...; should keep all current settings, generate a new stream header and clear everything for encoding a new signal. It' clear that current settings, re-creating windows, cpu-dependent functions, etc could be kept around. I was not quickly able to extract all the necessary initialization from "init_stream_internal_" into a new "FLAC__stream_encoder_restart" function.

Hello, I manage to successfully write 8, 16 and 24 bit, all stereo, FLAC files. But when I try to write 32 bit FLACs my program crashes. *FLAC__stream_encoder_set_bits_per_sample *is called to match the desired bit depth (8, 16, 24, 32) It's the same code for all bit depths, i provide a fixed-size signed int buffer to the lib (size=16384), with values with appropriate ranges for each bit

Thanks I did run this on my machine with 4 i5-4440 cores wich accoring to /proc/cpu has svx2 support. However I'm not sure if flac was actually using the AVX2 code.
