How can I record better quality audio?

High quality audio is extremely important for recordings. The audio quality can make or break the listening experience, regardless of whether it’s a music track, podcast episode, audiobook, or video. Poor audio quality can be distracting and make it difficult to understand the content. On the other hand, professional-grade audio allows listeners to fully immerse themselves in the recording.

There are several key factors that affect audio quality:

  • The recording environment – A quiet, soundproofed space is ideal.
  • Microphone quality – Condenser mics and other professional gear capture better sound.
  • Microphone technique – Proper positioning relative to sound source.
  • Preamps and audio interfaces – Quality gear prevents distortion and noise.
  • Recording settings – Sample rate, bit depth, number of channels.
  • Editing and processing – Equalization, compression, noise reduction.

Paying attention to each of these elements results in clear, detailed audio that effectively conveys the intended message and emotion.

Record in a Quiet Space

One of the most important things you can do to improve your audio quality is to record in a quiet space without background noise. Ambient sounds like traffic, people talking, appliances, air conditioning, and fans can easily get picked up by your microphone and make your recordings sound unprofessional.

Find a room in your home or office that is as isolated as possible from outside noises. Close any windows and doors to minimize sound from outside. Turn off things like fans, AC units, televisions, radios, and computers when recording. The quieter you can make the room, the better.

If you don’t have access to a completely noise-free space, try recording in a closet or under blankets to dampen the ambient noise. The goal is to capture the cleanest audio signal possible without interference from your environment.

Use a Pop Filter

A pop filter is an essential accessory for quality vocal recordings. As the name suggests, it helps prevent plosives (‘popping’ sounds) that can overload the microphone when singing or speaking. According to AudioMentor, a pop filter has two key purposes:

  • Eliminate popping noises
  • Protect the mic from moisture damage

When recording vocals, plosives can create a harsh ‘popping’ sound that distorts the audio. A pop filter creates a physical barrier to diffuse these blasts of air before they reach the microphone. This results in a smoother, more professional vocal recording.

There are many affordable pop filter options to choose from. You can also make a DIY pop filter at home using materials like pantyhose and a coat hanger. The key is to have a layer or two of mesh that allows sound to pass through while dispersing air pressure. Position your pop filter 6-12 inches away from the mic for optimal results.

Get a Quality Microphone

When it comes to recording high quality audio, the microphone you use is one of the most important factors. Investing in a good quality microphone designed for recording vocals or instruments can make a huge difference compared to using cheap mics or built-in computer mics.

There are two main types of microphones to consider – condenser and dynamic. Condenser mics are more sensitive and tend to capture more detail and nuance. They work well for vocals, acoustic instruments, pianos, and percussion. However, condensers also pick up more background noise. Dynamic mics are more rugged and better at rejecting off-axis sounds. They are ideal for recording electric guitars, amplifiers, drums, and live performances. When selecting a mic, consider the frequency response – a wider and flatter frequency range will sound more natural. Also look at the polar pattern, which determines how sensitive the mic is to sounds from different angles.

For home studios and beginners, large diaphragm condenser microphones like the Rode NT1-A (https://www.musicradar.com/news/the-best-microphones-for-recording) or Shure SM7B (https://www.reddit.com/r/musicproduction/comments/xamnin/a_good_recording_microphone_for_starters/) are excellent choices that won’t break the bank. Other top options are the Neumann TLM 102 for vocals and strings or the Shure SM57/58 for amplified instruments. No matter your budget, investing in the best mic you can afford will enable you to capture professional quality recordings.

Use a Shock Mount

A shock mount is an important accessory to consider when setting up a microphone for quality audio recording. According to Lewitt Audio, a shock mount isolates the microphone from vibrations that can cause rumbling noises in your recordings. Shock mounts attach to a microphone stand or boom arm, suspending the microphone within the mount to absorb shocks and vibrations.

Shock mounts help prevent sounds caused by bumps to your mic stand or surface vibrations from transferring to the microphone. This safeguards your audio from unwanted rumbling noises that can muffle or distort your recording. By isolating the microphone, a shock mount enables you to capture clean, crisp audio without interference from vibrations or shocks.

Choosing a proper shock mount for your particular microphone is important. The mount should securely hold the mic but also allow it to remain suspended and isolated. High-quality shock mounts tailored for specific mics will provide optimal vibration dampening.

