Audio Interface – Enables Your PC to Record & Playback Audio!

Audio Interface means a professional soundcard! It enables your Computer to record & playback audio. You will need it if you want to do serious audio work on your computer.

Want to do professional level audio work on your Computer?

Want an interface for all your input and output audio / midi connections?

Want low latency sound recording and playback?

Want great sound recording and playback quality?

If you want to do most of your recording on your computer, then having a professional soundcard (Audio Interface) is an absolute must, as the quality of the sound produced is based on this important piece of hardware.

But before we proceed further into the details, a brief description of what a soundcard is and how it fits inside your computer.

It sits inside the computer in a PCI slot and you connect all the cables at the back of this card.

Professional soundcards, also known as Audio interfaces, on the other hand has a box that sits outside the PC and a cable that is connected to the PC, either to the PCI card or to the USB/Firewire slot depending on the type of the interface.

The breakout box contains slots for all the input and output audio/midi connections.

The better the quality of these two things, the better the sound is going to be. These are one of the important reasons because of which the professional soundcards cost more than consumer soundcards.

Drivers are the software components that allow audio computer programs to talk to your soundcard; they come along with the card.

The drivers basically manage the traffic of data between the CPU, DAC and the audio application as and when it is needed.

DACs are converters that are physically present on the soundcard. The converters job is to read the incoming analog waveform and transform it into digital data. This important process is known as sampling and it determines the quality of your recorded sound.

Once the digital data is on your computer, it is very easy to manipulate it in different ways and store it on your computer.

Some of the limitations of a consumer sound card include:

• High latency (delay in the reproduction of sound, between initiating a sound and hearing it)
• General sound quality is not great
• Low sampling rates (recording quality is poor)
• The drivers may not work with most of the audio recording software applications
• No MIDI port. You cannot connect external keyboards/synths
• It is intended for home and office entertainment use. The emphasis is more on playback and casual use

• Low latency sound recording and playback
• Usually follows the ASIO protocol (suited for sound engineering and music software)
• Comes as external rack-mountable units which can be connected using USB 2.0/Firewire
• Large number of input and output connectors
• Hardware support for multiple input and output sound channels
• Higher sampling rates compared to a consumer soundcard
• Multi-channel data recording and real-time audio mixer and processor

You will have to make sure that the soundcard has inputs/outputs to connect to most of your gear.

In general, the following are some of the instruments that you will need to connect to your soundcard.

• Microphones
• Control surface (if you don't have a mixer)
• Audio speakers (AKA monitors)

You may also need external Preamps to raise the level of your mic's. Though most of the soundcards have built-in preamps, only the more expensive ones have really good preamps.

Besides the above mentioned gear, most of the other things like compressors, gates, Reverb and other special effects can be used as software in your Computer. So you do not need connections for these.

This is actually a tricky area since the drivers behave differently on different machines. Even if it works, you may have to download a different set of drivers whenever a new operating system is launched.

Just make sure that the soundcard you wish to buy has the following:

Out of these, only the PCI interface goes inside the computer, into the PCI slot. All the earlier soundcards used to be available only in this type and these soundcards can only be used with desktops.

The other interfaces are external in the sense that the main box stays outside and a cable connects the box to the computer.

Of all the external interfaces, the firewire interfaces are getting good reviews and are known to give good performances. It gets connected to the firewire port and can be used with laptops as well as desktop. They are very easy to connect and they also give you the option of portability.

With an overview of what things to look for in an Audio Interface, I think you should be able to find an Audio Interface that suits your needs the best.
