Drill mix analysis — scored against real Drill references

Upload a Drill mix and Unveil grades it against a hand-curated reference set of commercially released Drill records — not a generic loudness number. It checks the things that actually matter for Drill: sliding 808 control and mono-safe sub. Then it hands you the specific fixes for your DAW.

What defines a drill mix

Drill is built around a few elements doing very specific jobs: a sliding 808 that carries both the bass and the melody, sparse and tense drums with rapid triplet hi-hat patterns, dark pads or strings, and a dry, forward, often double-tracked vocal. The mood is cold and aggressive, and the mix has to be loud and tight to deliver that.

Reference targets are about -8.5 LUFS integrated with a dynamic range near 5 dB, which makes drill one of the loudest and most compressed genres. That is a stylistic and competitive choice, and also a trade-off: it leaves little room for dynamics, so every decision about the 808, kick and vocal matters.

Tonal balance and where it breaks

Common faults: a sub that is huge on studio monitors but vanishes on a phone, an 808 that drowns the kick, and a harsh hi-mid band from stacked hats, clap and vocal distortion.

Sub (20-80 Hz): dominant. The 808 fundamental usually sits between 35 and 60 Hz. This band needs to be strong but controlled, and mono.
Bass (80-250 Hz): where the 808's body and the kick's punch live. Without definition here, the bass is invisible on small speakers.
Low-mid (250-800 Hz): kept lean. Cut 2-4 dB around 250-400 Hz on the 808, pads and vocal to avoid a boxy sound.
Mid (800-2500 Hz): the vocal's body and the snare or clap. Should be clean and forward.
Hi-mid (2500-6000 Hz): vocal presence, snare snap and hi-hat attack. Often the harshest region in a loud drill mix, so watch it.
Air (6000-16000 Hz): hi-hats and vocal sheen. Present but not piercing.

Sliding 808s and the kick

The 808 is a pitched, sustained bass, and the slides between notes are part of the melody. Because its fundamental is so low, small speakers reproduce little of it. Add harmonics with saturation or a soft clipper so the note shows up at 100-400 Hz. A common technique is to split the bass into a clean sub below about 100-120 Hz and a saturated upper layer above it, so you can control each separately.

Make sure each 808 note is tuned to the key of the track. An 808 that is a quarter-tone off the melody sounds wrong even if the listener cannot say why. Check slides for pitch overshoot, and shorten release so notes do not overlap in a way that creates muddy low-end buildup. Overlapping 808 tails also add up in level: two sustained notes at once can make the bus peak several dB higher than expected.

For the kick, choose a short, clicky sample (attack around 2-5 kHz) so it reads through the 808. Use sidechain compression on the 808 triggered by the kick, with 3-6 dB of reduction and a release of 50-120 ms, or carve complementary EQ, for example kick emphasis at 60-80 Hz and 808 at 40-55 Hz. Both approaches are valid; sidechain gives a pumping effect that some producers want and others avoid.

Mono sub, hats and stereo

Keep everything below roughly 100-120 Hz in mono. A wide sub causes phase cancellation on club systems and mono phone speakers, losing the weight the genre depends on. A simple way is to use a mid/side EQ or a stereo-width tool to collapse the band below 120 Hz, then check the mix with a mono-sum switch.

Hi-hat patterns in drill use fast triplets, rolls and sudden dropouts. These are programmed, not played, so velocity variation matters: vary hat velocity by 10-30% to avoid a machine-gun feel, and consider small pan differences between hat layers. Because hi-hats sit in the sensitive hi-mid and air bands, cut harshness with a gentle dip around 4-6 kHz and low-pass at 14-16 kHz if they are brittle. Pads and strings can be wide, but the vocal, kick, snare and 808 stay centered.

Drill vocals are typically dry and upfront. Use a short reverb or slap delay (80-120 ms) for presence, with delay returns filtered to avoid cluttering the center. Double-tracked adlibs panned left and right create width without weakening the lead.

Dynamics and loudness: what -8.5 LUFS and 5 dB really mean

At about -8.5 LUFS, a drill reference is roughly 5.5 dB above the -14 LUFS that Spotify and YouTube aim for, and 7.5 dB above Apple Music's -16 LUFS. With normalization on, the platform turns the track down by that amount, so heavy limiting does not make it play louder than a quieter master; it only changes its character. A dynamic range of about 5 dB means that peaks are only about 5 dB above the average, so transients are already compressed.

The risk is distortion. With a loud 808, the limiter reacts to every low note, which pumps the rest of the mix. Fix this before the limiter: clip or saturate the 808 to bring its peaks down, which reduces the work the limiter has to do. Aim for no more than 3-6 dB of limiter reduction. If the vocal sounds pushed back every time the 808 hits, lower the 808 or compress it more rather than pushing the limiter harder. The true-peak ceiling should be about -1 dBTP, and drill's clipped transients make inter-sample overs likely, so confirm it with a true-peak meter.

Step-by-step workflow

Tune the 808 to the key and set its slides and release so notes end cleanly.
Balance 808 against kick: pick the sidechain or EQ split and set it by ear on small speakers.
Add saturation to the 808 so it translates at 100-400 Hz, and make the sub region mono.
Carve 2-4 dB around 250-400 Hz on the 808, pads and vocal.
Process the vocal: high-pass at 80-100 Hz, compression at 3:1 to 4:1, de-ess around 6-8 kHz, and a short delay.
Set hi-hat velocities and tame 4-6 kHz harshness.
Use a soft clipper before the limiter to catch the loudest peaks, then limit to about -8.5 LUFS with a ceiling near -1 dBTP.
Check on a phone speaker, headphones and a subwoofer or club-style system if available.

Worked example, mistakes and checklist

Your mix measures -6.5 LUFS and sounds fuzzy. The limiter is taking 9 dB off the loudest 808 notes. Pull the 808 down by 2 dB, add a soft clipper that removes 1-2 dB of its peaks, and reduce limiter gain by about 2 dB. You land near -8.5 LUFS with cleaner highs and a punchier kick, and the vocal no longer ducks.

An 808 off-key or with overlapping tails that build up.
Wide sub that collapses in mono.
Letting the limiter handle the 808 instead of controlling it earlier.
Harsh hi-hats and distorted vocals stacking in the 2.5-6 kHz band.
Checklist: 808 in key and mono below about 120 Hz, kick audible over the 808, low-mids lean, hi-mid harshness controlled, vocal upfront, loudness near -8.5 LUFS, true peak at about -1 dBTP or lower. Re-measure after changes.

Questions

What loudness should a Drill mix hit?

Unveil targets roughly -8.5 LUFS integrated for Drill, but loudness alone doesn't make a mix — it's weighed alongside dynamics (DR ~5), tonal balance, phase, and frequency conflicts.

Is the Drill scoring just a generic algorithm?

No. Drill is scored against measured statistics from a curated set of released Drill tracks, so the targets reflect how the genre is actually mixed and mastered.

Is it free?

Yes — analysis is free with a quick sign-up. The optional Fix My Mix mastering pass is paid.
