Gain Staging: How to Set Your Levels in FL Studio and Logic Pro

Your beat sounds fine, your vocal sounds fine, but once everything plays together it gets messy. Your compressor is squashing way too hard, your master meter is in the red and you can't tell where it goes wrong. Chances are your gain staging is off. It sounds technical, but the idea is simple: make sure every sound hits your plugins and your mixer at a healthy level. Here's what gain staging is, why it matters and how to do it in FL Studio and Logic Pro.

What is gain staging?

Gain staging means setting the level on purpose at every step of your signal chain. From your recording to your first plugin, to the next plugin, to your mixer track and finally to your master. Each step is a "stage". If the level is too hot somewhere, you get distortion or plugins that react differently than you want. If it's too low, you end up turning everything back up later.

So it's not about one knob. It's about the whole route your sound takes.

Why it matters, even in a modern DAW

You'll often hear: "You can't clip inside a DAW anyway." There's some truth to that. Image-Line's FL Studio manual says audio inside FL Studio is represented as (at least) 32-bit floating point numbers, and that it won't run out of headroom under any practical circumstance on a mixer track. So a peak over 0 dB on an insert isn't a disaster on its own. Gain staging still matters, for three reasons:

• Your plugins react to the level going in. A compressor with a threshold of -20 dB squashes a loud vocal much harder than a quiet one. A saturator sounds different when you drive it harder. Same settings, different level, different sound.
• Your master and your export can clip. The same manual calls the master track the usual output to the "physical world", so you don't want it peaking over 0 dB. Render to a fixed format like 16- or 24-bit and everything above 0 dB gets cut off. You can't get that back.
• Your mix stays easy to work with. When everything comes in at a sensible level, your faders have room to balance. If every fader sits at -30 because everything comes in too hot, every small move becomes fiddly.

Gain vs fader: what's the difference?

• Gain is the level a sound enters a stage with. Think of the gain on your audio interface while recording, the gain of a clip or region, or a gain plugin at the start of your chain.
• The fader sits after your plugins in most mixers. It sets how loud that track is in your mix, but it doesn't change how hard the sound hits your plugins.

That's the big takeaway: if you want your compressor to work less hard, don't touch the fader. Turn down the level before the compressor.

Gain staging in 6 steps

1. Start at the recording. Record with room above your loudest part. A recording that already clipped can't be saved by gain staging. Here's how to prevent that: distorted recording? How to prevent clipping.
2. Set your faders to 0 dB and bypass the effects on your master, especially a limiter. That way you see and hear what's really going on.
3. Bring every sound to a sensible level before the first plugin. Use clip gain, region gain, channel volume or a gain plugin. Turn hot samples down, bring quiet takes up a little. Not everything has to peak near 0 dB: according to Image-Line, a recording that peaks at -12 dB or less is perfectly fine.
4. Check the level after every plugin. Toggle the plugin on and off. Does the sound get a lot louder or quieter? Fix that with the plugin's output or gain knob. That way you hear whether the plugin makes it better, not just louder.
5. Only now build your balance with the faders. For example kick and 808 first, then the rest of the beat, then your vocal on top.
6. Keep your master below 0 dB. Play the loudest part, usually your hook. If your master peaks too high, pull all your tracks or group buses down by the same amount so your balance stays the same. Is your mix going to mastering? Read how much headroom to leave for mastering.

Gain staging in FL Studio

• Channel volume in the Channel Rack. Every channel has a volume knob. According to the manual, Sampler channels load at a default 55% (about -5.2 dB). If a sample is too quiet, turn that knob up. Too loud? Turn it down before the sound hits your mixer.
• A volume plugin first on your insert. Put Fruity Balance in the first effect slot, for example. Its Volume knob sets the level before it reaches your EQ and compressor.
• Insert meters are a guide. Image-Line describes them as a guide to the relative volumes of your tracks. They turn orange above 0 dB to get your attention. On an insert that's not automatically a problem. On your master track it is.
• Set your final level with the master fader. The manual says to adjust the final level with the master track fader or the main volume knob. The Monitor Volume knob only changes what you hear, not your export.

Gain staging in Logic Pro

• Region gain in the inspector. Select an audio region, open the inspector and double-click Gain. According to Apple you can enter a value between -30 and +30 dB. Perfect for bringing a hot sample or a quiet take into range without another plugin.
• The Gain tool. Choose the Gain tool from the Tool menu in the Tracks area and drag vertically over a region. If you select just part of a region with the Marquee tool, Logic creates a new region with the gain change applied. Handy for that one ad-lib that jumps out.
• The Gain plugin first on your channel strip. Apple describes the Gain plugin as a tool to adjust the level or phase of input signals. Put it in the first slot and you decide how hard the rest of your chain gets hit.
• Keep an eye on your Stereo Out. That's where your mix leaves Logic, and that's where you don't want to see clipping.

Gain staging and vocal presets

If you use a vocal preset, gain staging matters even more. A preset comes with fixed settings, including EQ and compression. If your vocal comes in much hotter than normal, the compressor squashes harder than intended. If it comes in very quiet, not much happens. So bring your vocal to a healthy level first with region gain or a gain plugin, then load the preset. It saves you a lot of tweaking. Looking for a starting point for your voice?

Common mistakes

• Pulling the fader down to calm a compressor. The fader sits after the compressor. Lower the level before it.
• Comparing plugins at different volumes. Louder almost always sounds "better". Match the level before you judge.
• Pushing everything as close to 0 dB as possible. A louder recording isn't a better recording. Leaving room is fine.
• A limiter on your master that hides your problems. Listening through it for a moment is fine, but switch it off while you set your levels.

FAQ

Do I need gain staging if my DAW runs in 32-bit float?

Yes. Inside the FL Studio mixer you have plenty of headroom in practice, but your plugins still react to the level going in. And your master and your export can still clip.

What level should a single track be at?

There's no fixed number. Make sure nothing clips, that your plugins get a sensible level and that your faders have room to move. Image-Line calls a recording peaking at -12 dB or less perfectly fine.

What's the difference between gain staging and headroom?

Headroom is the space between your highest peak and 0 dB. Gain staging is setting your levels at every step, so you have enough headroom everywhere and your plugins do what you expect.

Should I gain stage first or mix first?

Gain stage first. It takes a few minutes at the start of your mix and saves you a lot of tweaking later.
