You found out what mic your favorite streamer uses. You bought the same one. You plugged it in, started talking, and... it sounds nothing like theirs. Flat, noisy, maybe a little harsh. What went wrong?
Nothing, actually. That's just what a raw microphone sounds like. The polished, broadcast-quality voice you hear from your favorite creators isn't coming from the mic alone. It's coming from how their audio is processed after it leaves the mic. The good news is that those same improvements are available to you, and most of them are free.
Before any software comes into play, three free fixes make the biggest difference with any mic.
Gain controls how sensitive your mic is. Too low and your voice is quiet (boosting it later also boosts noise). Too high and you distort when you get loud. Aim for the middle, where your normal speaking voice hits a healthy level without peaking.
Where you sit relative to your mic matters more than people realize. About 6 to 10 inches from your mouth, slightly off-axis, is a good starting point. Too far sounds distant and noisy. Too close causes bass buildup and harsh plosives.
Your environment colors your sound more than you'd expect. Hard surfaces reflect audio back into the mic, creating a hollow quality. You don't need professional treatment, but even a rug, curtains, or a bookshelf behind you can help.
Once you've dialed these in, do a quick test recording in something like OBS Studio or Audacity. Record 30 seconds, play it back, and listen for background noise and inconsistent volume. This gives you a baseline to compare against as you add effects.
Audio effects process your mic signal in real time, shaping your voice before it reaches your stream, recording, or call. Elgato offers free versions of each core effect on Elgato Marketplace, and they all run inside Wave Link, a free audio mixing app that works with any microphone. Just download Wave Link, grab the effects, and they install with a couple of clicks.
Here's what each one does.
That background hum, fan noise, and subtle hiss in your test recording? Your ears tune it out, but your mic doesn't. Noise removal uses AI to separate your voice from everything else in real time. The before-and-after difference is immediately obvious.
Elgato Noise Removal is free on Marketplace and works on both Windows and macOS. It's lightweight enough to run on any CPU, and you can apply it to multiple channels at once, like cleaning up a friend's noisy mic in voice chat.
Every mic and room colors your voice differently. An equalizer lets you correct for that by adjusting specific frequency ranges. Cut low-end rumble from desk vibrations, reduce muddiness in the low-mids, or add a subtle boost in the upper range for more clarity. Small adjustments, usually just a few decibels, but they add up fast.
Elgato Equalizer is free on Marketplace. Frequency ranges have plain-language labels instead of just numbers, there's a built-in animated tutorial, and you can see your voice's frequency response in real time. It supports up to 8 customizable bands along with high-pass, low-pass, and shelf filters. Marketplace also has community-made EQ presets for different mic types and use cases if you don't want to start from scratch.
Words with "S," "SH," and "CH" can come through as sharp, piercing bursts, especially on condenser mics. This is called sibilance, and it's one of the most common listener complaints even when everything else sounds great. A de-esser targets those specific high-frequency sounds and gently reduces them so they sit naturally in your voice.
Elgato De-Esser is free on Marketplace. Just speak and it automatically detects the right settings for your voice. Pro settings for release and ratio are available if you want more control, but they're entirely optional.
When you talk naturally, your volume fluctuates constantly. You lean back, get excited, trail off. Without processing, your listeners are stuck adjusting their volume to keep up. A compressor narrows that dynamic range automatically, bringing quieter parts up and keeping louder parts in check so your voice stays at a consistent level.
Elgato Compressor is free on Marketplace for both Windows and macOS. It uses a simple threshold slider and real-time waveform visualization so you can see and hear the effect as you adjust it.
The order you stack these effects matters. A good starting point: Noise Removal first (clean the signal), then EQ (shape the tone), then De-Esser (tame sibilance), then Compressor (even out dynamics). This follows a general principle that works well for most setups: remove what you don't want first, then shape and control what's left.
Wave Link does more than just run effects. You can create up to five separate mixes, each with their own volume levels and effect chains, so your stream, headphones, and recordings can all sound different simultaneously. It supports VST3 plugins on Windows and AU on macOS, so third-party effects work too. And if you're using a Stream Deck, you can control everything from there without leaving your workflow.

Everything above works with any mic through Wave Link. But if you want to take things further, Elgato Wave devices add a layer of processing that happens directly on the hardware itself, powered by Wave FX Processor.
With Wave FX Processor, a suite of onboard DSP effects runs directly on the hardware with zero latency and no CPU load. Your fully processed voice arrives natively in every application without virtual routing or workarounds. On top of that, Clipguard 2.0 makes clipping virtually impossible, Auto Gain sets your levels in seconds, and VST Insert technology lets your Wave Link plugins integrate directly into the hardware signal chain for lower monitoring latency than software-only setups.
Wave FX Processor is available in Wave:3 MK.2, Wave XLR MK.2, XLR Dock MK.2, and Wave XLR Pro. To compare devices and explore what each one offers, check out our Wave audio overview.
Start with the basics: get your gain and positioning right. Grab the free effects from Elgato Marketplace and load them into Wave Link. Even one or two effects can make a meaningful difference, and you don't need to get everything perfect on day one.
