sndwch install guide

Verify the installer before you run it, then put the pair around one plugin.

Before you install: Windows x64 only, and the build is unsigned. Check the SHA-256 value before you run it.

Install

Download the current build from your account.
Run the hash command and compare the result with the published SHA-256 value.
Install the build, then load sndwch in your VST host.
Place it around the FX chain you want to compare, and level-match with input and output trim.

Getting an honest comparison

Match first: Bring the output level back before you compare the two states.
Listen for: Tone, movement, punch and balance — not loudness.
