Back in the late 1990s, I worked with a very talented programmer, Pepijn Sitter, from The Netherlands, to create an audio effects processing software product called WaveWarp. We distributed it under the trading name Sounds Logical. It was critically acclaimed, winning an Editor’s Choice Award from Electronic Musician Magazine in 2001.
WaveWarp enabled you to build your own audio effects from a library of modular building blocks. In that sense, it’s architecture resembled Simulink, but was fundamentally much faster (even compared with the compiled version of Simulink deployed via the RealTimeWorkshop) on account of the fact that the WaveWarp audio engine (and each individual module) was written in highly-optimised C code (making extensive use of pointer arithmetic) such that it could process multi-channel audio in real-time, sample-by-sample, on a typical desktop PC of the age. Moreover, it had full multi-rate functionality (via a library of decimators, interpolators, polyphase filterbanks, etc) allowing for elaborate mixed sample-rate designs. It used the FFTW (Fastest Fourier Transform in the West) library for spectral analysis, just as MATLAB does now. The WaveWarp software worked in standalone mode or as a DirectX plugin, and even had a real-time interface to MATLAB (akin to the audioTestBench available in the MATLAB Audio Toolbox today).
Alas, WaveWarp is now long gone. Moreover, I lost track of the source-code years ago, and I don’t have a running version. Also, it has almost completely faded from the internet. I could find only this review on PCRecording.com.
Anyway, given that I find myself delving into the world of audio processing again, I thought it fitting to revive the logo.
