| |
| 2004-05-25 Erik de Castro Lopo <erikd AT mega-nerd DOT com> |
| |
| * src/samplerate.c |
| Fix a bug in src_callback_read() reported by Mark Deggeller. Data retreived |

| next call. |

| Add fields saved_frames and saved_data to SF_PRIVATE struct for storing |
| data between sucessive calls to src_callback_read(). |

| |
| 2003-10-27 Erik de Castro Lopo <erikd AT mega-nerd DOT com> |
| |
| * tests/calc_snr.c |
| SNR calculation was being screwed up because the peak detector was |
| mistaking side lobes caused by the windowded FFT as noise/aliasing peaks. |
| Therefore added code to wipe out the troughs between peaks which erases |
| the side lobe peaks without affecting the noise/aliasing peaks. |
| |

| Fixed problems with converters shown up by improved tests. |
| |
| 2003-09-25 Erik de Castro Lopo <erikd AT mega-nerd DOT com> |

| 2003-08-05 Erik de Castro Lopo <erikd AT mega-nerd DOT com> |

| |
| 2003-01-05 Erik de Castro Lopo <erikd AT mega-nerd DOT com> |
| |
| * src/src_sinc.c |
| Phase one or refactoring. 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. |
| |
