Building a Real-time Audio Processing App with SKSL Shaders in .NET MAUI

Nick uses the open-source SolTempo app as a deep technical case study in real-time audio processing with .NET MAUI. The article covers the end-to-end pipeline from audio capture and transforms through pitch and tempo analysis, then shows how a single Skia-backed canvas and custom SKSL shaders drive the visual layer.

What you’ll learn

• How SkiaCamera can be used for audio monitoring, sample processing, and feeding live analysis modules.
• Why a single-canvas DrawnUI approach can work well for shader-heavy interfaces, transitions, overlays, and effects.
• How SKSL shaders, live shader editing, and custom visual effects can be used to build more ambitious MAUI experiences.
