Replace use of a circular buffer to hold short - window of data with a linear buffer. - Linear buffer requires that data is periodically copied from the end if - the buffer back to the beginning. However, it also means that the - calc_output() function no longer needs to calculate the next data index - modulo the buffer length. - Since the data index is calculated 40 times (minimum) per output sample, - and the copy from end of buffer to start of buffer is done every 1000 or - so output samples, this change results in a significant speedup (up to - about 50% improvement for SRC_SINC_FASTEST). - Memory use has increased somewhat (max 6k per channel per converter) due - to this fix, but that should go down again during next phase of - refactoring. - - * examples/varispeed-play.c - Fixed a bug where data_in and data_out buffers were overlapping. - -2003-01-03 Erik de Castro Lopo <erikd AT mega-nerd DOT com> - - * doc/win32.html - Completed documentation on compiling for Win32. - - * doc/*.html - Added links to Win32 compiling information. - - * configure.ac tests/Makefile.am - Detect libefence and link it to all the test programs if configured - with --enable-debug. - - * tests/utils.[ch] - New function force_efence_banner(). - - * tests/*test.c - Add a call to force_efence_banner() to force printing of the Electric Fence - banner at start of program. - -2003-01-02 Erik de Castro Lopo <erikd AT mega-nerd DOT com> - - * configure.ac - Added --enable-debug configuration flag. - - * tests/termination_test.c - More modifications to catch corner cases. - Added extra test to check for negative return values for input_frames_used - and output_frames_gen fields of SRC_DATA. - - * src/src_zoh.c src/src_linear.c - Fixed more bugs found using modified streaming_test. - - * src/samplerate.c - Set input_frames and output_frames of SRC_DATA to zero if they are negative. - Add check for overlapping SRC_DATA data_in and data_out arrays. - - * doc/api_full.html - Document the fact that the SRC_DATA->data_in and data_out arrays may not - overlap.
