AI stem splitter or maybe just what is a song stem splitter? Then check out EP 154 of the Inside The Mix podcast.

Discover which stem splitter reigns supreme as I dive into a detailed comparison between Logic Pro's stem splitter and Gaudio's stem splitter. I reveal the strengths and weaknesses of each tool, especially when dealing with key elements like the kick, snare, and reverb tails in a synthpop remix. Learn how Logic Pro maintains the kick's power but struggles with phase issues and muddiness, while Gaudio offers a balanced high-frequency output but sacrifices some snare body. Your remixing needs could be transformed by understanding these nuances!

In the latter half of the episode, I venture into the intricate handling of guitars, synths, drums, bass, and vocals during a chorus. Hear firsthand how Logic Pro falters with guitar prominence and synth clarity, whereas Gaudio delivers a fuller, more vibrant sound.

Marc Matthews (00:05):
Hello and welcome to the Inside the Mix podcast.

mastering engineer.
You've come to the right placeif you want to know more about

I've been writing, producing,mixing and mastering music for
over 15 years and I want toshare what I've learned with you

(00:27):

And to the returning listenersand watchers on YouTube, a huge
welcome back.

(00:47):
So just this week I wasapproached by a new client
inquiring about a remix projectand they were inquiring as to
whether I could remix a ballad.
The client only had a final mixwith the vocal and piano

(01:09):
embedded in this final mix, sothey didn't have the separate
stems.
Now, if you are a follower ofthe podcast, you will know that
in a previous episode I demoedthe Logic Pro stem splitter.
But it got me thinking.
Is there a better alternativeout there?
So I did a quick Google searchand I searched basically for

(01:29):
best stem splitters, 2024,something along those lines, and
the one that came top of thelist in this particular blog
post was G-Audio and itimmediately sort of stuck out to
me because it said free onlinestem splitter and it transpires
that it is no longer free.
There is a 20 minute sort offree trial, but I'll go through
that towards the end of thisepisode.

(01:50):
So this episode is about demoing, or rather contrasting, the
Logic Pro stem splitter versusthe G-Audio stem splitter.
I'm fairly certain that's howit's pronounced, although I went
on this on their YouTubechannel and I think they've got
an automated voice that saysGaudio, but I'm fairly certain
it's Gaudio, but correct me ifI'm wrong.
So this episode is going to bean A-B comparison of the Logic

(02:12):
Pro stem splitter versus theGaudio stem splitter.
So I'm not going to demonstratehow to split the stems in
either platform Logic Pro orGaudio.
It's already done and the stemsare in the project.
But if you want to learn how toactually use the stem splitter,
then check out episode 144.
Is Logic Pro 11's stem splitterany good?
And there is a YouTube videoand you can also listen to it on

(02:35):
your podcast player of choice.
So let's dive into thecomparison.
So here we are in the Logic Proproject and I've got it set with
the original mix right at thetop of the project, and the mix
in particular is my track calledAlive, so it's the same one
that I used in episode 144 ofthe podcast.
So it's the first song off myfour track EP, which was

(02:55):
released in 2023.
And I'm actually working on newmaterial now, so I should.
I will rather have some newmaterial coming out in the next
few months, in 2024.
So, yeah, I've got the originalmix at the top and I've got
this section.
I've got this loop set up here,so I'm going to play this.
This is the section that we'regoing to be comparing throughout

(03:17):
these different stems.
So this is the original mixwithout any splitting.
There we go.
I love the vocals in this track,so smooth and mellifluous.

(03:38):
So we're going to start withdrums first.
So let's dive into the drumsand the stem.
Splitting of the drums.
So this is the original drummix.
So what I'm really listeningout for in these stems is the

(04:02):
kick.
Has the power.
Is the power of the kick still?
There Is the attack of thesnare there, the power again of
the snare, and I want to hearthe reverb tails and also just
the tails in general of thecrashes as well.
So let's give it a go.
So I'm going to start withLogic Pro.

(04:23):
This is the Logic Pro stem.
So listening to that, there thekick sounds pretty good.
The snare sounds a bit phaseyin places.

