NOTE: This applies to both open source and commercial editions of Chocolatey.

1. Ensure you are set for organizational deployment

Please see the organizational deployment guide

  • Open Source or Commercial:
    • Proxy Repository - Create a proxy nuget repository on Nexus, Artifactory Pro, or a proxy Chocolatey repository on ProGet. Point your upstream to https://chocolatey.org/api/v2. Packages cache on first access automatically. Make sure your choco clients are using your proxy repository as a source and NOT the default community repository. See source command for more information.
    • You can also just download the package and push it to a repository Download

3. Enter your internal repository url

(this should look similar to https://chocolatey.org/api/v2)

4. Choose your deployment method:

choco upgrade voxengo-correlometer -y --source="'STEP 3 URL'" [other options]

See options you can pass to upgrade.

See best practices for scripting.

Add this to a PowerShell script or use a Batch script with tools and in places where you are calling directly to Chocolatey. If you are integrating, keep in mind enhanced exit codes.

If you do use a PowerShell script, use the following to ensure bad exit codes are shown as failures:

choco upgrade voxengo-correlometer -y --source="'STEP 3 URL'"

Write-Verbose "Exit code was $exitCode"
$validExitCodes = @(0, 1605, 1614, 1641, 3010)
if ($validExitCodes -contains $exitCode) {
  Exit 0

Exit $exitCode

Correlometer is a free analog-style stereo multi-band correlation meter AudioUnit, AAX and VST plugin for professional music production applications. It is based on correlation meter found in PHA-979 phase-alignment plugin.

Multi-band correlation meter is an advanced way to check for presence of out-of-phase elements in the mix. Broadband correlation metering reports overall phase issues and may misrepresent problems present in select spectral bands, while multi-band correlation meter easily highlights problems present in mid to high frequencies that are not easily heard by ear, but may still reduce clarity of the mix. Another application of multi-band correlation metering is phase- and time-aligning of channels and tracks, especially bass and bass-drum pairs, guitar mic and D.I. source pairs, two-microphone stereo recordings, etc.

Correlometer can display 4 to 64 individual spectral bands, with adjustable band quality factor that controls the degree of band’s selectivity. Averaging time of correlation estimator can be adjusted. Correlometer supports side-chain inputs for easy correlation estimation between separate audio tracks.

Package Specific

Package Parameters

The following package parameters can be set:

  • /NoVst2x86 - Do not install the x86 VST2 version
  • /NoVst2x64 - Do not install the x64 VST2 version
  • /NoVst3x86 - Do not install the x86 VST3 version
  • /NoVst3x64 - Do not install the x64 VST3 version
  • /NoAaxx86 - Do not install the x86 AAX version
  • /NoAaxx64 - Do not install the x64 AAX version
  • /NoShortcuts - Do not install shortcuts to manuals and uninstaller into start menu or onto desktop
  • /Vst2Path: - Installation path of the VST2 version
  • /Vst2x86Path: - Installation path of the x86 VST2 version on x64 CPU architecture
  • /InstallerPath: - Do not download the installer from the official Voxengo website and use the one passed with this argument instead. Use it, if you don't have an internet connection at your studio computer.
  • /CompanyPath: - Path of the company to put all program files in. Override if you want to have the program files at a custom location.

You must pass the package parameters like this:

choco install correlometer --package-parameters "'/NoVst2x64 /Vst2x86Path:${env:CommonProgramFiles(x86)}\VST2\Voxengo '"

Reduces the nupkg package file by deleting big binaries from the file.

  Reduces the nupkg package file by deleting all files from the .nupkg file that are not necessary anymore like installer files or 7z binaries.
  It keeps the following files and folders:

  The rest will be removed from the nupkg file.
