DSP — Digital Signal Processing for Audio

A comprehensive reference for implementing real-time audio DSP algorithms in C/C++. Derived from the musicdsp.org community archive covering two decades of practitioner knowledge.

When to Use This Skill

• Implementing audio filters, effects, synthesizers, or analyzers in C/C++
• Writing processBlock(), process(), or sample-by-sample DSP loops
• Designing biquad coefficients, Moog ladder filters, or state variable filters
• Building delay lines, reverbs, compressors, waveshapers, or stereo processors
• Generating bandlimited waveforms, noise, or envelopes
• Optimizing audio code with fast math approximations or denormal prevention
