The Overhead(s)™

An overhead bleed collector, if you want to call it that — it reduces kick, snare, and tom bleed in your overheads, giving you more control over the shells in your mix. The mirror image of a de-bleed tool, working on the drum hits themselves rather than a static EQ cut. Free for Windows and macOS.

The Overhead(s) plugin in use: Six Walls header, lit stereo overhead-level meters with a Delta control, Blind Engine and Reference Engine panels each switched ON, kick and snare sidechain strips armed and metering, a Cymbal Protect knob, Strength, Mix, and Output Trim, and a live output-and-reduction spectrum with the reduction curve stepping up through the kick and snare range
Before you download Six Walls is one person building these in his spare time and giving them away.

Windows: the installers are code-signed — verified publisher Edwin Jones. A fresh signing certificate takes a little while to build reputation with SmartScreen, so for the first few weeks you may still see a “not commonly downloaded” note — click More info → Run anyway.

macOS: the .pkg and the bundle .zip are signed with a Developer ID and notarized by Apple, so they open with no Gatekeeper prompt. Universal — Apple silicon and Intel.

Reduces kick, snare, and tom bleed in your overheads, giving you more control over the shells in your mix — the mirror image of a de-bleed tool that strips overhead spill from the close mics. The cymbals share that broadband, transient territory, so it works on the drum hits themselves rather than a static EQ cut, and Cymbal Protect keeps their brightness untouched.

  • Blind engine — reference-free; a linear-phase STFT ducks shell-hit energy and tapers back above a tunable Cymbal Protect crossover.
  • Reference engine — feed in the kick/snare/tom close mics and a per-source adaptive filter learns each spill path and subtracts it.
  • Engines run alone or in series; delta monitoring.
  • Fixed ~85 ms latency, reported for delay compensation. Passes pluginval at strictness 10.

Hear it — the same overheads, untouched vs. Blind vs. both engines

Listen to the effect in each mode, then play its Delta to hear exactly what was removed.
