Audio signal processing, physical modeling synthesis, and machine learning for audio.

• 🌍 JOS Home Page — online books, papers, and courses
• 🔭 Currently working on audio signal processing and machine-learning projects
• 💬 Ask me about digital signal processing, AI in audio, and computational acoustics
• 📫 Reach me through GitHub or my professional channels

• l2hmj — LaTeX2HTML with MathJax: the publishing toolchain behind the JOS online books (Mathematics of the DFT, Physical Audio Signal Processing, ...). Equations are rendered by MathJax instead of images, so they copy/paste with their LaTeX source intact (LLM-friendly), scale cleanly, and are accessible to screen readers.
• mcp-servers-jos — MCP servers, including a JUCE documentation server for Claude Code, Codex, Cursor, and other MCP clients (MIT)
• MidiToChords — JUCE-based AU/Standalone MIDI plugin that displays chord names from MIDI input (MIT)

• neural-spectral-modeling-template (NSMT) - Adapts LHTE to audio spectrograms and basic Synth-Matching experiments (MIT)
• lightning-hydra-template-extended (LHTE) - Adds dataset formats, architectures, and loss functions to the LHT
• TonicNet-PyTorch - PyTorch reimplementation of TonicNet: polyphonic Bach chorale generation
• FormFinder - Discover popular-music song structure (Intro/Verse/Chorus/Bridge/...)
• dsp2seq - Sequence models as signal processing (talk overheads)

• jos_faust - C++ modules for JUCE generated from jos functions in the Faust Libraries (paused experiment; a hand-optimized successor is in development)
• modalmodel - Experiments in modal modeling
• bowed-physics - Research and educational physical models of bowed strings
• MouthpieceSim - Simulation for an electronic wind-instrument mouthpiece sensor
• SoundInstallationSimulator - Browser-based modular sound installation simulator

• MidiToChords - Chord names from MIDI input (AU/Standalone, MIT)
• AutoJust - Master-bus adaptive Just Intonation retuner
• TileCraft - Grid-based touch control-surface designer (research prototype)
• MidiPredict - Play a MIDI file slightly in advance of live incoming MIDI

• l2hmj - LaTeX2HTML with MathJax (see Featured above)
• jos-latex - Shared LaTeX infrastructure for JOS textbooks and papers
• docker-w - Docker + Claude Code + LaTeX dev environment
• wiki - LLM Wiki: persistent interlinked knowledge bases built with AI agents
• mcp-template - Barebones starting point for a new MCP server
• JUCEModulesDoc - Doxygen-format documentation for JUCE modules

• 320c-starter-code - Music 320c starter code
• ai-miracle-decade-plus - Landing page for the AI Miracle Decade+ self-paced course

Many of my repos are git forks for study or contribution. When I fork a repo, I typically create a jos branch first thing for my changes, merging main/master into that over time.

• foleys-gui-magic - A GUI builder module for JUCE (feature branch in active use)
• juce-toys - Debugging utilities in a JUCE Module with NatVis and LLDB customizations
• scipy - SciPy library main repository
• makemore - Autoregressive character-level language model with Mamba implementation
