Synthwave Mix Checker — Does Your Track Drive, or Just Drift?
Synthwave lives and dies by excess: sawtooth bass the size of a freight train, gated snares that crack in a parking garage, pad layers stacked four deep. The aesthetic is maximal — but the mix has to be surgical, or all that neon collapses into midrange hash. A track that looks right in the DAW can still turn into a wall of buzz on a car stereo. MixDiagnose reads your file the way a retrowave mastering engineer would: not "is it loud?" but "can I still hear the bass line under the pads, and does the snare still hit when the chorus drops?"
The frequencies where synthwave fights itself
Synthwave isn't a vocal-forward genre. Its three problem zones are all instrumental, and all about mass:
- 40–100 Hz. The analog-style sub bass — the heartbeat of every outrun track. Too much and it detonates your limiter on every note; too little and the track loses its pulse.
- 300–800 Hz. The sawtooth horn zone. Every supersaw, every pulse-lead, every FM pluck dumps energy here. Three layers that sound fine solo become a 6 dB brick that hides your arpeggio.
- 6–12 kHz. The shimmer — bell pads, hi-hat sparkle, the "neon" top end. Push it and you fatigue the ear in two minutes; pull it and the track sounds blanketed.
Mistakes synthwave producers make
Stacking supersaws without slotting. Three detuned saw leads at 300–800 Hz don't make a "bigger" lead — they make mud with a vowel. Each layer needs its own EQ pocket or the arpeggio disappears. We flag midrange stacking band by band.
Gated reverb snares that eat the whole mix. The signature 80s snare — big body, long verb tail, gate clamped shut — is gorgeous alone and brutal in context. A 400 ms reverb bloom at 2–4 kHz masks your lead every time the snare fires. We measure reverb decay against dry signal so your snare is a hit, not an ambush.
"Loud = retro." No. Streaming normalizes to -14 LUFS. A track mastered to -7 LUFS gets turned down and loses the punch the loudness was meant to deliver. We check loudness, true peak, and crest factor against every major target so your loud is real, not theatrical.
Sub bass without headroom management. A -8 dBFS sawtooth at 60 Hz eats 3 dB of master headroom before anything else plays. We show where your low end sits and whether the limiter is working at rest.
What MixDiagnose checks for synthwave
- Saw-stack overlap detection at 300–800 Hz — exact dB buildup per band so you can slot each layer.
- Sub bass energy and headroom from 40–100 Hz — is the bass driving or detonating your limiter? We show the low-end crest factor alone.
- Gated reverb vs. dry signal — decay time and energy ratio on the snare band (2–4 kHz), so your verb is an accent, not a smother.
- Shimmer and harshness at 6–12 kHz — quantified against retrowave references, not pop standards.
- Stereo width per band — synthwave needs wide pads over a mono-center bass. We check you have that, not a wide-everything wash.
- Streaming loudness via LUFS checker — integrated loudness and true peak vs. Spotify (-14), Apple (-16), YouTube (-14). For synthwave we flag anything above -9 LUFS as loudness you're paying for in punch.
Every finding names the frequency, the dB value, and a DAW move. The spectral analyzer lays your full frequency map beside a synthwave reference curve — screenshot it and find where your neon is actually fog.