Record at the Right Distance

The distance between your mouth and the microphone makes a big difference in the sound quality of your recording. Recording too close can lead to pops and sibilance, while being too far away results in a thin, distant sound.

For condenser microphones, a distance of 6-12 inches is ideal for vocals and voiceovers. Dynamic microphones can be positioned closer to the mouth at 3-6 inches. For a consistent sound, use a mic stand and pop filter to fix the distance.

To avoid pops and plosives, keep minimum distance of 4 inches for close miking. Angle the microphone just off center from your mouth rather than directly in front. Low cut filters and pop shields also help reduce plosives.

When recording, monitor your audio to ensure your voice is loud and clear without any distortion. Adjust the mic position gradually until you find the optimal distance and angle.

Set the Right Gain Level

Setting the correct gain level is crucial for getting a clean audio recording without clipping or noise issues. The gain controls the volume of the signal coming into your microphone or recording device. You want the levels high enough to get a strong signal, but not so high that it clips or distorts. The ideal peak level range to aim for is around -12 to -6 dB, which leaves enough headroom in case there are sudden volume spikes.

As a rule of thumb, your recording device’s meter should average around -20 dB to -10 dB, with the loudest peaks hitting no higher than -6 dB. Going above this risks clipping, which causes harsh digital distortion. It’s better to have a slightly lower input level that can be boosted later. Quieter audio with less noise is preferable to a distorted signal.

To set your levels properly, have the mic in position and ask your speaker to do a soundcheck at the same volume as the final recording. Adjust the gain knob while they speak so the meters reach an optimal range. Allow for some extra headroom as a buffer. You may need to tweak levels further once recording starts, so keep an eye on the meters. With experience, you’ll develop an intuitive sense for gain staging. But taking the time to set levels well is one of the most vital steps for quality recordings.

According to acoustic experts, “Between -20 RMS to -24RMS is a good starting point for a raw recording. You typically don’t record at the final ‘volume’ that a mix is rendered at” (Source).

Monitor with Headphones

Wearing high-quality headphones while recording is essential for monitoring your audio and identifying any potential issues. Headphones provide a more accurate representation of sound compared to speakers. This helps you notice subtle issues like clipping, distortion, uneven levels between multiple mics, and background noise that speakers may not pick up.

Headphones also allow you to closely monitor your microphone technique in real time. You can hear clicks, pops, plosives, and other issues caused by improper mic technique. This makes it easier to make quick adjustments to prevent problems in the recording. Proper mic technique is critical for capturing clean, quality audio.

Additionally, headphones help isolate you from sounds in the room that could bleed into the mics like echos. This allows for a more controlled recording environment. Wearing headphones is a simple way to improve your monitoring and mic technique for higher quality recordings.

Use Proper Mic Technique

Using proper microphone technique is essential for capturing high quality vocals or instruments. Here are some key tips:

Maintain a consistent distance from the microphone – generally around 4-6 inches away depending on the mic. You don’t want to be too close that pops occur, but not too far that the audio is faint. Also, keep the microphone angle consistent, pointed directly at your mouth.

Use a microphone stand to hold the mic in place. Handheld mics are more prone to movement and inconsistent distance. With a stand, you can maintain the ideal distance and angle at all times. Make sure the stand is secure and stable.

Avoid covering the microphone grille with your hand, which can muffle the sound. Keep your hand around the body of the mic instead of grasping the head if needed. Additionally, use a pop filter to avoid plosives on p’s, b’s, and other letters.

Before recording, do a quick check to listen for any pops or unevenness in volume to ensure proper microphone technique. A little technique goes a long way for professional, clear audio! [1]

Edit and Process Audio

After you’ve recorded your audio, it’s important to edit and process it to improve the overall quality. Here are some key steps:

Noise Reduction

Use noise reduction software like Audacity to get rid of any background noise in your recording. This makes the vocals much cleaner.

Compression

Add compression to even out the volume and make the quiet parts louder and loud parts quieter. This results in consistent levels throughout.

EQ

Use equalization to boost or attenuate certain frequencies. For example, adding a high-shelf filter can make the vocals brighter and more present.

Repair Clicks/Pops

Look for any clicks, pops or imperfections and carefully remove them. This clears up any unwanted artifacts.

Normalize Levels

Finally, normalize the entire clip to bring up the overall volume to a common target level. This gives you a nicely polished end result!
