Wolf Spectrum is a spectrogram plugin. It can be built as an LV2 or VST plugin and as a standalone Jack application.

• Supports both log and linear frequency scaling
• Resizable UI

You can find some precompiled plugin binaries in the Releases tab. Some packages are also available for Ubuntu and Arch Linux:

Download the plugin from the pdesaulniers/wolf PPA:

sudo apt-add-repository -y ppa:pdesaulniers/wolf
sudo apt-get update
sudo apt-get install wolf-spectrum

To install the latest release:

sudo pacman -S wolf-spectrum

A git package is also available in the AUR.

First, clone the repo (note the "--recursive" argument):

git clone --recursive https://github.com/wolf-plugins/wolf-spectrum.git
cd wolf-spectrum

Then:

BUILD_VST2=true BUILD_LV2=true BUILD_JACK=true make

Prepend WIN32=true or MACOS=true to the command if applicable.

All plugin builds will then be placed in the bin folder. Copy them to their appropriate place so that your plugin host can find them, and you're done :)

This project uses git submodules. Thus, to update your local copy of the repo, you need to run the following commands:

git pull
git submodule update --init --recursive

You should then be able to build the plugin with the most recent changes.
