Best Audio Interfaces for Live Streaming & Podcasting

It’s very important to deliver quality content when you stream or podcast. It won’t be successful without this component. Therefore, it’s necessary to have high-quality equipment to deliver the best streaming audio. Let us look what exactly is required for streaming to attract the audience and perform better than other streamers or podcasters. It would be great to use a professional dynamic or condenser microphone. The second option is more preferable. The performer should have a floor or a table microphone stand. Audio gear should include good full-range headphones or active speakers with the right tone transmission (active monitors). And the last but not least important thing is the internal soundcard, miniature mixing console or external USB/Firewire sound interface for connecting a microphone and subsequent recording. The choice of interface depends on the type of recording device. A condenser typically requires +48 V phantom power. So, as you see there is much to explore in this issue. We will cover just one of the items in this article – choice of the best audio interface for streaming. It can be a rather complicated question for non-savvy consumers as there are so many interfaces of different kinds on the market, but if you want excellent sound in your streams, the question is worth exploring.

Why do customers want to buy an audio interface?

Any streamer wants to perform well, especially, when the person earns his living on it. It seems that there is enough to have a computer and some software program like Cubase, Reaper, Sonar or some other. After all, there is in-built audio card in it. Why is an audio interface needed then? Let us look how external audio interface differs from the in-built audio card. Apart from headphone jack, the embedded audio card usually has 1 stereo in and 1 stereo out. This is not a pro-level quality and it tells upon the result. Besides, connectivity problems arise. Consumers don’t have problems with USB but it’s impossible to use XLR connection then. Buying an audio interface for streaming, one can solve all problems. Best quality is guaranteed then. You will have to buy an audio interface for your activity if you want to get the best audio. There are different connectivity alternatives for users of interface, while the process of conversion delivers excellent sound without noise and latency.

What features to look for in an interface?

It was not a big problem before. One could just insert the interface into a PCI slot or Firewire connection. The other gear with lots of ins and outs was incredibly expensive, so folks definitely knew what to choose as they couldn’t afford professional equipment. Now it’s all different. Many people who do not work in the sphere of sound can purchase audio interface for streaming audio, podcasting or just for fun. The price even for best audio equipment is reasonable, while the quality of sound increases considerably.  The audio interface is provided with all necessary features, provided with excellent connectivity, USB and low latency so the person doesn’t have any technical issues when he needs interface for streaming or some other activity. So, what should one pay attention to when making a choice?

  • Quality of converters.
  • Low latency.
  • The number of inputs and outputs.

It’s important what you want to record. For drum kit, for instance, you need more inputs than mics. When you play the guitar and sing to it, you record two sources simultaneously. There can be different situations and you need to look what you are going to record.

Type of inputs explained

An audio interface can include XLR input and ¼’’ jack. The combination of inputs in one port is applied for smart design. It helps to save space in the devices, but at the same time it’s possible to use only one of them at a time and simultaneous use is impossible.

¼’’ jack is needed for connection of instruments but one can use it with streaming and podcast devices. It’s possible, for instance, connect the wireless lav mic that feature ¼’’male ends.

The XLR port is needed to connect the mics. They are of standard size that is used internationally therefore there is no need to worry about the suitability of the cable.

Type of outputs explained

The following types of outs are found in devices. Line out is the main one enabling connection to interface. ¼” jacks are used to connect the device to the left and right speakers. The volume knob located on the interface controls the output.

The other popular type of output is Thunderbolt port. It enables incredibly fast transfer speed and a low level of latency. Now Thunderbolt 3 version is used that is two times faster than Thunderbolt 2. In order to understand its efficacy, you should know that its speed is 8 times faster than USB3. Many modern Macs are supplied with it to be able to support high-end audio interface.

Firewire is a type of output delivering more consistent data in comparison with USB. It is known for its reliability but it is seldom accessible for users.

The widespread type of output is USB. There are three versions of this connection that varies depending upon the bandwidth. The benefit of this output is that it uses USB buss power that is used for phantom power.

PCIe or Peripheral Component Interconnect Express is a type of output in computers. It makes the audio interface an internal component of computer. It is connected to the motherboard via PCIe port.

Important features

There are some other essential characteristics that were not regarded above but still, they matter when you select the best audio interface. It refers to phantom power that is needed for connection of condensers. It may not be so important for streaming and podcasting but it comes with almost every audio interface. It’s not recommended to use the phantom power with ribbon mics known for its fragility. These microphones can be damaged then. Dynamic microphones can be used either with phantom power or without it.

The other important feature is direct audio monitoring that gives the capability to hear the sound coming via the audio interface input almost without latency. ¼’’ female jacks are made as to the interface ports. Sometimes 3.5mm jacks are used.

There are headphones that are equipped with 3.5mm male end and come with ¼’’ adapter giving the possibility to use it for any audio interface.
