You say

I need to implement a saturation stage in my JUCE plugin using a vectorized tanh function. How do I handle the SIMD lane processing while keeping the audio thread safe?

Your agent does

Use the degree-7 exp approximation for tanh, routing the 8-wide batch through _mm256_fmadd_ps. Clamp inputs to [-8.0, 8.0] to prevent NaNs. Use an SPSC queue to push parameter updates and ensure all std::atomic members are aligned to 64 bytes to prevent false sharing.

What you get

Develop allocation-free audio callbacks for VST3/CLAP plugins.Optimize DSP math using AVX2 SIMD without denormal stalls.Implement lock-free parameter synchronization between UI and Audio threads.Generate stable IIR filter coefficients for high-shelf and peak filters.

About this skill

Build low-latency audio engines, VST3/CLAP plugins, and SIMD DSP without allocator blowups or denormal stalls. Use this whenever you touch real-time audio callbacks, parameter atomics, or AVX vectorization.
