hello it's Patrick here from the GarageBandguide.com if you're just
getting started with mobile music production on iOS then the terms enter
app audio and audio unit version 3 might leave you feeling a bit confused in this
video I'll explain a bit about these audio connection methods and share some
pros and cons of
released in 2013 alongside iOS 7 answer app audio as Apple's answer to audio bus
before enter app audio launched if you are making music on iOS audio bus was
most probably a huge part of your workflow essentially audio boss audio
Bose audio both essentially audio bus is a standalone app that allows installed
and compatible apps to send audio to one another the attraction of enter app
audio / audio bus is that it's already built into the OS there's no need to pay
for and download a separate app in GarageBand you can find a list of inter
app audio apps and the external sounds section of the sound browser tap on
inter-app audio and choose from any inter app audio compatible apps that you
have installed you'll be taken to the audio recorder where you can see a small
icon depicting the inter app audio app that you have loaded tapping this icon
will switch from garage bands interface to your apps interface and there'll be a
button present in the apps interface to switch back you can switch to different
apps by tapping the jack icon and tapping the insert audio tab
one of the biggest things that inter-app audio has going for it as the amount of
compatible apps that you can use with it it's a massive list giving you a lot of
options when it comes to choosing instruments and effects and you can only
have one instance of an Interop audio app loaded on a track at any time though
which does limit your ability to add multiple external effects or load
multiple instances of the same app on a track for me the answer app audio
implementation and GarageBand for iOS is a bit clunky - I'm not really a big fan
of having to switch back and forth between app interfaces when trying to
record or edit projects it's a bit of a faff really
introduced in 2015 with the release of iOS 9 Audio Units audio Genet extensions
audio unit version 3 whatever you want to call it will seem very familiar to
anyone who has used garage bands or Logic Pro for that matter
on Mac mobile music makers no longer have to rely on what some would consider
clunky solutions like audio bus or inter app audio instead apps can simply be run
from within your preferred iOS door just as they would on the desktop platform
the last year to 18 months has seen an explosion in the number of AUV 3 apps
available both new apps and updated versions of old favorites which is good
news and GarageBand you'll be adding your AUV 3 app to an existing track
within a project on the track screen tap the track controls button and tap on
plugins and EQ tap Edit in the top right of the window and tap a green plus icon
to add an AUV 3 app to the slot tap the audio unit extension tab to select from
any audio unit version 2 the apps you have installed or apples on serviceable
but decidedly beige offerings the beauty of audio unit version 3 apps is that
that can be loaded directly into a host app which makes it much easier to change
settings quickly this gets rid of the need to switch between apps this method
also results in far less strain on your CPU there are reports of users finding
that recording and editing on their older iOS devices is a lot snappier and
they see less instances of the dreaded optimizing performance message when
using a UV 3-over enter app audio you can load multiple instances of the same
app on a single track - this is a significant advantage the AUV 3 has over
enter app audio at the time of recording there isn't
quite as many audio unit version 3 apps available as there are ones that are
compatible with Inter app audio but with the meteoric rise of a u v3 over the
last 12 months and quickly becoming the preferred method of linking audio among
musicians and developers alike the list of audio unit version 3 hosts
instruments and effects will continue to grow and grow so it's pretty obvious
which of these methods I personally prefer a u v3 simply makes life easier
it makes creating projects simpler and my workflow more streamlined enter app
audio was a useful workaround solution but definitely of its time and it's
clear to me at least the audio unit version 3 is the future of music making
on iOS
so there you have it in the Battle of inter app audio versus audio unit
version 3 that has emerged a clear winner in my opinion at least what do
you think have I set myself up for a world of pain in the comments section
only time will tell I've been Patrick from the GarageBandguide.com and I'll see you next time bye for now