(04:44):
It got that kind of going sortof sound and the percussion it's
there, but the tails againsound a bit phasey when they're
coming in and out and you canalso hear some of the other
instruments really low level.
Now, admittedly, when you'redoing a remix or something using
this stem, that will get lostin the wash right when you put
all the other instruments inthere.
But let's it again.
This is the logic one.

(05:04):
Yeah, it's kind of.
When it gets to that chorussection and the instrumentation
changes slightly, then it soundsa bit phasy.
The kick is there, though Ithink it's retaining the power

(05:26):
of the kick and the snare, butit just sounds a bit muddy.
It sounds a bit muffled.
I mean, this is AI, right, it'sseparating the stems.
It's never going to be perfectin representation or comparison
to the original, but it does apretty good job.
So let's have a listen to theG-Audio split stem.
So this is the G-Audio one.

(05:58):
Now.
Here the kick sounds okay.
The snare has lost its body.
The snare has certainly lostits body.
It's like there is a low cut orhigh pass filter put on it the
phasing or the phasy sound.
It might not be phasing, butthat's what it kind of sounds
like.
Right Is less prominent and I'mfinding the sort of the tail of
the percussion is extending outa bit more as well.

(06:19):
So I'm getting a bit more ofthat percussion it's not and
then dying out, as it was withthe Logic Pro one.
So let's listen to the G-Audioone again.
I'd hazard a guess and saythere's more sort of higher

(06:44):
frequency information presenthere in this one.
It sounds a bit more balanced.
It kind of sounds more balanced, but it does sound like it's
lost power.
So I'm going to play the LogicPro one again.
Now I'm going to play theG-Audio.

(07:12):
It's a tricky one for this.
If I was going to choose myfavourite of the two, I'd go
with the Logic Pro for the kickand the snare and then I'd go
with the G-Audio for thepercussion, for the higher
frequency information.
If I was going to select one orthe other, if I had to, if I
didn't want to sit on the fence,I'd probably.

(07:32):
I'm going to go with Logic Profor the drums on this one.
But let me know what yourthoughts are.
Leave a message in the commentsor send me a DM at
InsideTheMixPodcast.
You can do that for all ofthese as well.
I'm not going to repeat itthroughout, but let me know your
thoughts.
But yeah, on this one here I'mgoing to go with Logic Pro as
the winner of the drum stemsplitting.
So now we move on to bass, andthis will be an interesting one

(07:54):
because there is real bassguitar and there's also synth
bass in this bass stem.
So let's have a listen to theoriginal bass mix.
So what I'm listening out forhere with these split stems, I

(08:23):
want that sort of attack thatyou're getting from the original
, from the actual bass guitaristplaying bass.
On that you've got that sort ofstring attack.
I also want to hear thoseslides between notes as well,
and I also want to hear theseparation between the bass and
the drums in particular.
So let's give it a go and we'regoing to start with Logic Pro

(08:44):
again.
So this is the Logic Pro SplitStem.
So I played it a bit longerthere because I wanted to hear

(09:10):
the beginning again of thissection, and it's retained the
slide between notes.
It's lost some of that sort ofmid-range frequency synth
gnarliness that I got from theoriginal stem and you can also
hear the drums.
You've got that in thebackground kind of like a

(09:30):
metronome, like it's beenrecorded, and you can hear that
bleed through the headphones.
So there is that in there.
It's got that really low levelinformation of the drums.
I'm just going to play one moretime.
It kind of sounds like it's beenrecorded like using a

(10:01):
microphone, but in another room.
The microphone's recording thesound emanating or propagating
from within a chamber orsomething along those lines.
But not bad.
So let's give the G-Audioversion a listen and see how
this one compares.

(10:35):
Now, immediately, my favorite ofthe two is the G-Audio one
straight away, and I think it'sretained a much broader range of
frequencies for this bass, thelow-level information of the
drums yes, it's there a tiny bit, but it's much less.
You've got that slide betweennotes of the bass guitar and I
think, importantly, it'sretained some of the
characteristics of the synthbass in particular, which is

(11:01):
what I really wanted in this.
So an easy one, not going tosit on the fence at all with
this one.
G-audio wins it for me for thebass stem splitting.
So now we move on to the mostimportant part of this episode
and that is the separation orthe splitting of the vocal, and
it's the reason I put ittogether, really, because I
wanted to see if there were anybetter or any alternatives to
the Logic Pro stem splitter forthis project.
That.

