Sound

The Squatch plug-ins.

Ten effects for your DAW, as Audio Unit, VST3 and CLAP.

Squatch Setup's Choose screen: the ten plug-ins ticked, and Audio Unit, VST3 and CLAP chosenCapture

What it does

A tuner, a gate, a compressor, three drives, an EQ, a cabinet, a hall and a limiter, from the same engine as the browser rig.

Who it’s for

Players and producers who want our pedals in their DAW.

Why we built it

So the sound you try in the browser is the sound you record.

What we’re proud of

Every bundle is signed by us and notarized by Apple. All 10 Audio Units pass auval, the CLAP builds pass 35 checks with 0 failed, and the VST3 builds pass 537 tests with 0 failed.

How it works

One engine, three formats, checked twice.

  1. Each pedal is one block of our open DSP engine, the same code the browser rig and the pedal hardware run.
  2. One adapter wraps every block as CLAP, and the same build makes the VST3 and Audio Unit versions.
  3. Our release workflow builds them from the tagged source, signs every bundle with our Developer ID, and Apple notarizes them.
  4. Before a release ships, each format goes through its own validator: auval, the CLAP validator and Steinberg's VST3 validator.

Check your download

Trust it because you checked.

Three lines in Terminal. Each one checks something different, and none of them needs to trust this page.

  1. Its fingerprint matches
    shasum -a 256 ~/Downloads/squatch-dsp-plugins-v0.2.2-macos.pkg
    It should print aef521fe5e91692c… (the whole value is above, and in SHA256SUMS on the release page).
  2. GitHub built it from our source
    gh attestation verify ~/Downloads/squatch-dsp-plugins-v0.2.2-macos.pkg -R Squatch-Stack/squatch-dsp
    Needs GitHub’s gh tool. It checks the build record our release workflow signed.
  3. Apple notarized it
    spctl -a -vv -t install ~/Downloads/squatch-dsp-plugins-v0.2.2-macos.pkg
    It should say accepted, Notarized Developer ID.

Install guides

If something is off

Fixes for the usual snags.

A plug-in doesn't show up

Restart the host, then use its rescan step above. For Logic and GarageBand, run this in Terminal; it should end with AU VALIDATION SUCCEEDED: auval -v aufx SqTn SqSt (that one is the Tuner).

Logic says a plug-in failed validation

Open Plug-in Manager, select it and click Reset & Rescan Selection. If it still fails, restart your Mac and try again, then write to us with what auval prints.

Uninstall: every file, exactly

Each plug-in is one bundle in your plug-in folders (or the same paths under /Library, if you used the installer). Move these to the Trash, then restart your host:
