Software-defined declarative synthesizer live-coding in a jupyter notebook
summary
Live Rust code runs in Jupyter via evcxr and a custom library CAW (Combinatorial Audio Workstation) builds synthesizer modules as Functional Reactive Programming (FRP) signals sampled per frame (not per audio sample) so cells can be partially re-evaluated without dropping audio. Examples show a 200 Hz sine, pulse-width and FM-style modulation, arithmetic mixing, band/pass and low-pass filtering, a compressor, envelope attack/release driven by a clock, drum primitives and live knobs plus a stereo-oscillographic visualization of the output.