(11:33):
I'm working on for a thetime-based processing.
So you've got the reverb and thedelay in there as well.
Now, admittedly, I don't knowthe process of splitting stems

(11:56):
and how much it attenuates thetime-based processing, but I
just want to hear thatsmoothness of the vocal coming
through in this and also theseparation between the vocal and
, once again, in particular, thedrums.
Are we going to get bleed fromthe drums in this vocal, kind of
like you would do when you areplaying a scratch track to a

(12:16):
vocalist or an instrumental, andyou get that bleed through the
headphones?
So let's have a listen to theLogic Pro one.

(12:39):
Now, immediately you can hearthat sort of metronome sound
from the drums in the background.
So you've got that comingthrough.
But again it's going to getlost in the wash.
Really, it sounds like it'sattempted to I say attempted,
attempted is the wrong word butit has attenuated the time-based
processing.
But I think in doing so you dohave elements where it sounds
almost like the vocal issign-chained to something

(12:59):
because it ducks out slightly.
You get that sort of soundReally weird way of describing
it.
But let's play it again.
I think there it sounds prettygood to me.
I think it's lost some body ofthe vocal.
It sounds a bit thin and a bitweak.
But let's play it again andI'll continue on into the actual

(13:22):
chorus section.
Yeah, it's there In between thephrasing of the vocal it's
ducking out.
It's kind of like almost like agate, but it's overemphasizing

(13:43):
it slightly.
And you've got some of thebacking vocal coming through,
but not a huge amount.
It's that main lead vocalcoming through there, so not bad
.
Let's have a listen to theG-Audio one Now.

(14:11):
Immediately.
I'm liking the G-Audio versionhere.
I think it's got more body tothe vocal.
It's got more of the time-basedprocessing.
Now, this is a key point.
It really depends on how muchyou want of that time-based
processing in the splitting ofthe stems, because you might
want it to be really dry andapply your own processing, in

(14:31):
which case the G-Audio one mightnot work.
In this instance you mightprefer the logic pro one because
it is drier.
But if you did want thattime-based processing, you
certainly get more of it withthe g audio and there is less of
the drums coming through.
So let's play it again.
Yeah, certainly in that chorussection you're not getting that

(15:00):
sort of ducking effect that wewere getting with Logic Pro and
it just sounds a bit more lushand you're getting more of that
vocal and there's more body toit.
It sounds more powerful.
So in this instance hereG-Audio wins it.
So at the moment it's 2-1 toG-Audio.
So we had Logic Pro won thedrums, but G-Audio has won the
bass and the vocal.

(15:21):
Can Logic bring it back withthe other?
Let's have a look, or rather alisten.
So let's play the other stem.
Here we go.
This will be interesting.

(15:48):
I wonder how it retains the panpositioning of the synths.
And also, we've got guitar inthere as well.
There's not a massive amountgoing on.
We've got a couple of synthsand we've got guitar.
I kept it quite stripped backin this instance.
So let's have a listen.
This is Logic Pro Now, leadingup to the chorus.

(16:25):
It doesn't sound too bad.
When it gets to the chorus, Ithink we're losing quite a lot
of the guitar in particular.
We're losing a lot of thatguitar.
Again, we've got drums comingthrough underneath and it kind
of just sounds.
The synths sound slightly muted, they sound muffled to me in
particular, but we've certainlylost a bit of that guitar.
I'm just going to play theoriginal again and then I'm

(16:47):
going to play the Logic Proversion.
Now, in that build-up to thechorus there, where you've got

(17:11):
the riser, the guitar is quiteprominent.
you've got this really nice sortof bell sound as well.
Are we getting that?
with Logic Pro.
Now, again, you're kind oflosing it, aren't you?
You're not getting those higherfrequency, those lush synth
sounds with Logic Pro.
So it's okay, let's give theG-Audio version a go and see

(17:40):
what this one sounds like.
Now, straight away, when thatchorus kicked in there, I would
say in the pre-chorus, thepreamble leading up to it, it's
quite similar to Logic Pro.
But when the chorus kicked in,you've definitely got more of

(18:03):
those lush synth sounds comingthrough.
It sounds fuller, sounds biggerand it just sounds more
luscious and vibrant as well.
So I think Geordio is winningit there on the synths.
But what about the guitar?
Let's have a listen to theguitar.
It's a nice g audio.
Let's listen to logic pro.
It's not much in it, not muchin it at all, I think.

