How do I record with a USB microphone?
A USB microphone is an external microphone that connects to a computer via USB cable instead of the regular 3.5mm audio jack. USB mics provide much higher sound quality compared to built-in laptop mics or headsets, making them a popular choice for podcasting, game streaming, vlogging, voice over work and other recording applications.
The main benefits of using a USB mic over a built-in one are:
- Greatly improved audio quality – USB mics use high quality components and converters, resulting in clear, full-bodied sound.
- Flexibility – USB mics can be positioned optimally to suit different recording scenarios.
- Plug and play connectivity – USB mics connect instantly to a computer without needing extra drivers or interfaces.
- Affordability – Quality USB mics are available at reasonable prices compared to pro studio mics.
So for anyone looking to elevate their audio recordings above basic built-in mic quality, a USB microphone is the simplest and most cost-effective option.
Choosing a USB Microphone
When choosing a USB microphone, you’ll first need to decide between a condenser or dynamic microphone. Condenser mics are more sensitive and better suited for recording vocals and acoustic instruments in a controlled studio environment. Dynamic mics are less sensitive but more durable, making them a good choice for live performances or podcasting where there may be more background noise.https://www.soundguys.com/best-usb-microphone-7977/
If you plan to use the mic primarily for studio recording, a condenser model like the Blue Yeti X is a great option. For podcasting or live streaming, consider a dynamic USB mic such as the Shure MV7 or Samson Go Mic, which will help reject unwanted ambient noise.https://www.nytimes.com/wirecutter/reviews/the-best-usb-microphone/
There are also budget-friendly USB mics like the Amazon Basics Desktop Mini Condenser Mic which can provide decent recording quality at a fraction of the cost. Just keep in mind that cheaper models may lack some of the premium features and sound isolation of pricier mics.
Microphone Setup
Setting up a USB microphone properly is important for capturing high-quality audio. Here are some tips for getting your USB mic plugged in and positioned correctly:
Plugging In and Installing Drivers
First, plug your USB mic directly into your computer’s USB port. Avoid connecting through a USB hub which can sometimes cause interference.
Install any required drivers for the microphone if prompted by your operating system. Keep the drivers up-to-date to ensure proper functionality.
Positioning the Microphone
Place the microphone on a sturdy surface or stand, approximately 6-12 inches away from your mouth when seated. Make sure the mic is pointed directly at your mouth and the front of the mic (usually indicated by a logo) is facing towards you.
Avoid positioning the mic directly against your mouth, as this can lead to pops and distortion. Experiment with positioning to find the optimal distance for your voice.
Use a pop filter in front of the microphone to reduce plosives and mouth noises. Place the filter 1-2 inches away from the mic.
Position the mic slightly above your mouth, angled downwards, to take advantage of the proximity effect for a richer, warmer vocal tone.
Check the microphone settings to make sure the gain/volume is not set too high to avoid distortion.
Microphone Technique
Proper microphone technique is essential for getting the best sound quality when recording with a USB microphone. Here are some key tips:
Position yourself an appropriate distance from the microphone – generally 4 to 6 inches away for a condenser mic. Get too close and you may get popping sounds or audio distortion. Too far away and the audio will be faint and filled with room ambience.
Avoid plosives (popping “p” and “b” sounds) by speaking across the microphone at a slight angle rather than directly into it. Using a pop filter can also help reduce plosives.
Reduce sibilance (excessive “s” and “t” sounds) by again avoiding speaking directly into the mic capsule. Speak across at a slight angle instead. De-essing during editing can also tame sibilant sounds.
Maintain consistent distance and angle from the mic as you record. Even small movements can impact sound quality. Use a mic stand to keep the microphone fixed in position.
Minimize other sounds in your recording environment, especially computer fans or hard drive noises which the sensitive condenser mic will pick up.
With proper microphone technique, you can achieve clean, professional sounding recordings with your USB mic.
Microphone Features
USB microphones offer a variety of useful features to help you achieve the best sound quality for your recordings.
Gain Control
The gain control allows you to adjust the microphone’s sensitivity to incoming audio. Turning up the gain increases sensitivity, so quieter sounds are picked up. Turning down the gain decreases sensitivity for louder audio sources. Adjust the gain so your loudest moments are just below peaking/distorting.
Mute Button
A mute button allows you to quickly mute the microphone when needed. This is useful when you don’t want to record something like a cough or background noise. The mute button toggles the microphone’s audio on and off.
Headphone Jack
A headphone jack allows you to directly monitor the audio input from the microphone. Monitoring your mic input helps you make sure the gain is set properly and there are no issues like clipping. It also reduces latency, allowing you to hear your voice in real-time.
Recording Software
When recording with a USB microphone, you’ll need software on your computer to capture the audio input. There are many options available, but some of the most popular free programs for basic recording are:
Audacity – An open source, cross-platform audio recording and editing software. It has basic tools for recording, editing, mixing and exporting audio. Audacity is very versatile and works well for simple vocal and instrument recording.
Garageband – Apple’s digital audio workstation software included free with Mac computers. Garageband allows multi-take recording, adding effects, mixing tracks, and exporting finished recordings. It has a simple interface geared towards music creation.
OBS (Open Broadcaster Software) – A free and open source software for live streaming and screen recording. It can capture audio from USB microphones and is commonly used for broadcasting, podcasting, and video game streaming. OBS offers scene mixing, audio filters, and video capture capabilities.
For more advanced editing and mixing capabilities, closed-source paid options like Adobe Audition or Logic Pro provide professional tools for improving audio quality and polishing recordings. However, programs like Audacity, Garageband, and OBS cover the basic recording needs for most casual users of a USB microphone.
Mixing and Editing
After you finish recording with your USB microphone, it’s time to start mixing and editing the audio. This process allows you to improve the overall sound quality and polish your recordings. Here are some key steps to focus on:
Noise Removal
Even high-quality USB mics can pick up unwanted background noise like computer fans, HVAC systems, traffic outside, etc. Use a noise removal plugin like iZotope RX to strip out constant background noise and clutter.
Compression
A compressor plugin helps control the dynamics and loudness of your vocal track. Gentle compression can make the audio more consistent and polished. But be careful not to over-compress or you may lose clarity and detail.
EQ
An equalizer allows you to boost or attenuate frequencies in your recording. For example, a high-pass filter can remove rumbling low frequencies. Notch filters can eliminate resonances. And boosting certain frequencies can add clarity and brightness to a dull track. Apply EQ with a subtle hand for the most natural results.
Proper mixing and editing can take your basic USB microphone recordings to the next level. Invest time mastering these essential audio processing skills to get the most out of your productions.
Improving Sound Quality
There are a few simple ways to improve the sound quality of your USB microphone recordings. Acoustic treatment of your recording space can make a dramatic difference. Adding sound dampening materials like acoustic foam panels or blankets on the walls will reduce room reverberation and echo. Placing the microphone closer to the sound source while recording will also minimize the capturing of room ambience.
Using a pop filter is also highly recommended for vocal recordings. Pop filters are screens that go in front of the microphone to reduce plosive sounds like “p” and “b” that can create unwanted popping noises. According to a Reddit thread, “A pop filter is a must have in my opinion. It helps clean up the audio and prevent pops from loud p’s and stuff.” Pop filters are inexpensive and widely available.
