wasapi-development

Design, implement, review, debug, and optimize Windows Audio Session API (WASAPI) and Core Audio code on Windows 10/11. Use for audio rendering, microphone capture, system loopback, process loopback, low-latency audio, shared/exclusive streams, IAudioClient/IAudioClient2/IAudioClient3, IAudioRenderClient, IAudioCaptureClient, MMDevice endpoint selection, audio sessions, device switching, stream recovery, format negotiation, buffer processing, MMCSS, and native interop from C++, C#, .NET, WinUI 3, WPF, or other Windows desktop applications.

winui

Root skill that groups the WinUI 3 sub-skills used in this project. This is a router: it lists the sub-skills under sub-skills/ and tells the agent which one to load for the task at hand (design, dev workflow, code review, packaging, UI testing). Use when a WinUI 3 app task matches one of those areas; then load the matching sub-skill's SKILL.md.

2026-08-11

winui-packaging

MSIX packaging, code signing, and distribution for WinUI 3 apps — build for release, certificate generation (winapp cert generate), certificate trust, code signing (winapp sign), self-contained deployment, CI/CD with GitHub Actions, and Microsoft Store submission. Use when preparing for release, creating MSIX installers, managing certificates, setting up CI/CD packaging, or publishing to the Microsoft Store.

2026-08-11

build-full

Compile, test, and deploy the Echos Live Music Visualizer application from source. Handles environment verification, Rust and C# unit tests, MSIX packaging, and installation. Use when building EchoVisualizer from the repository, whether for development or production deployment. Requires .NET SDK, Rust toolchain, and PowerShell (Windows). A public development certificate can be trusted per-user.

WASAPI Development

Use this skill when working directly with WASAPI, Core Audio, MMDevice, audio sessions, endpoint volume, or low-level Windows audio streams.

Treat audio streaming code as real-time, stateful, resource-sensitive systems code, not ordinary application code.

Reference documents

This skill is split across modular reference files in references/. Load only the document(s) relevant to the current task.

Reference

Contents

Load when

references/overview.md

Goals, when to use WASAPI, inspect the existing system, core optimization principle.

Starting any WASAPI work; orientation.

references/scenario-and-architecture.md

Classify direction/endpoint/mode/latency/processing; Core Audio object chain; recommended class responsibilities.

Selecting the stream scenario; designing structure.

references/modes-latency-scheduling.md

Shared vs exclusive mode; IAudioClient3; latency as negotiated; event-driven streaming; real-time bounds; MMCSS.

Choosing mode/latency; scheduling the audio worker.

references/audio-formats.md

Format negotiation, GetMixFormat / IsFormatSupported, format ownership, sample conversion, multichannel.

Negotiating or converting audio formats.

references/render-and-capture.md

IAudioRenderClient / IAudioCaptureClient buffer protocol; priming; capture flags; timing/positions.

Implementing render or capture loops.

references/loopback.md

Endpoint loopback, process loopback, RAW mode, MATCH_FORMAT.

Capturing system/process audio or bypassing processing.

references/devices-routing-changes.md

MMDevice endpoint selection, default routing, IMMNotificationClient, invalidation/recovery.

Choosing devices; handling device changes.

references/sessions-and-volume.md

Audio categories, sessions, endpoint vs session volume.

Session/volume control.

references/threading-and-lifecycle.md

COM/threading, async activation, lifecycle state machine, Start/Stop/Reset, cancellation, locking.

Stream lifecycle and concurrency.

references/data-flow.md

Backpressure, buffer ownership across threads, silence, discontinuities.

Connecting a slow consumer; handing off audio data.

references/diagnostics-and-performance.md

Structured diagnostics; investigating glitches/underruns.

Debugging or optimizing audio.

references/managed-and-errors.md

C#/.NET guidance, error categorization, fallback policy.

Managed implementations; error handling.

references/testing.md

Unit vs integration testing, review checklist, anti-patterns.

Testing and reviewing WASAPI code.

references/workflow.md

Step-by-step implementation workflow; source-of-truth policy.

Implementing a new or modified audio feature.

How to use

Read references/overview.md for orientation.

Read the specific references/*.md documents for the task (format selection, capture loop, device handling, etc.).

Apply the guidance to the host project, preserving its existing abstractions and conventions.
