Multiple Audio Interfaces: How and Why

Multiple Audio Interfaces: How And Why

Multiple audio interfaces give you the sound quality you need to produce amazing songs, podcasts, or anything else that you want to record.

For those who don’t know, audio interfaces are devices that connect your microphone to the computer.

Computers usually have a built-in 3.5mm mic jack that can help you record music, but the audio quality is not something that you may want.

Despite the little microphone icon next to the mic jack, you shouldn’t be using it to record audio.

If you are going to spend loads of money to get a professional microphone set for recording, connecting it to the laptop with basic hardware can be criminal.

You should take some time to learn how to install multiple audio interfaces so that you have the best quality audio.

Can You Use Two Audio Interfaces At Once? 

Using Two Audio Interfaces

Aggregate devices are designed to ensure that you can use audio outputs and inputs from a different source at the same time.

There are many audio applications that you can use like MainStage, GarageBand, Logic Pro X, and other audio-compliant core applications.

This method will ensure that you can record audio from different mics, all of which will be of high quality.

If you have multiple singers or different speakers on a podcast, then installing multiple audio interfaces is necessary.

To increase the number of audio outputs and inputs received at the same time, you will have to develop and aggregate system of audio interfaces.

This is possible even if you don’t have an application that would support every output or input source separately.

With the applications mentioned above, you will be able to use separate devices for output and input.

For example, with multiple audio interfaces, you will be able to use the headphone jack of the Mac laptop for output while using the USB microphone from another laptop for input.

To set up multiple audio interfaces, you have to make sure all the external audio from the interfaces are connected.

After it’s connected via the Setup process, you can use the multiple audio interfaces with ease.

Just make sure that the audio output for the computer is selected as the audio interfaces.

What Are The Benefits Of Multiple Audio Interfaces?

Audio Sound Card

The biggest benefit of installing multiple audio interfaces is that it is preferred over sound cards.

Sound cards are cheaper to use, but they have limited quality of sound.

They also have very basic output/input configurations that can make them less than ideal for audio recording.

Sound cards mostly just work with stereo lines consumer-grade output/input levels.

They can get a lot of electromagnetic or radio interference, which can add jitters or excessive latency to sound quality. This can greatly reduce the level of quality of your audio.

If you have Hi-Fi speakers, then sound cards can work to playback any compressed audios you have.

But, you will need dedicated audio interfaces to record the audio so that the results are high-quality.

You may also need an easy and quick way to make sure that the output and input audio route is defined and eliminate the costs to the audio that sound cards may have.

Using multiple audio interfaces will ensure reduced latency since the sound doesn’t have to bypass through intermediate layers.

Instead, it has direct access to the sound cards, which can increase the clarity of the sound.

The direct access of the audio to the hardware also ensures that the signals don’t have any interference from the audio mixer of the operating system.

Using Audio Mixer

You will be able to get high fidelity gains since there are no losses from bit rates or sample conversion.

The reduced latency advantage is especially important if you are using multiple audio interfaces.

With multiple sources of audio, you will have even more direct monitoring issues.

For example, the audio signals may be audible through the speaker system without going through the reprocessing in the operating system of the computer.

This can increase latency in the audio, which is why you have to work on reducing it in other ways.

Digital and analog converters are cheap components of the audio system that are often used while recording.

They do little in creating high-quality audio and are directed towards the average layman.

You will need multiple audio interfaces that are dedicated to each input or output source.

This will ensure that you have better music production quality since the audio fidelity will not be compromised.

The bigger size and easier accessibility that multiple audio interfaces provide ensures that you can use a huge variety of audio inputs at the same time.

You will be able to record a large selection of audio through different recording equipment and face no issues with sound quality.

How to Connect Multiple Audio Interfaces?

More and more musicians and podcast artists are looking to see how feasible it is to have more audio outputs and inputs.

As playback and recording requirements continue to rise, it is important to address these concerns at once.

You may need to start upgrading the system as you move from basic stereo to better surround work.

This will require you to get six outputs instead of the basic two.

Or, you may need to get half a dozen microphone inputs for the live band on stage so that you can work with multi-track possibilities.

Whatever the reason for your increased need for multiple audio interfaces, you should know how to properly connect them all, or else it won’t work.

You will need a new audio interface with all the necessary features that you can use.

However, getting an expensive audio interface with multiple outlets is expensive.

Plus, abandoning your old one which won’t sell for a lot of money either can be hard.

This is why you need to realize that you can buy an identical second interface and double up on the features too.

You will need to get written drivers that are specially designed to recognize multiple audio interfaces.

Standard drivers that are designed to support single devices may not be equipped to work on multiple audio interfaces.

They are unable to spot the difference between the interfaces, which is why they may ignore them entirely. Your PC may even fail to boot it or crash too.

There are many manufacturers that you have created drivers that can support multiple drivers.

You will be able to use them for up to four identical audio interfaces or get models in the same range.

Do make sure to download the latest driver possible for the interface since that will give you more control over the audio quality.

It can be trickier to check whether the interface you are buying has a multi-device driver installed already.

You may need to check with the manufacturer or ask the store helpers for more information.

You should do this research before you make the purchase so that you don’t get stuck with a subpar device.

There are multiple audio interfaces that you can invest in which come with support for multiple devices.

The M-Audio Delta audio interface can be used for up to four devices for Windows, three for Mac OS X, and eight for Linux OSS.

You can successfully use up to four devices as well as other mixtures of small Delta interfaces without any issue.

The driver is also easy to install, so even newbies will not face any issues.

The MOTU audio interface driver is great for multi-device support. If you get the PCI424 card, you will be able to use it for up to 4 devices.

You can use it for a large range of audio options from HD 192 to 2408. The Maxio XD by ESI Pro is also a great option.

It can support up to four units and have a wide range of multi-device drivers to choose from.

If you want to install more outputs and inputs for your audio system, you need to choose interfaces that already have a driver for multiple devices.

This can make it easier for you to set up the system and ensure that audio quality is top-notch.

When you buy compatible interfaces, your streaming input and output levels will work better.


Multiple audio interfaces can be the best option for people who want high-quality sound.

Compromising the quality by using basic hardware is never a good idea for people who want to record music or podcasts.

Getting expensive recording equipment and then compromising it with subpar audio interfaces can ruin the entire experience for you.
