Spicerack on Vocals: 4 Starting Points for Warmth and Grit

A clean vocal can be perfectly recorded and still feel flat. Distortion is how you add weight, presence or edge, but it is also the quickest way to make a vocal harsh, noisy or small. This guide gives you four ways to start with Spicerack, our creative distortion plugin, so you can add the harmonics you want without paying for them somewhere else.

Quick answer: For warmth, use the Tube algorithm with a low Drive. For presence, use Amp with the EQ placed before the distortion. For edge, push the Drive on the wet signal and blend it under the dry vocal. For an effect, use Lo-Fi with a narrow EQ at 100% Mix. In every case, calibrate the Auto Gain Compensation, turn on linear phase when you blend, and use the gate when the distortion is heavy so breaths and noise stay clean.

Why distortion on vocals is different

A vocal is the most exposed element in a mix, and three things make distortion on vocals harder than on a guitar or a synth:

• It reacts to level. Loud syllables distort more than quiet ones. Fab Dupont points out the same thing when putting a tube preamp on a master bus: the louder choruses hit the tubes harder than the verses. Read more in Mixing with tube preamp | Fab Dupont.
• It raises the noise floor. As our manual puts it, distorting a signal often lowers the signal-to-noise ratio, so quiet parts such as mic bleed can end up as loud as the loud parts. On a vocal, that means breaths, room tone and headphone bleed.
• It can hollow out a blend. Most distortion plugins shift phase unevenly, so a distorted copy mixed under the dry vocal can thin the midrange. We explain why in Parallel Distortion: The Trick Behind Aggressive, Clean Mixes.

Saturation can also push sibilance forward, so check your s and t sounds with the plugin on before you commit.

Before you start: three settings that apply to every vocal

1. Calibrate the Auto Gain Compensation. Press Calibrate while the vocal plays and Spicerack analyzes the sound and applies a volume compensation profile after the Drive knob. You can then turn the Drive up without big jumps in level and judge the tone, not the volume. The compensation does not include the EQ module.
2. Watch the distortion meter. It shows the amount of distortion applied, not the audio level. At 0% Drive the signal stays untouched, and if the needle does not move, your vocal is not being distorted. If the input is too quiet to distort, use the +18 dB boost switch rather than the Input knob; the manual advises against using the Input knob too much so the internal gain staging stays intact.
3. Match wet and dry. When you blend with the Mix knob, turn on the linear phase switch for a clean blend. It costs more CPU and adds latency, so use it when mixing rather than while tracking. Then set the Wet Gain so the orange (wet) and white (dry) gauges hover in the same area.

The settings below are starting points. Every voice, microphone and song is different, so adjust by ear and compare with the bypass button at the same loudness.

At a glance: four starting points

Starting point 1: warmth with Tube

Use it when: a clean vocal sounds thin, digital or too close to the front of the speakers.

The Tube algorithm is modeled after AU7 tubes and recreates their harmonic content. The manual describes it as a rather dark tone that is perfect for an analog, vintage sound, which makes it a natural first choice for lead vocals.

• Drive: start low. Raise it until the distortion meter just starts to move, then stop.
• EQ: leave it after the distortion (the default). A high-pass filter removes low-end build-up, and the Tone control, which works as a tilt, lets you brighten the result if the tube sound is too dark.
• Mix: blend it in with linear phase on. If you want a way in, try the Vocal - Warmth preset from the preset list and see what it changes.

Keep it subtle. On the lead vocal of the Lifeboats mix with Tony Maserati, covered in Tony Maserati: Adding Saturation to the Lead Vocal, the saturation stays light most of the time and is automated up only on the last word of the chorus, with the vocal level pulled down slightly to compensate. To compare tube warmth with tape, read Tape Saturation vs Tube Saturation: When to Use Each.

Starting point 2: presence with Amp

Use it when: the vocal gets buried behind guitars, synths or a dense chorus.

Amp is modeled after high-gain guitar amps with several gain stages. It tends to saturate the medium to high frequencies, which is useful for cutting through a mix.

• EQ before the distortion: use EQ Swap so the EQ comes first. Place a high-pass filter above the low end of the voice, somewhere around 150 to 250 Hz as a typical start, so the lows do not feed the distortion (the dry vocal in your blend still carries them). The distortion will still create harmonics above and below the filters you set.
• Gate on: set the threshold so only the louder phrases get distorted and the breaths and room tone stay clean.
• Mix: keep it low, with linear phase on, and check the sibilants.

