Sideria Audio Lib

What is this?

This is a hand-made audio library which is the basis for all of my plugins and pedals. It is written in pure C-like C++ (no new, no v-tables, only c-arrays, etc.) for maximum portability to both PCs and also Arm/microcontrollers. The siderialib/ folder contains the backend audio code - e.g., filters, delays, etc.. This code can then be linked to different "frontends" in the projects/ folder, like a JUCE VST3 plugin or an Arm chip like the Electro-Smith Daisy.

Everything that can easily be made into a CMake project has been made into one. If you build this project at the top level, the library and all of the JUCE plugins will be built. However, any projects which use the Electro-Smith Daisy will need to be compiled separately as they do not support CMake. See the next section for details.

Getting Started

Pre-requisites

Install gnuplot however is appropriate for your machine. gnuplot is used in testing to generate frequency analysis plots.

brew install gnuplot

Install the Daisy arm toolchain

Build

First, compile JUCE.

cmake . -B cmake-build -DJUCE_BUILD_EXAMPLES=ON -DJUCE_BUILD_EXTRAS=ON

Then, set up build profiles

• Set Debug profile with default toolchain output to cmake-build-debug, with "Build Type" set to "Debug"
• Create new CMake profile with the CMake flag -DCMAKE_TOOLCHAIN_FILE=<PATH_TO_PROJECT>/external/libDaisy/cmake/toolchains/stm32h750xx.cmake. This will make sure CMake knows how to use the arm compiler properly
• Make sure "Build Type" is "Debug" and set CMake profile's output to cmake-build-daisy-debug
• Now, clone these two profiles, and make sure their "Build Type" type is "Release", otherwise the same.

Now, running the cmake build profiles should work fine, and you should get four build folders: cmake-build-daisy-debug, cmake-build-debug, cmake-build-daisy-release, cmake-build-release

Once those are built, you can start working on the building the projects based on the daisy.

• Make sure all git submodules are fetched
• Compile libDaisy - cd external/libDaisy; make all
• Compile DaisySP - cd external/DaisySP; make all
• Compile the desired project cd projects/X-daisy; make all

By default, this will compile a release version. If you want to make a debug version, instead of make all, do DEBUG=1 make all.
