What is an Audio Interface?

Audio interface is the hardware allows the user to record and playback audio from a computer. It is the part of studio equipment that enables to record analog and digital audio signals. Help to send the recorded audio signals them into the computer so that the post-processing work can be accomplished. It allows to connect things like microphones and guitar cables to a computer and record via USB. Basic recordings can be recorded with any modern computer, laptop or tablet. It recreate the recorded audio interface a more accurate representation of the sounds. Even audio interface is used for recording music and pod-casts, and in video post-production for recording songs and sound idea.

Inputs and outputs configuration of audio interface

Choosing the right input & output configuration. The first thing to consider when choosing the best audio interface  for home studio. The number and type of inputs and outputs you need depends entirely on what you want to be able to record, now and in the future.

For singer-songwriters who want to capture their voice and acoustic guitar using microphones, a pair of balanced mic inputs will be required. Condenser mic need an input with phantom power to energize it. To record in acoustic guitar in stereo with vocal, two inputs would be insufficient, and a four input interface would be required. Most audio interfaces include two or more microphone preamps.

For electric bass, guitar, or electronic keyboard that can connect directly to the recording setup, just need an instrument-level input, often referred to as a “high-Z input.”

Digital input output is needed for incredibly useful down the road. Some external devices with S/PDIF and ADAT connector allows connect multi-channel mic preamps to increase the amount of simultaneously available mic preamps in recording system.

Connectivity

It’s a  computer-related technology. Few audio interface connection types are considered standard. The most common connection types are – Thunderbolt, USB, FireWire, and PCIe.

Thunderbolt

It’s new reference standard for connecting audio interfaces. The brand name of a hardware interface developed by Intel. This high-bandwidth Intel technology is currently installed on the newest Mac computers. Thunderbolt 3 is 8 times faster than USB 3.

USB

USB or Universal Serial Bus is a plug and play interface. Audio interfaces typically run over USB. This is the most common connectivity option. Best for mobile recording with the help of laptop.

Firewire

It is a method of transferring information between digital devices. It transfer audio and data at more consistent rate than USB but fewer interfaces uses this connectivity option.

PCIe

PCIe or PCI Express is an internal card-based computer connection platform. It connection provides high data bandwidth and low latency.

Level of sound quality

Here we will discuss over the key factors and specs that influence overall audio quality of recording-

Bit depth

Digital recording converts the analog audio into bits and bytes. In simple words, greater the number of bits the higher the level of fidelity. Fidelity is depend on the digital bitstream describes musician’s vastness dynamics while deducting noise. The audio CD uses a 16-bit standard that delivers a dynamic range of 96dB.

Sample rate

Sample rates is the digital snapshots of audio gear captures from time to time. Higher sampling rates capture information that contributes to overall fidelity. It can create more perfect music. work at 48kHz, 96kHz, or even 192kHz sampling rates.

Converter quality

Analog to digital, and digital to analog  converters are the devices that convert the incoming analog audio signals into digital data, and the digital data from the computer back into analog audio output signals.

Types Of Audio Interfaces

There are numerous types of Audio Interfaces are available in the current market 2020. We will put into your view 5 top of them –
