PROFILE
Yunho Huh
Yunho worked on enhancing numerical precision and alignment in the libsdl-org/opus repository, focusing on core audio processing math functions. Over two months, Yunho improved the accuracy of celt_log2 and celt_exp2 by refining coefficients and introducing a Remez-based approximation, raising precision targets to 20-24 bits. The work included updating mathops.h and expanding unit tests to ensure stability and reliability in both fixed-point and floating-point paths. Using C programming, DSP, and fixed-point arithmetic, Yunho’s contributions addressed divergence between implementations, resulting in more robust audio encoding and decoding with improved test coverage and numerical consistency across platforms.
