Are these functions required to be bit-exact as defined by the specification or are they implementation-dependent? I ask because they are quite similar to our existing autocorrelation and levinson-durbin functions (though obviously 16-bit fixed-point rather than floating-point). Also, is a Hamming window required or can some other window function be used? -Justin _______________________________________________ FFmpeg-soc mailing list [email protected] https://lists.mplayerhq.hu/mailman/listinfo/ffmpeg-soc