(18:28):
With the guitar and inparticular I was going to
mention this, why, rather?
I said before we did thecomparison about the panning it
has retained both, as both haveretained the panning positions
of these instruments.
But there's not much in it withthe guitar, although I think
I'm leaning towards g audioagain.
But am I biased now?
Because it's one, two out ofthe three tests we've done so

(18:49):
far, maybe, maybe, possibly, butI think when it gets to the
chorus with other G-Audio, Ithink does win it.
So let's play it again withG-Audio.
Yeah, it's just those sort ofhigh mid frequencies you're

(19:16):
getting.
It's just higher frequenciesagain of the synths.
It just sounds a bit nicer tome.
It's more pleasing on the earwith the G-Audio.
So again, easy decision here.
I think G-Audio wins it.
So that puts it three to one.
G-audio is the winner with thisone here.
So we had Logic won the drums,then G-Audio won the bass, the

(19:38):
vocals and other.
I think in general Logic Prowon the drums because it
retained the power of the kickand the snare.
But then with the bass, vocalsand other, I just found that
G-Audio sort of retained thewarmth and body of the vocal and
the synths as well, and thebass.
To be honest, it just soundedmore rounded and fuller compared

(20:00):
to Logic Pro.
I felt that Logic Pro wasattenuating too much.
However, the stem splitter is afeature of Logic Pro, so it does
come with Logic Pro.
Obviously, you can only use itif you've got Logic Pro 11 and
you've got an Apple Silicondevice.
I get questions on that a loton a couple shorts that I've put
on YouTube.
So check out my YouTube channeland you'll find them.

(20:22):
It's like a stem splitterchecklist or something along
those lines.
So it does.
I was going to say free.
Logic isn't free, butemSplitter is free with Logic.
I guess you could say it's partof Logic Pro, so it's there if
you need it and it does do agood job.
If you're going to be remixinga lot of the points that I've
picked out, they're going to getlost in the shuffle in the mix

(20:42):
anyway.
With G-Audio, on the other hand, you get 20 minutes free or
free credit and then you have topay for credits beyond that,
ranging from studio 50 I'mlooking at my notes here to
studio 1000.
However, with g audio you canseparate guitar and piano.
Now I didn't do that in thisinstance because I wanted to
compare apples to apples.
It didn't make sense to have aguitar and a piano split in

(21:05):
there because you cannot do thatwith logic pro.
So there's pros and cons toboth pro Pro with the stem
splitter, and Logic Pro is thatit is part of Logic Pro.
The con with that is you doneed to have Logic Pro 11 and an
Apple Silicon device.
The pro with G-Audio is thatyou've got the additional guitar
and the piano and, just ingeneral, I think the stem

(21:26):
splitting is better.
However, you do have to pay perminute with credits for that
and you can check that out ontheir website, but you can try
it for free for 20 minutes, butdo note that the free trial is
only MP3.
It will only spit out MP3 stemsfor you.
You won't get the WAV versionuntil you start paying for

(21:47):
credits.
There are other considerationsYou've got.
I don't know if I pronouncedthis correctly, so I'm going to
say it L-A-L-A-L, dot, a-i la-lamight be how you pronounce it.
And there's also BandLabSplitter as well.
So two notable mentions to goand check out.
Maybe I'll do a video on thosefurther down the line.
And, as I mentioned at thebeginning of this episode, if

(22:09):
you want to learn how to use thestem splitter, check out
episode 144,.
Is Logic Pro's 11 Stem SplitterAny Good?
And, folks, please do leave acomment, if you're watching this
on YouTube, as to your thoughtson the stem splitter and the
comparison that I've done, orsend me a DM at
InsideTheMixPodcast on Instagram.
Happy stem splitting.
