2014-06-04Correct name for xtract_peak()Jamie Bullock
2014-06-03Add ring buffer implementationJamie Bullock
2014-06-03Add xtract_peak() determines whether the 'current' value is a peakJamie Bullock
2014-06-03Add "stateful" feature type with initial feature "last n"Jamie Bullock
Stateful feature extraction functions are functions that require state to be maintained between successive calls. This is necessary, for example when an accumulation of values is required, or changes need to be measured over time. The initial xtract_last_n() function accumulates the last N (single) values from *data and writes them to *result
2014-03-27add VC2012 project to compile static and dynamic lib, also fix some CQ
issues
2014-03-17Fixed bugs in xtract_failsafe_f0(). Should now actually be failsafe. Only ↵Jamie Bullock
exception is silent input.
2014-03-11Set result value before returnJamie Bullock
2014-03-11Set *result to note value in xtract_midicent(). Fixes bug.Jamie Bullock

2014-03-07Fix potential memory leakJamie Bullock
2014-02-17xtract_hps, made it more in the style of the library and octave error ↵Sean Enderby
correction bit
2014-02-17quick fix to xtract_irregularity_j and a sort of working xtract_hpsSean Enderby
2014-02-12Include float.h on platforms that don't have DBL_MAX defined in limits.hJamie Bullock
2014-02-11Make xtract_lowest_value() return XTRACT_NO_RESULT if all values in the ↵Jamie Bullock
input data are below or equal to threshold value. Fixes #46 If XTRACT_NO_RESULT is returned, *result will be set to DBL_MAX
2013-07-08Optimise xtract_smoothness() by removing call to malloc(). Also fix bug in ↵Jamie Bullock
xtract_smoothness() where *result was uninitialised but used in calculation.
