Mixing Vocals Like Sam Smith: Auto-Tune, Scheps 73, SSL Channel, Pro-MB, Pro-DS, RVox, Reverbs, Delays, and Stereo Widening

Sam Smith-style vocals need precision without losing emotion. The vocal has to stay intimate, smooth, and polished, but it also needs enough control to sit confidently inside a modern pop production. The transcript for this chain shows a very structured approach: clean pitch correction, tone shaping through analog-style EQ, controlled multiband management, careful de-essing, then a heavily organized send setup for reverbs, delays, and stereo spread.

What makes this workflow useful is that it is not just one insert chain. It is a full vocal environment. The inserts stabilize the lead, while the buses create space, width, and emotional lift without making the vocal feel disconnected from the center.

1. Start with Natural Pitch Correction

The chain opens with Auto-Tune set with a retune speed between 20 and 35 depending on the vocalist, plus humanize at 20. According to the transcript, this range is the sweet spot for keeping the correction natural.

That makes sense for a Sam Smith-style vocal. The performance has to feel emotionally believable, so pitch correction should tighten notes without flattening the phrasing or removing expressive bends.

2. Add Harmonic Weight with Scheps 73

Next comes Waves Scheps 73 for vintage-style tone shaping. The transcript specifies a 3 dB boost at 3 kHz and another 3 dB boost at 220 Hz, with the note that these settings may need adjustment depending on the vocal.

This processor does more than simple EQ. It adds the type of warm, slightly driven tone associated with a Neve-style front end, helping the vocal feel denser and more finished before the more surgical control stages start.

3. Use the SSL Channel for Controlled Brightness and Midrange Shape

The SSL Channel stage is where the chain gets especially interesting. The transcript sets a low cut at 100 Hz and a high cut at 10 kHz, then still boosts 3 dB at 14 kHz, 3 dB at 7 kHz, and another 3 dB at 800 Hz.

That high-cut-plus-air-boost move is presented as an unusual trick. Conceptually, it helps shape the top end so the vocal feels enhanced but not overly brittle. Combined with the upper-mid and low-mid boosts, it builds a vocal that is present, smooth, and supportive in the center.

4. Control the Upper Range with Pro-MB or Waves C6

After the broad EQ stages, FabFilter Pro-MB is used to control higher frequencies dynamically. The source sets one band from 1 kHz to 5 kHz and another from 5 kHz to 20 kHz, with nearly fast attack, medium release, ratio of 2, and only about 2 to 3 dB of maximum gain reduction on each band.

This is an elegant way to keep the vocal present without letting the upper mids and top end become aggressive. The transcript also notes that Waves C6 was used as a replicated alternative, so the real principle is dynamic tonal control rather than dependence on one specific plugin.

5. De-Ess with Restraint

FabFilter Pro-DS follows, with the target being a maximum of 6 dB of reduction. The source explicitly warns that de-essing must be handled carefully: take too much and the vocal sinks into the mix, take too little and the top end becomes distracting.

That balance is especially important here because the chain uses several presence and air-enhancing moves. The de-esser has to preserve clarity while stopping the sharpest consonants from dominating the effects sends.

6. Finish the Insert Chain with RVox

Waves RVox is used after the tone and control stages, aiming again for up to about 6 dB of gain reduction. This acts like a final leveling layer that helps the vocal stay confidently in front.

At this point, the inserts are done. The lead should already sound stable, polished, and emotionally readable before the ambience and width network is introduced.

7. Build the Reverb Network with Filtered Inputs

The first reverb bus uses an EQ before the reverb, rolling off highs at 8 kHz with a steep slope, followed by Soundtoys Little Plate with around 3 seconds of decay and a low cut at 400 Hz. The transcript explains that filtering before the reverb prevents sibilance and muddiness from building up inside the effect.

A second bus repeats the filtered-input idea, but uses Valhalla VintageVerb in the Dirty Plate mode. A third bus adds a short Valhalla Plate with Radium mode and a decay around 0.8. Together, these buses create multiple layers of space rather than relying on one generic reverb.

8. Use Multiple Delays for Different Jobs

Bus 4 uses D16 Repeater, or a replicated Waves H-Delay version, as a super short tape-style delay that adds dimension. Bus 5 becomes the throw delay with a half-note time, a little feedback, 100 percent wet mix, and a Space Echo style, followed by a hall-style reverb to push the delay back.

Bus 6 uses EchoBoy Jr. as a quarter-note studio tape delay, while Bus 7 uses another EchoBoy Jr. set to eighth note even though the transcript notes Kevin Davis did not use it in the reference song. This routing gives the mix different delay personalities for different moments instead of forcing one echo to do every job.

9. Add Width Without Destroying the Center

The final buses handle stereo spread. Bus 8 uses Valhalla Space Modulator as a chorus-like widener, again with a high cut around 8 kHz before the effect to reduce high-frequency artifacts, followed by an S1 Imager to widen further.

Bus 9 uses EchoBoy set manually to 17 milliseconds with no feedback, sync disabled, and a Digital Chorus style. This is another classic widening move, adding spread while the main vocal remains stable and centered.

Practical Workflow Summary

1. Tune naturally first with moderate retune speed and controlled humanize.
2. Use Scheps 73 to add analog-style tone and thickness.
3. Shape the vocal with SSL filtering and controlled brightness boosts.
4. Use Pro-MB or C6 for light dynamic control in the upper spectrum.
5. De-ess carefully and finish leveling with RVox.
6. Build multiple filtered reverbs rather than one overly broad ambience.
7. Use distinct delay buses for dimension, throws, and rhythmic support.
8. Create width on dedicated buses so the center lead stays intact.

Frequently Asked Questions

Why not use a faster Auto-Tune setting for this type of vocal?

Because a Sam Smith-style performance depends on emotional phrasing and natural pitch movement. Faster retune can over-flatten the vocal and make it feel less human unless that effect is intentionally part of the production.

What is the advantage of using both Scheps 73 and SSL Channel in one chain?

Scheps 73 provides harmonic color and musical broad-stroke tone, while the SSL Channel refines the vocal with a different style of EQ shaping and filtering. Using both gives the chain more character and control than relying on only one EQ stage.

Why keep Pro-MB or C6 gain reduction so low?

Heavy multiband compression can make the top end small, flat, or lifeless. Keeping it around 2 to 3 dB lets the vocal stay open while still catching harsh or unstable upper-range energy.

Why filter the reverbs before they receive the vocal?

Because unfiltered sibilance and low-mid buildup can make reverbs sound messy very quickly. Pre-filtering the send helps the effects sit around the vocal instead of competing with its clarity.

Why use widening buses instead of widening the main lead insert directly?

Keeping widening on separate buses preserves a strong center vocal while giving you independent control over spread, tone, and blend. That usually translates better in dense arrangements and more reliably in mono-compatible mixes.
