Should Microphone Level Be at 100?

Hey friend! Setting your microphone gain properly is one of the most important things you can do to get the best audio quality in your recordings. But you may be wondering – should I set my mic level to 100% maximum?

The short answer is no, 100% is usually too high and can actually cause issues. In this guide, I‘ll explain exactly why maxing out your mic gain is not ideal and how to find the optimal level for crystal clear sound.

What is Microphone Gain?

Let‘s start with the basics. The gain knob on your microphone, audio interface, or recording software controls the microphone gain – this is the amount of amplification applied to the signal from the mic before it gets recorded.

Gain determines how sensitive your mic is – cranking it up makes the mic more sensitive to quiet sounds, while turning it down makes it less sensitive.

It‘s basically the input volume control for your microphone. Gain staging allows you to dial in the perfect balance between loud and quiet sounds.

Why You Should Avoid 100% Gain

Here are a few key reasons why I don‘t recommend setting your microphone gain to the maximum level:

1. Distortion from Clipping

Too much gain overload the mic signal, causing the tops and bottoms of the audio waves to get "clipped" off. This clipping distortion sounds absolutely terrible – crunchy and digital.

There‘s no way to fix it after the fact. Once your sound wave gets clipped during recording, that information is lost for good.

2. Increased Background Noise

Higher gain means the mic is more sensitive. This also picks up more of the inherent noise in your signal chain – things like preamp noise, room tone, computer fans, air conditioners, etc.

The higher the gain, the worse your signal to noise ratio. Clean audio relies on maximizing the volume of the signal you want (your voice) while minimizing the unwanted noise.

3. Lack of Headroom

Headroom refers to the difference between the peak signal level and the maximum before clipping. More headroom gives you margin for dynamic variances – when you suddenly sing a loud note or make a sharp laugh, for instance.

If your gain is already maxed out, you have no headroom left. So any transient spikes in volume will smash into that ceiling and clip. Leaving some extra headroom in your gain structure prevents clipping.

4. Inflexibility in Post Production

One last disadvantage of maxing your gain during recording is that you lose flexibility when it comes time to edit and mix.

If your loudest peaks are already hitting the ceiling, you have no way to boost the level of quiet sections without clipping the loud parts.

Leaving some gain in reserve allows you to tweak levels later as needed to balance the vocals or instruments.

What‘s the Optimal Microphone Gain Setting?

So where should you put your gain? 100% is too high, but you also want a strong signal. Here‘s my recommendation:

For vocals and acoustic instruments, set the gain so your loudest singing/playing peaks around -12 dB on the recording meter.

This leaves you a full 12 decibels of headroom above your loudest signals, preventing clipping while keeping the signal strong.

The optimal gain range for most recordings falls around 60-80% of your interface or mic‘s maximum gain limit. But every signal chain is a bit different, so you have to test and tweak.

Listen critically to find the right balance between the strongest signal before peaking. Some trial and error is required to get it just right!

A Real World Example

Let me walk through a real example of setting gain for a vocal recording session:

1. First, I‘ll connect my trusty Shure SM58 microphone to my Focusrite Scarlett 2i2 audio interface.

2. In my DAW, I‘ll create a new mic track assigned to Input 1 of my interface where the SM58 is connected. I‘ll enable input monitoring so I can hear the mic signal.

3. Next, I‘ll have the vocalist perform a simple mic check. I‘ll ask them to sing a bit of the song at about the same volume they plan to record.

4. As they sing, I‘ll carefully turn up the gain knob on my interface while watching the input meter in the DAW. I‘ll stop when the loudest peaks land around -12 dB on the meter.

5. I may tweak the gain up or down a hair to get it just right. I‘ll record some trial takes and examine them in my DAW to make sure there‘s no clipping or excessive noise.

6. When I have the gain dialed in nicely, I‘m ready hit record and capture the final vocal tracks!

Proper gain structure takes a bit of practice, but it‘s a skill that will instantly take your recordings to the next level.

Gain vs. Output Levels

One important distinction when setting levels is the input gain coming into your interface vs. the output volume you hear in your headphones.

Gain controls the sensitivity of the microphone and comes before your DAW.

Output level controls how loud you hear the playback signal and comes after.

You can turn up the output volume without any clipping. The key is setting your gain properly to capture a strong signal without clipping or distortion.

Some folks make the mistake of recording with low gain and just cranking the output level. This can degrade your signal quality compared to optimal gain staging.

Gain Staging for Smartphones and Mobile Recording

On smartphones and tablets, the mic gain is typically set automatically by the device. You don‘t have a dedicated gain knob.

But you can still actively control the input levels using mic positioning. Get closer to the mic for louder sounds or move further for quieter pick-up.

Watch your recording app‘s levels and aim for peaks around -12 dB. If the mic is still too quiet even close up, consider using an external preamp or mic with manual gain control.

Common Microphone Gain Problems and Solutions

Here are some typical problems you may run into with microphone gain and volume levels, along with fixes:

Problem: Signal is clipping and distorting

Solution: Turn down the gain at the source until clipping stops.

Problem: Too much background noise in recordings

Solution: Reduce gain slightly and treat acoustic problems in your recording space.

Problem: Voice is too quiet even near the mic

Solution: Increase gain at the interface/mic until your vocals peak appropriately.

Problem: Inconsistent levels when musician moves around

Solution: Maintain consistent positioning and performance. Use compression to help tame dynamics.

Problem: Crackling, popping, or distortion

Solution: Could indicate an issue with the mic or cable. Try another mic cable first.

The Best Budget Microphones Under $100

You definitely don‘t need to spend mega bucks to get pro-quality sound. Here are some of my favorite mics for under $100:

Audio-Technica AT2020 – An affordable staple in home studios. Great for vocals, acoustic guitar, piano, and more.

Behringer XM8500 – Nice and warm vocal mic with shock mount. Impressive value.

Blue Snowball Ice – Plug and play USB mic perfect for podcasts, voice overs, Twitch streaming, or instruments.

AKG P120 – Studio quality condenser mic with switchable polar patterns for $99.

Shure PG58 – Rugged live performance mic specially designed to handle loud volumes without feedback.

Sennheiser e835 – Dynamic cardioid mic optimized for live vocals. Crisp sound with excellent feedback rejection.

Really any of these mics can capture pro-quality audio when set up properly. Of course, spending more gets you improved build quality, specs, and components. But skills matter more than gear!

Should You Buy an Expensive Microphone?

In my experience, mic quality has diminishing returns after you get past the really cheap models. For example:

• A $50 microphone will sound drastically better than a $10 mic.

• A $500 mic will be noticeably better in detail and clarity than a $100 mic.

• But a $1000 mic won‘t capture drastically better audio than a $500 model, assuming they are both quality mics.

You hear huge jumps at the low end, but less difference once you hit professional gear. Focus on dialing in the gear you have rather than chasing expensive upgrades.

Conclusion

Thanks for sticking with me on this microphone gain guide! The key takeaways:

• Set your vocal mic gain so peaks land around -12 dB for optimal levels without clipping

• 100% gain is usually too hot – leave some headroom for dynamics

• Finding the right gain balance requires trial and error – test record!

• Output level for monitoring is different from input gain staging

• Budget mics can sound just as good as expensive ones with proper skills

I hope these mic tips help capture incredible audio in your next recording session. Feel free to hit me up with any audio questions! I‘m always happy to nerd out on gear.
