NAudio 3 Effects Framework

NAudio 3 introduces a comprehensive audio effects framework built around a new IAudioEffect interface, which exposes a Process method operating on Span<float>, a Reset method, and latency reporting. An EffectChain allows chaining, reordering, and dynamically adding/removing effects during playback. The library ships with built-in effects including Delay, Reverb, Compression, EQ, Saturation, and Gate. A new IParameterized interface lets effects expose typed parameters (continuous, choice, toggle, and read-only meters) with thread-safe updates and a ParameterSmoother to avoid audio artifacts on sudden changes. A WPF demo app showcases real-time ASIO processing, file rendering through effect chains, and live parameter adjustment. NAudio 3 is still in preview but nearing release.
