Bridging pure mathematical modeling with hardware constraints to guarantee deterministic latency and cycle-accurate execution across production audio systems.
Codec architecture
Adaptive spatial filtering
Fixed-point translation
Developing low-bitrate psychoacoustic speech and audio codecs optimized for tight direct memory access transfers and battery-constrained embedded DSP targets.
Multi-microphone beamforming arrays, sub-band acoustic echo cancellation, and real-time noise suppression with guaranteed linear phase alignment under tight cycle budgets.
Porting float32 algorithmic prototypes into cycle-accurate Q31 and Q15 fixed-point architectures without dynamic range clipping or tap count expansion.

Bandwidth dictates deterministic latency
Real-time audio processing leaves zero margin for non-deterministic cache misses. Theoretical math must align with physical bus topology and cycle-accurate memory access.
Available for principal-level signal architecture, firmware optimization, and technical consulting on mission-critical audio and embedded sensing hardware.
