Is An Audio Interface Necessary For A Home Studio?

Having the right gear for your home studio is an absolute necessity.

Music production is so computer based nowadays which makes it important to understand software as much as hardware.

Audio Interfaces are optimized for maximum quality audio production, they also act as high quality external sound cards that have outputs for microphones and instruments, which makes them very necessary devices in any recording studio.

Therefore, if you want to record and produce professional standard music, an audio interface is absolutely necessary for your home studio. But you can still produce music without it.

Technically, an audio interface is not necessary for a home studio. You’ll do just fine with your computer’s built-in sound card. However, you may run into issues of latency and unless your computer has inputs and outputs for certain equipment. You’ll have nowhere to hook it into.

This is one of the reasons why most audiophiles will advise you to use an audio interface, even for a simple home studio.

Many producers out there usually have to decide whether they should simply go on to buy a USB microphone, hook it up to their computer and start recording or not.

So, what’s more important, a microphone or audio interface? FIND OUT HERE.

What is an Audio Interface?

An audio interface is a device whose role is to convert analog signals to digital signals and convert digital signals back to analog signals.

It records analog signals like vocals and then converts them to a digital signal that your computer is able to understand and interpret through the use of a Digital Audio Workstation.

When you playback the audio using your computer,the sound you hear through your speakers is an analog signal which is a result of the audio interface converting the digital signal to analog on playback.

Benefits of using an audio interface

  • Improves the overall sound quality of audio signals.
  • Reduces latency (LEARN WHAT IS CONSIDERED GOOD LATENCY)
  • Allows you to plug in microphones, instruments and studio monitors.
  • Allows you to record music optimally like the expert producers do, which changes the dynamics of your work.

Your dedicated consumer sound card that comes with your computer is able to produce good quality audio but the internal components of audio interfaces give them superiority quality-wise.

Does an audio interface improve sound quality?

This is really a popular question in the producer community.

When audio signals are sent through an audio interface the playback quality of the resulting signal will be of higher quality and less noisy.

Audio interfaces having better optimized internal converters makes this possible.

This is the primary reason why I recommend using an audio interface in in situation that calls for music production.

The converters that come with audio interfaces will convert audio signals a lot more accurately as compared to the degree to which an in-built consumer sound card will convert the same signals.

When you’re not using an audio interface, the audio signals will be processed with your computer’s decent standard built in sound card, which is not a bad thing entirely.

However if you’re recording and producing music with a computer, an audio interface will be a better choice if you want your music to sound PROFESSIONAL.

Great sound quality in recording largely depends on the ability of your sound card (whether internal or external) to output audio signals as perfectly and accurately as they are recorded and captured by your microphone.

This is one of the reasons why an audio interface is always a handy tool to have in your arsenal.

Input and Output connectors

Most audio Interfaces allow you to plug in microphones, musica; instruments, studio monitors.

If you’re looking to record an instrument or use it inside a DAW, an audio interface is your best bet.

Most professional record producers use audio Interfaces in their recording process in order to achieve cleaner recordings ready for mixing and mastering.

The beauty is that you can connect most audio Interfaces directly to your computer via USB ports or PCMCIA slots.

As a person that takes their craft seriously, I can definitely say that an audio interface is an item every music producer should have whether you are producing from home or not.

Applications of Audio Interfaces

Vocals

Most audio Interfaces have Inputs that allow you to plug in one or more microphones that require an XLR connection to record vocals, most computers don’t have XLR connection ports.

Furthermore, In any case that you have multiple vocalists or have a band ready to record, or a couple of friends that want to record a podcast, the right interface will allow you to connect more than one microphone and be able to use them all at once.

Instruments

You can’t directly plug in most instruments into your computer therefore an audio interface can act as the bridge between your instruments and your computer.

Multiple outputs are very useful, for example most dj’s want to be able to be to set up separate headphone mixes or send audio elsewhere for some more processing, audio interfaces make this possible.

Speakers

Studio monitors are the preferred speakers for most when it comes to producing music because they output an accurate representation of sound that allows engineers to judge the sound more objectively.

When plugged into an audio interface, Studio monitors work really well.

Latency

In audio processing, latency is a time delay usually in milliseconds that occurs when an audio signal is sent into your computer system and when it emerges as audible sound.

An audio interface accompanied with good audio drivers, the right settings and converters on your computer will reduce latency to a degree, but this may vary case by case depending on things like, analog to digital/digital to analog conversion, digital signal processing, buffering, transmission time and the audio speed in the transmission medium.

Some audio interface manufacturers make interfaces that have what is called Direct Monitoring or Zero Latency Monitoring.

Essentially, Direct Monitoring or Zero Latency Monitoring is the ability to be able to monitor an input signal directly from the audio interface before it goes to your DAW; it allows a person to listen to the input signal immediately with almost zero latency which is great if you are performing live or playing an instrument.

Most DAWs have embraced and implemented Direct Monitoring technology into their software which makes it really easier and more pleasant to use an audio interface as opposed to your built in sound card.

Some interfaces may not have Zero Latency monitoring, so it is important that you check the product specifications of the interface before you consider purchasing it.

If it should so happen that you have an audio interface that doesn’t come with Zero Latency already, you can use these tips to try and minimize latency:

  • Reduce the buffer size in your DAW
  • Raise the sample rate, the higher the sample rates the lower the latency. Keep in mind that increasing the sample rate will also mean additional stress on the CPU
  • Disable the Audio Input device if you’re not recording from external sources.
  • Use ASIO or ASIO4ALL audio drivers on Windows
  • Turn off and don’t use your Bluetooth or Wi-Fi, because streaming audio wirelessly will increase the latency value.

Phantom Power

In the context of music production, phantom power is the electric power transmitted through microphone cables that is required in order to operate a microphone.

Most studio condenser microphones require a power source to be able to work hence it is this power that is referred to as phantom power.

It is called phantom power because it works by transmitting power using the same cable that is carrying the audio signal into the system, so it is able to provide simultaneous transmission of both the audio signal and the power to the microphone or audio device using the same single cable.

Most studio microphones run on 48 volts of phantom power. Usually an audio interface will come with enough voltage of phantom power to supply to a microphone.

The most common audio interfaces will typically supply voltage within the range of 11 to 52 volts and will be present on a balanced XLR Connector; however some microphones will only require 9 volts of power but most professional recording microphones will require more than that.

It is wise to check the product specifications, voltage to be exact, of a microphone before directly hooking it into an audio interface in order ensure that your phantom power supply is compatible.

There are microphones available on the market that have internal batteries and some that don’t, it is advisable to remove these batteries if you want to connect the microphone to an audio interface for phantom power.

You may wonder if phantom is going to affect the quality of the sound since the cable delivering the voltage is also carrying the audio signal.

Well the answer is no, phantom power will not affect sound.

However keep in mind that only a microphone compatible with phantom power should be hooked into an audio interface XLR connector supplying DC power to a microphone to avoid any incompatibility issues.
