Thought dump
Record the entire idea quickly: sound, workflow, user, references, controls, and intended feeling.
From idea to installable product
Plugin Development Process
A high-level map of the system I use to plan, build, test, and release professional audio plugins with AI-assisted development.

The source of truth
Start with the product, not the code.
A voice-to-text thought dump becomes a concrete product brief, technical plan, and master prompt that keeps every later decision aligned.
Product brief
Turn the raw idea into scope, signal flow, parameter map, supported formats, and measurable milestones.
Master prompt
Give the AI partner durable context, constraints, quality standards, and a staged implementation path.
Scope discipline
Separate the smallest strong product from ideas that belong in later versions.
A repeatable workspace
Build the system around the plugin.
Good infrastructure lets development resume cleanly, makes changes traceable, and gives Codex or Claude the right project context every time.
JUCE + CMake
A clean project structure for source, DSP, assets, presets, tests, installers, and documentation.
GitHub workflow
Branches, commits, issues, releases, and version tags preserve decisions and make regressions recoverable.
Skills and project memory
Focused rules, status notes, and reusable context keep AI-assisted work consistent across sessions.
Build commands
Known commands handle build, install, launch, validate, and package steps with less manual friction.
Listen, respond, repeat
Develop the sound in a tight feedback loop.
The audio test host keeps DSP experimentation fast. Each pass changes one focused part, rebuilds automatically, and returns immediately to listening.
01Define the audible target
02Implement a focused change
03Build and audition
04Describe the result
05Refine and repeat
Standalone auditioning
Test processing without carrying the full product interface through every experiment.
Plain-language feedback
Translate what the ear hears into a precise next change for Codex or Claude.
Technical guardrails
Check smoothing, gain, CPU, sample rates, denormals, invalid values, clicks, and extreme settings.
Record-speed iteration
Small loops shorten the distance between an idea, a build, and an informed listening decision.
The real advantage
The value is the full system: listening judgment, project context, repeatable testing, disciplined prompts, and carefully scoped changes.
Sound before polish
Prove the plugin before designing it.
The working DSP moves into a stripped-down JUCE plugin with a functional temporary interface. The priority is host behavior, not visual finish.
Processor first
Stable DSP, safe audio-thread behavior, sensible defaults, and predictable bypass behavior.
Parameters and state
Permanent IDs, ranges, units, automation, smoothing, session recall, and preset foundations.
Real host builds
AU, VST3, and Standalone builds are exercised in actual production environments early.
Maintainable modules
DSP, state, presets, interface, and platform concerns remain clearly separated.
From wireframe to product
Design a UI around the workflow.
Visual development begins after the control set is understood. AI image tools help explore directions; a deliberate asset system turns the chosen direction into a usable interface.
Wireframe first
Establish control grouping, reading order, meter placement, and the primary user journey.
AI concept generation
Use Higgsfield and image-generation tools for visual directions, references, and rapid ideation.
Reusable assets
Build consistent knobs, switches, meters, panels, menus, typography, and interaction states.
Real plugin behavior
Connect every control, then verify automation, resizing, scaling, presets, meters, and state recall.
Design principle
Generated imagery is concept material until it has been refined into a coherent, maintainable production system.
A build is not a release
Test the promise made to the customer.
Quality assurance covers sound, sessions, hosts, systems, and installers. A defined support matrix keeps testing rigorous and realistic.
Signal conditions
Mono, stereo, sample rates, buffer sizes, offline render, silence, clipping, and extreme control values.
Recall and automation
Save, close, reopen, preset recall, automation playback, undo, bypass, and older state handling.
Cross-DAW behavior
Logic, Ableton, FL Studio, Reaper, Studio One, and the hosts the product officially supports.
Clean-machine checks
macOS and Windows scanning, install paths, permissions, architecture, updates, and uninstall behavior.
Structured outside feedback
Turn beta reports into useful decisions.
A private beta is a controlled release cycle with versioned installers, clear test goals, structured reporting, and fast issue triage.
01Package a versioned beta
02Distribute to the right mix
03Collect structured reports
04Triage by release risk
05Patch and close the loop
Representative testers
Different DAWs, operating systems, production styles, and levels of technical experience.
Useful reports
Plugin version, system, host, exact reproduction steps, expected result, and supporting files.
Trusted customer downloads
Finish the product outside the plugin window.
Signing, installers, delivery, documentation, and support are part of the engineering work, not administrative details at the end.
Sign and notarize
Developer Program setup, binary signing, installer packaging, notarization, stapling, and clean-system verification.
Code signing
Certificate setup, signed binaries and installers, timestamping, and Windows reputation considerations.
Release artifacts
Versioned packages, validated contents, download integrity, release notes, and aligned source tags.
Product operations
Documentation, licensing, factory presets, storefront delivery, onboarding, support, and maintenance releases.
Release standard
A great-sounding plugin that customers cannot install, trust, recall, or update reliably is not finished.
