What is gain staging?

By Dan Murtagh · Updated

Short answer: gain staging is setting the level at each point a sound passes through, from the input to the mix bus, so nothing clips and level-sensitive plugins get the level they expect. In a DAW that means recording with headroom, trimming tracks before their plugins, and leaving room on the mix bus. It isn’t the balance: that’s the faders, and you set it by ear.

The drums from an indie rock track. Clipping turns them up until the peaks would pass full scale by 12 dB, and cuts them off at full scale, as an overloaded input or output would. Hot into a compressor plays one compressor (4:1, 10 ms attack) set for 3 dB of gain reduction, then the same settings fed 12 dB hotter, where it reads about 11.5 dB: the body flattens and the hits stick out. Both sides play at the same loudness, so you hear what the level did, not the level. Start with the drums on their own, then hear them with the band.

Why gain staging matters

Every stage has a level where it works best and a point where it runs out. Go past that point and the top of the wave is cut off: clipping. Stay far under it and the signal sits closer to the noise floor, and level-sensitive plugins barely react.

Most DAWs mix in floating point, so a channel that reads over 0 dBFS usually isn’t clipping inside the mix yet. The trouble is at the edges: the converter when you record, the output and a fixed-point bounce, and any plugin that reacts to how hard it’s hit. Don’t lean on it: keep every channel under 0 dBFS anyway.

Where to watch the level

  • Recording: the converter clips at 0 dBFS, and that can’t be undone. Leave room for the loudest moment.
  • Into each plugin: compressors, gates, saturation and analogue-modelled plugins react differently to a different input level.
  • The mix bus: keep it clear of clipping, with headroom to spare.
  • The bounce: a 24-bit or 16-bit file can’t hold anything over full scale.

That second point is the demo’s other half. A compressor’s threshold sits at a fixed level, so feed it 12 dB more and the same settings squash far harder. Many analogue-modelled plugins expect an average level well under full scale; their manual says where.

How to gain stage a mix

  1. Record with headroom. Peaks well under 0 dBFS. At 24-bit, a few dB lower costs you nothing you’ll hear.
  2. Trim before the plugins. Use clip gain or a trim at the top of the chain, so each track reaches its first plugin at a sensible level.
  3. Match in and out. Set each plugin’s output so bypassing it doesn’t jump in level. Then you’re judging the sound, not the volume.
  4. Build the balance with the faders. As a starting point, the kick and snare often peak around −10 to −6 dBFS. Bring the rest up around them.
  5. Check the mix bus. Nothing clips, and there’s headroom to spare.

Gain staging isn’t balance

Gain staging is level for the equipment. Balance is level for the song: how loud each part sits against the others. You can gain stage perfectly and still have the vocal too loud and the drums too quiet. Once the levels are healthy, the faders are an ear skill.

Questions

Does gain staging matter in a DAW?

Yes, at the edges and in the plugins. A floating-point mix rarely clips inside a channel, but the input, the output, a fixed-point bounce and level-sensitive plugins all care how hot the signal is.

What level should I gain stage to?

Peaks well under 0 dBFS when recording, and the kick and snare peaking around −10 to −6 dBFS as a starting point in the mix. For an analogue-modelled plugin, check its manual for the input level it expects. With a good recording it becomes a feel more than a number.

Is gain staging the same as setting the faders?

No. Gain staging keeps every stage in a healthy range. The faders set the balance between parts, and that’s judged by ear against the song.

Should I use clip gain or the fader?

Clip gain or a trim to set the level going into the plugins, and the fader for the balance. In most DAWs the fader comes after the plugins, so it doesn’t change how hard that track’s own plugins are hit.
