I measured encoding speed of 24-bit WAV files. It turns out that 32-bit encoder made by GCC is ~1.7x times slower than 32-bit encoder made by MSVS.
It seems that GCC creates inefficient code for 32bit * 32bit -> 64bit multiplication for 32-bit architecture. This problem affects FLAC__lpc_compute_residual_from_qlp_coefficients_wide() and FLAC__lpc_restore_signal_wide() functions. Is there any way to fix this (apart from rewriting these 2 functions in 32-bit asm) ? _______________________________________________ flac-dev mailing list flac-dev@xiph.org http://lists.xiph.org/mailman/listinfo/flac-dev
