Real-time audio DSP pipelines require preallocated state and zero dynamic allocations on the audio thread. You enforce deterministic memory usage by utilizing SPSC queues for thread communication and STFT pipelines for analysis.
The best way to communicate between audio and worker threads in a DSP engine is using lock-free concurrency patterns. Specifically, SPSC queues provide real-time safe communication between threads without blocking the audio callback.
You can implement biquad filters and parameter smoothing in C++ or Rust. The approach provides guidance for testing, performance tuning, and portability across both languages within multi-threaded contexts.
Real-time audio processing drops samples when allocating state because dynamic allocations on the audio thread cause non-deterministic latency. You must use preallocated RT-safe state to ensure deterministic memory usage during processing.
This approach works for offline audio analysis and STFT pipelines. The real-time DSP architecture applies to both real-time audio engines and offline analysis, utilizing preallocated state for STFT processing.
