49 | |
50 * examples/sndfile-resample.c | |
51 Prevent creation of double length output files when conversion is restarted | |

54 | |
55 * src/samplerate.h tests/termination_test.c | |
56 Revert change that moved the src_ratio field to the start of SRC_DATA | |
57 struct. This change does have some merit, but is not worth it considering | |
58 that its an API change. This idea will be reconsidered when the API does | |
59 change. | |

81 input_frames field of SRC_DATA was zero. | |
82 | |
83 2009-09-16 Erik de Castro Lopo <erikd AT mega-nerd DOT com> | |
84 | |

108 | |
109 * src/samplerate.h | |
110 Move src_ratio field to the start of the SRC_DATA struct to ensure it gets | |
111 aligned correctly when either the library or client code gets compiled with | |
112 -malign-double. | |
113 | |
114 * configure.ac | |
115 Bump version to 1.0.0 due to API change. | |
116 | |

132 | |
133 * src/src_sinc.c | |
134 Fix a segfault which occurs when memcpy is passed a bad length parameter. | |
135 This bug has zero security implications beyond the ability to cause a | |
136 program hitting this bug to exit immediately with a segfault. | |
137 See : http://www.mega-nerd.com/erikd/Blog/2009/Feb/14/index.html | |

665 | |
666 * src/samplerate.c | |
667 Fix a bug in src_callback_read() reported by Mark Deggeller. Data retreived | |

670 | |
671 * src/common.h | |
672 Add fields saved_frames and saved_data to SF_PRIVATE struct for storing | |
673 data between sucessive calls to src_callback_read(). | |

711 | |
712 * src/samplerate.h src/samplerate.c | |
713 Added functions for short->float and float->short conversions on arrays | |
714 of data. This will make it a little easier for people who need the | |
715 input or output data in shorts rather than floats. | |
716 | |
717 * configure.ac | |
718 Added tests for CPU clipping mode which was required for the float to | |
719 short conversion. | |
720 | |

725 | |
726 * src/src_zoh.c src/src_linear.c | |

735 | |
736 * tests/calc_snr.c | |
737 SNR calculation was being screwed up because the peak detector was | |
738 mistaking side lobes caused by the windowded FFT as noise/aliasing peaks. | |
739 Therefore added code to wipe out the troughs between peaks which erases | |
740 the side lobe peaks without affecting the noise/aliasing peaks. | |
741 | |
742 * tests/multi_channel_test.c | |
743 Added a callback_test to work on multiple channels. | |
744 | |

761 src_callback_new() is not used with src_process() etc. | |

775 More work on getting callback based API working. | |

796 | |
797 * examples/sndfile-resample.c | |
798 Turn on clipping of output when saving to integer PCM output formats. | |
799 | |
800 2003-08-21 Erik de Castro Lopo <erikd AT mega-nerd DOT com> | |
801 | |
802 * tests/callback_test.c | |
803 Start work on a callback based API. The implementation will be done | |
804 in this test program first and when it is working, the code that does | |
805 the work will be moved back to the library code. | |
806 | |
807 2003-08-19 Erik de Castro Lopo <erikd AT mega-nerd DOT com> | |
808 | |

817 2003-08-05 Erik de Castro Lopo <erikd AT mega-nerd DOT com> | |
818 | |
819 * tests/snr_bw_test.c | |
820 Added test for conversion ratio of 1.0 for all converters. For this | |
821 conversion ratio, all converters have a better than 149db SNR ratio. | |

823 * src/src_linear.c | |
824 Changes to make this converter work more like src_zoh.c. | |

890 constants are assigned to floats. | |
891 | |

893 Added #include <string.h> to prevent compiler warning about use of memset() | |
894 function. | |
895 | |
896 2003-01-13 Erik de Castro Lopo <erikd AT mega-nerd DOT com> | |
897 | |
898 * src/samplerate.[ch] | |
899 Added function src_set_ratio() at the suggestion of Dr William Bland. | |
900 | |
901 * doc/api_full.html | |

916 Added empty header file for Win32. | |
917 | |

920 | |
921 2003-01-05 Erik de Castro Lopo <erikd AT mega-nerd DOT com> | |
922 | |
923 * src/src_sinc.c | |
924 Phase one or refactoring. Replace use of a circular buffer to hold short | |
925 window of data with a linear buffer. | |
926 Linear buffer requires that data is periodically copied from the end if | |
927 the buffer back to the beginning. However, it also means that the | |
928 calc_output() function no longer needs to calculate the next data index | |
929 modulo the buffer length. | |
930 Since the data index is calculated 40 times (minimum) per output sample, | |
931 and the copy from end of buffer to start of buffer is done every 1000 or | |
932 so output samples, this change results in a significant speedup (up to | |
933 about 50% improvement for SRC_SINC_FASTEST). | |
934 Memory use has increased somewhat (max 6k per channel per converter) due | |
935 to this fix, but that should go down again during next phase of | |
936 refactoring. | |
937 | |
938 * examples/varispeed-play.c | |
939 Fixed a bug where data_in and data_out buffers were overlapping. | |
