+
+ * src/src_sinc.c
+ Fix a read beyond end of coefficent array problem uncovered by gcc-4.8's
+ -fsanitize=address feature and reported by Cristian RodrÃguez.
+
+ Since this is reading filter coefficients from rodata memory and no write
+ is possible, is is not exploitable from a security point of view.
+
+ Solution was to reduce the half_coeff_len value for each filter by one.

+
+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.

+ the side lobe peaks without affecting the noise/aliasing peaks.
+
+ * tests/multi_channel_test.c

+
+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.

+
+ * configure.ac
