Hi all, I’ve just made one of my side projects public because I thought some of you might find it handy.
DSP Testbench is designed to help JUCE developers to analyse their DSP by providing a test harness for code inheriting from
juce::dsp::ProcessorBase. The harness provides signal sources, routing, analysis and monitoring functions.
You can read about all the handy features in the README.md - but the basic idea is that you can route various signal sources through A/B versions of your DSP code to assess the impacts of tweaks and optimisations. One of the niftiest features is a snapshot function which lets you reliably analyse the same segment of audio each time. This is really handy for checking an impulse response for example - and yes, impulse and step signal sources are provided
If you want to have a play, you can grab the repo from GitHub.
How to use
To make use of DSP Testbench, you need to include your own code, wrap it appropriately and build the project.
- Navigate to the
Source\Processingfolder and take a look at
ProcessorExamples.h/.cpp. This shows how to inherit from ProcessorHarness and shows examples of how to override the necessary pure virtual functions.
- Create a local branch of the repository before proceeding
- Copy (or create) your own code into the project folder
- Make sure you add these files to the Projucer project also
- Either extend
ProcessorExamples.h/cppor create your own wrapper class and include it in
- Instantiate your processor harness in the
- If optimising code, then use two separate wrappers and instantiate them separately
- Build, run and test!