Starting point 3: grit in parallel with Drive

Use it when: the vocal needs edge, attitude or aggression without losing clarity, as in rock, rap or a dense electronic mix.

The Drive algorithm is inspired by our Sugar plugin and is described in the manual as a modern, effective distortion. Fuzz tends to saturate the low frequencies, which can be too heavy on a voice, so save it for effects.

• Push the Drive on the wet signal until it sounds more aggressive than you would ever use alone.
• EQ before the distortion with a high-pass filter, and use the bell to choose the region you want to excite.
• Gate on so quiet breaths do not get lifted along with the grit.
• Mix: turn on linear phase and then bring the Mix knob up from zero until the grit appears under the clean vocal.

A useful trick when you are unsure how much to blend: dial in fairly heavy saturation, then back the mix off until you are almost at zero, switching bypass on and off as you listen. Puremix describes it in its lesson on Fab Dupont's tube preamp. For the phase reasons behind parallel blending, see Parallel Distortion Explained, and for how the gate works on drums, Why Your Distortion Ruins Your Drums.

Starting point 4: a radio effect with Lo-Fi

Use it when: you want a phrase, an intro or a bridge to sound like a telephone, a radio or an old sample.

Lo-Fi down-samples and bit-crushes the sound. Pair it with the EQ in front of the distortion to define the band.

• EQ before the distortion: raise the high-pass and lower the low-pass to leave a narrow band. The filters have slopes from 12 to 48 dB per octave, so you can make the edges as steep as you need.
• Mix at 100% (the default) for a full effect, or blend a little dry vocal back for a more natural result.
• Automate it: use the bypass button or the Mix knob to bring the effect in on one phrase or section only. There is also a Vocal - Radio effect preset to start from.

Bonus: background vocals with Console Remote

Distorting every track a little is often more natural than distorting a bus, and Console Remote makes that practical. Put a Spicerack on each background vocal, assign them all to the same channel, and open the remote from any instance. The Drive, Wet/Dry and Mix jog wheels move every instance in the channel by the same amount, so you can still fine-tune each track on its own. The D, T, A, L and F buttons switch all of them to Drive, Tube, Amp, Lo-Fi or Fuzz at once. We cover the idea in The Console Workflow and in Why Your Tracks Sound Sterile: The Missing 0.5% on Every Channel.

Spicerack or Sugar for vocals?

They solve different problems. Sugar is a four-band enhancer, with separate controls for the low, medium, high and air regions, plus its own saturation section; read Use Sugar as a Vocal Enhancer. Spicerack is distortion first: five algorithms, a gate and an EQ you can place before or after the distortion. Use Sugar to lift a band of the voice, and Spicerack when you want the harmonics themselves to be the sound. If you are not sure which tool you need, our guide to exciters, saturators and enhancers explains the difference.

Common mistakes

• Judging at different volumes. Louder sounds better at first. Calibrate the AGC and match the wet and dry gauges before you decide.
• Distorting the noise. Without a gate, heavy distortion lifts breaths and bleed.
• Blending without linear phase. A hollow midrange in a parallel blend is usually phase.
• Sending the lows into the distortion. A high-pass before the distortion keeps the vocal clear.

FAQ

What is the best distortion setting for vocals?

There is no single setting. Start with Tube at low Drive for warmth, Amp with the EQ before the distortion for presence, Drive blended in parallel for edge, or Lo-Fi with a narrow EQ for an effect, then adjust by ear at matched levels.

Should I use distortion in parallel on vocals?

Often, yes. A blended copy adds harmonics while the dry vocal keeps its clarity and transients. Turn on Spicerack's linear phase switch so the blend does not thin the midrange.

Which Spicerack algorithm is best for vocals?

Tube suits warmth, Amp suits presence, Drive suits modern grit and Lo-Fi suits effects. Fuzz tends to saturate the low frequencies, so it is better kept for special effects.

Does distortion make a vocal louder?

It can. Spicerack's Auto Gain Compensation calibrates a volume profile to your signal, and the orange and white wet/dry gauges help you check the blend. Compare with bypass at the same loudness.

Can I use the same settings on lead and background vocals?

You can start from the same algorithm, but background vocals usually need less. Console Remote lets you move all your background vocal instances together while keeping each one adjustable.

Is Spicerack included in Puremix?

Yes. Spicerack is included in the Core plan of Puremix, Process.Audio's sister company. See the Puremix plans.
